使用到 Aspose.Cells 插件，整理一下。

一：新建解決方案，目錄如下

　　目錄說明：

　　　　Program.cs - 入口類

　　　　ExcelGenerator.cs - Aspose.Cells 操作類

　　　　Aspose.Cell.dll - 基礎dll【文件見文章底部源代碼內】

　　　　License.lic - Aspose.Cells 破解證書【文件見文章底部源代碼內】

　　　　　　ps：由於 Aspose.Cells 插件是收費插件，需要在使用插件前，設置一下許可證，否則在生成的Excel 中會出現一個名叫 Evaluation Warning 的 Sheet.如圖所示：

二：Aspose.Cells 操作

　　2.1 引入 Aspose.Cell.dll

　　2.2 設置 Aspose.Cell.dll 證書 License.lic

　　　　2.2.1 設置證書。我一般都寫在生成Excel類的構造函數中了。文件路徑要和證書的位置保持一致

Excel.License l = new Excel.License();
l.SetLicense("Aid/License.lic");

　　　　2.2.2 修改證書屬性。在解決方案中，右擊 License.lic選擇屬性,修改 Copy to Ouput Directory 屬性為 Copy always

　　2.3 打開現有Execl 模板

//模板文件路徑
string Template_File_Path = @".\Template\Template.xlsx";

//  打開 Excel 模板
Workbook CurrentWorkbook = File.Exists(Template_File_Path) ? new Workbook(Template_File_Path) : new Workbook();

//  打開第一個sheet
Worksheet DetailSheet = CurrentWorkbook.Worksheets[0];

　　2.4 寫入數據

　　　　2.4.1 填寫數據到指定單元格

 // 比如要在 A1 位置寫入 Demo這個值

Cell itemCell = DetailSheet.Cells["A1"];

itemCell.PutValue("Demo");

　　　　2.4.2 把DataTable寫入到Excel

//  獲取 Table 數據
DataTable dt = GetData();
            
//  寫入數據的起始位置
string cell_start_region = "C1";
//  獲得開始位置的行號                    
int startRow = DetailSheet.Cells[cell_start_region].Row;
//  獲得開始位置的列號  
int startColumn = DetailSheet.Cells[cell_start_region].Column;  

//  寫入Excel。參數說明，直接查閱文章底部文檔鏈接
DetailSheet.Cells.ImportDataTable(dt, false, startRow, startColumn, true, true);

　　2.5 保存Excel

//  設置執行公式計算 - 如果代碼中用到公式，需要設置計算公式，導出的報表中，公式才會自動計算
CurrentWorkbook.CalculateFormula(true);

//  生成的文件名稱
string ReportFileName = string.Format("Excel_{0}.xlsx", DateTime.Now.ToString("yyyy-MM-dd"));

//  保存文件
CurrentWorkbook.Save(@".\Excel\" + ReportFileName, SaveFormat.Xlsx);

/新建工作簿
Workbook workbook = new Workbook(); //工作簿
Worksheet sheet = workbook.Worksheets[0]; //工作表
Cells cells = sheet.Cells;//單元格
 
sheet.Protect(ProtectionType.All, "123123", "");//保護工作表
sheet.Protection.IsSelectingLockedCellsAllowed = false;//設置只能選擇解鎖單元格
sheet.Protection.IsFormattingColumnsAllowed = true;//設置可以調整列
sheet.Protection.IsFormattingRowsAllowed = true;//設置可以調整行
 
Style style1 = workbook.Styles[workbook.Styles.Add()];//新增樣式
style1.HorizontalAlignment = TextAlignmentType.Center;//文字居中
style1.Font.Name = "宋體";//文字字體
style1.Font.Size = 22;//文字大小
style1.IsLocked = false;//單元格解鎖
style1.Font.IsBold = true;//粗體
style1.ForegroundColor = Color.FromArgb(0xaa, 0xcc, 0xbb);//設置背景色
style1.Pattern = BackgroundType.Solid; //設置背景樣式
style1.IsTