方法一 通過GridView(簡評：方法比較簡單，但是只適合生成格式簡單的Excel，且無法保留VBA代碼),頁面無刷新

aspx.cs部分

代碼如下:

 
using System;  
          
using System.Collections;  
          
using System.Configuration;  
          
using System.Data;  
          
using System.Web;  
          
using System.Web.Security;  
          
using System.Web.UI;  
          
using System.Web.UI.HtmlControls;  
          
using System.Web.UI.WebControls;  
          
using System.Web.UI.WebControls.WebParts;  
          
using System.Text;  
          
public partial class DataPage_NationDataShow : System.Web.UI.Page  
          
{  
          
private Data_Link link = new Data_Link();  
          
private string sql;  
          
protected void Page_Load(object sender, EventArgs e)  
          
{  
          
Ajax.Utility.RegisterTypeForAjax(typeof(DataPage_NationDataShow));  
          
}  
          
protected void btnExcel_Click(object sender, EventArgs e)  
          
{  
          
string strExcelName = "MyExcel";  
          
strExcelName = strExcelName.Replace(@"/", "");  
          
Data_Link link = new Data_Link();  
          
string strSQL = this.hidParam.Value;  
          
DataSet ds = new DataSet();  
          
ds = link.D_DataSet_Return(strSQL);//獲得想要放入Excel的數據  
          
gvExcel.Visible = true;  
          
gvExcel.DataSource = null;  
          
gvExcel.DataMember = ds.Tables[0].TableName;  
          
gvExcel.DataSource = ds.Tables[0];  
          
gvExcel.DataBind();  
          
ExportToExcel(this.Page, gvExcel, strExcelName);  
          
}  
          
protected void gvExcel_RowDataBound(object sender, GridViewRowEventArgs e)  
          
{ }  
          
public override void VerifyRenderingInServerForm(Control control)  
          
{ }  
          
/// <summary>  
          
/// 工具方法，Excel出力(解決亂碼問題)  
          
/// </summary>  
          
/// <param name="page">調用頁面</param>  
          
/// <param name="excel">Excel數據</param>  
          
/// <param name="fileName">文件名</param>  
          
public void ExportToExcel(System.Web.UI.Page page, GridView excel, string fileName)  
          
{  
          
try  
          
{  
          
foreach (GridViewRow row in excel.Rows)  
          
{  
          
for (int i = 0; i < row.Cells.Count; i++)  
          
{  
          
excel.HeaderRow.Cells[i].BackColor = System.Drawing.Color.Yellow;  
          
}  
          
}  
          
excel.Font.Size = 10;  
          
excel.AlternatingRowStyle.BackColor = System.Drawing.Color.LightCyan;  
          
excel.RowStyle.Height = 25;  
          
page.Response.AppendHeader("Content-Disposition", "attachment;filename=" + fileName);  
          
page.Response.Charset = "utf-8";  
          
page.Response.ContentType = "application/vnd.ms-excel";  
          
page.Response.Write("<meta http-equiv=Content-Type content=text/html;charset=utf-8>");  
          
excel.Page.EnableViewState = false;  
          
excel.Visible = true;  
          
excel.HeaderStyle.Reset();  
          
excel.AlternatingRowStyle.Reset();  
          
System.IO.StringWriter oStringWriter = new System.IO.StringWriter();  
          
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter); 
          
excel.RenderControl(oHtmlTextWriter);  
          
page.Response.Write(oStringWriter.ToString());  
          
page.Response.End();  
          
excel.DataSource = null;  
          
excel.Visible = false;  
          
}  
          
catch (Exception e)  
          
{  
          
}  
          
}  
          
}

aspx部分

復制代碼代碼如下:

 
<head runat="server">  
          
<script type="text/javascript">  
          
//Excel DownLoad  
          
function excelExport(){  
          
var hidText = document.getElementById("hidParam");  
          
hidText.value = "some params";  
          
document.getElementById("ExcelOutput").click();  
          
}  
          
</script>  
          
</head>  
          
<body onload="pageInit()">  
          
<form id="form1" runat="server">  
          
<input type="button" value="EXCEL下載" style="width:100px;" onclick="excelExport()" id="excelBut" />  
          
<input id="hidParam" type="text" runat="server" style="display:none;"/>  
          
<asp:Button runat="server" ID="ExcelOutput" style="display:none" Text= "EXCEL出力" Width="0px" onclick="btnExcel_Click" UseSubmitBehavior="false"/>  
          
<asp:GridView ID="gvExcel" runat="server" Height="95px" OnRowDataBound="gvExcel_RowDataBound" Visible="False"></asp:GridView>  
          
</form>  
          
</body>

在剛才的aspx.cs代碼中

復制代碼代碼如下:

 
foreach (GridViewRow row in excel.Rows)  
          
{  
          
for (int i = 0; i < row.Cells.Count; i++)  
          
{  
          
excel.HeaderRow.Cells[i].BackColor = System.Drawing.Color.Yellow;  
          
}  
          
}

這部分是給表頭添加樣式。

有時候為了便於瀏覽，需要給交叉行添加樣式，簡單點的可以用下面這種：

復制代碼代碼如下:

excel.AlternatingRowStyle.BackColor = System.Drawing.Color.LightCyan;

但是細看一下會發現它把一整行的樣式都改變了，包括后面那些沒有用到的列。

解決辦法是有，不過比較繁瑣，就是修改每個單元格的樣式。

復制代碼代碼如下:

 
int rowCount = excel.Rows.Count;  
          
int colCount = excel.HeaderRow.Cells.Count;  
          
for (int i = 0; i < rowCount; i++)  
          
{  
          
for(int j=0;j<colCount; j++)  
          
{  
          
excel.Rows[i].Cells[j].BackColor = System.Drawing.Color.LightCyan;  
          
}  
          
}

方法二 通過DataGrid(與方法一基本相同),頁面無刷新

aspx.cs部分

復制代碼代碼如下:

 
public override void VerifyRenderingInServerForm(Control control)  
          
{}  
          
/// <summary>  
          
/// エクセル出力イベント  
          
/// </summary>  
          
/// <param name="sender"></param>  
          
/// <param name="e"></param>  
          
private void ExcelBut_Click(object sender, System.EventArgs e)  
          
{  
          
DataGrid dgExcel = new DataGrid();  
          
try  
          
{  
          
DataSet ds = getExcelData(this.PageParams.Value);//出力データを取得する  
          
if(ds.Tables[0].Rows.Count>0)  
          
{  
          
//エクセルへデータを投入する  
          
string execlName= "MyExcel";  
          
Encoding encodingType=System.Text.Encoding.UTF8;  
          
dgExcel.DataMember=ds.Tables[0].TableName;  
          
dgExcel.DataSource=ds.Tables[0];  
          
Response.Buffer = true;  
          
Response.Charset = "utf-8";  
          
Response.AppendHeader("Content-Disposition", "attachment;filename=" + execlName+ ".xls");  
          
Response.ContentEncoding = encodingType;  
          
Response.ContentType = "application/ms-excel";  
          
StringWriter oStringWriter = new StringWriter();  
          
HtmlTextWriter oHtmlTextWriter = new HtmlTextWriter(oStringWriter);  
          
dgExcel.DataBind();  
          
dgExcel.Visible = true;  
          
dgExcel.RenderControl(oHtmlTextWriter);  
          
Response.Write(oStringWriter.ToString());  
          
Response.Flush();  
          
Response.Close();  
          
dgExcel.DataSource = null;  
          
dgExcel.Visible = false;  
          
}  
          
else  
          
{  
          
Response.Write("<script>alert('xxxxxx')</script>");  
          
}  
          
}  
          
catch(Exception ex)  
          
{  
          
Response.Write("<script>alert('oooooo')</script>");  
          
}  
          
}

aspx部分

復制代碼代碼如下:

 
<head runat="server">  
          
<script type="text/javascript">  
          
//Excel DownLoad  
          
function excelExport(){  
          
var hidText = document.getElementById("hidParam");  
          
hidText.value = "some params";  
          
document.getElementById("ExcelOutput").click();  
          
}  
          
</script>  
          
</head>  
          
<body onload="pageInit()">  
          
<form id="form1" runat="server">  
          
<input type="button" value="EXCEL下載" style="width:100px;" onclick="excelExport()" id="excelBut" NAME="excelBut"/>  
          
<input id="hidParam" type="text" runat="server" style="display:none;" NAME="hidParam"/>  
          
<asp:Button runat="server" ID="ExcelOutput" style="display:none" Text= "EXCEL出力" Width="0px" onclick="btnExcel_Click" UseSubmitBehavior="false"/>  
          
<asp:datagrid id="gvExcel" Visible="False" Runat="server" style="Z-INDEX: 107; POSITION: absolute; TOP: 72px; LEFT: 520px"  
          
Width="80px" Height="40px"></asp:datagrid>  
          
</form>  
          
</body>

方法三 以XML形式的Excel方式(可以設置豐富的樣式，並可以有多個sheet，但需要模版。速度很快，但生成的文件較大，且無法保留VBA代碼)

具體方法：把模版以 XML Document形式另存為A.xml。然后參照A.xml中的內容即可

復制代碼代碼如下:

             
private void ExcelBut_Click(object sender, System.EventArgs e)  
          
{  
          
DataSet ds = new DataSet();  
          
string ExcelFileName = "";  
          
DataRow dr=[------列名信息-------];  
          
try  
          
{  
          
ExcelFileName = Path.Combine(Request.PhysicalApplicationPath + "/ExcelFile", "MyExcel.xls");  
          
//獲取Excel需要的數據  
          
ds = [------獲得數據-------];  
          
if (ds.Tables.Count == 0)  
          
{  
          
Response.Write("<script type='text/javascript'>alert('無數據');</script>");  
          
return;  
          
}  
          
int sheetNum = ds.Tables.Count / 2;  
          
StreamWriter writer = new StreamWriter(ExcelFileName, false);  
          
//Styles標簽前面的信息相當於'頭信息'，不需要改變  
          
writer.WriteLine("<?xml version=\"1.0\"?>");  
          
writer.WriteLine("<?mso-application progid=\"Excel.Sheet\"?>");  
          
writer.WriteLine("<Workbook xmlns=\"urn:schemas-microsoft-com:office:spreadsheet\"");  
          
writer.WriteLine("xmlns:o=\"urn:schemas-microsoft-com:office:office\"");  
          
writer.WriteLine("xmlns:x=\"urn:schemas-microsoft-com:office:excel\"");  
          
writer.WriteLine("xmlns:ss=\"urn:schemas-microsoft-com:office:spreadsheet\"");  
          
writer.WriteLine("xmlns:html=\"http://www.w3.org/TR/REC-html40\">");  
          
writer.WriteLine("<DocumentProperties xmlns=\"urn:schemas-microsoft-com:office:office\">");  
          
writer.WriteLine("<LastAuthor>Automated Report Generator Example</LastAuthor>");  
          
writer.WriteLine(string.Format("<Created>{0}T{1}Z</Created>", DateTime.Now.ToString("yyyy-mm-dd"), DateTime.Now.ToString("HH:MM:SS")));  
          
writer.WriteLine(" <Company>51aspx.com</Company>");  
          
writer.WriteLine(" <Version>11.6408</Version>");  
          
writer.WriteLine("</DocumentProperties>");  
          
writer.WriteLine("<ExcelWorkbook xmlns=\"urn:schemas-microsoft-com:office:excel\">");  
          
writer.WriteLine("<WindowHeight>6195</WindowHeight>");  
          
writer.WriteLine(" <WindowWidth>18495</WindowWidth>");  
          
writer.WriteLine(" <WindowTopX>525</WindowTopX>");  
          
writer.WriteLine(" <WindowTopY>4260</WindowTopY>");  
          
writer.WriteLine(" <AcceptLabelsInFormulas/>");  
          
writer.WriteLine(" <ProtectStructure>True</ProtectStructure>");  
          
writer.WriteLine(" <ProtectWindows>False</ProtectWindows>");  
          
writer.WriteLine("</ExcelWorkbook>");  
          
//通過 ss:ID 和 ss:Name相當於html中style的類  
          
writer.WriteLine(" <Styles> ");  
          
writer.WriteLine(" <Style ss:ID='Default' ss:Name='Normal'> ");  
          
writer.WriteLine(" <Alignment ss:Vertical='Bottom'/> ");  
          
writer.WriteLine(" <Borders/> ");

方法四 用微軟的COM組件操作Excel。雖然可以很方便的操作單元格，並且能保留VBA代碼，它相當於直接打開一個EXCEL進程。

當初這個COM組件式給WinForm准備的，但在Web端有很多東西的支持不盡人意，例如無法用組件中的方法關閉Excel對象，

只能通過強制關閉Excel進程的方式(這其中還有很多問題，例如只能關閉當前打開的這個Excel的進程，否則會把其他用戶的Excel進程關閉)。在這里不推薦

方法五 用流的方式，把內容以Table的格式向Excel中放數據好處是可以生成格式豐富復雜的Excel，頁面無刷新

aspx部分

復制代碼代碼如下:

 
<asp:Button ID="hidExport" onClick="hidExport_Click()" Runat="server"></asp:Button>

aspx.cs部分

復制代碼代碼如下:

 
//內容很好理解，只需當成Table來拼字符串即可  
          
private string getExcelContent()  
          
{  
          
StringBuilder sb = new StringBuilder();  
          
sb.Append("<table borderColor='black' border='1' >");  
          
sb.Append("<thead><tr><th colSpan='2' bgColor='#ccfefe'>標題</th></tr>");  
          
sb.Append("<tr><th bgColor='#ccfefe'>號碼</th><th bgColor='#ccfefe'>名字</th></tr></thead>");  
          
sb.Append("<tbody>");  
          
sb.Append("<tr class='firstTR'><td bgcolor='#FF99CC'></td><td></td></tr>");  
          
sb.Append("<tr class='secondTR'><td></td><td bgcolor='lightskyblue'></td></tr>");  
          
sb.Append("</tbody></table>");  
          
return sb.ToString();  
          
}  
          
private void hidExport_Click(object sender, System.EventArgs e)  
          
{  
          
string content = getExcelContent();  
          
string css = ".firstTR td{color:blue;width:100px;}.secondTR td{color:blue;width:100px;}";  
          
string filename = "Test.xls";  
          
CommonTool.ExportToExcel(filename, content ,css);  
          
}

工具類CommonTool

復制代碼代碼如下:

 
public class CommonTool  
          
{  
          
/// <summary>  
          
/// 以流的形式，可以設置很豐富復雜的樣式  
          
/// </summary>  
          
/// <param name="content">Excel中內容(Table格式)</param>  
          
/// <param name="filename">文件名</param>  
          
/// <param name="cssText">樣式內容</param>  
          
public static void ExportToExcel(string filename, string content,string cssText)  
          
{  
          
var res = HttpContext.Current.Response;  
          
content = String.Format("<style type='text/css'>{0}</style>{1}",cssText,content);  
          
res.Clear();  
          
res.Buffer = true;  
          
res.Charset = "UTF-8";  
          
res.AddHeader("Content-Disposition", "attachment; filename=" + filename);  
          
res.ContentEncoding = System.Text.Encoding.GetEncoding("UTF-8");  
          
res.ContentType = "application/ms-excel;charset=UTF-8";  
          
res.Write(content);  
          
res.Flush();  
          
res.End();  
          
}  
          
}

這種方法比較靈活，而且可以通過選擇器來添加樣式，相當不錯。缺點就是需要將數據轉換成字符串。
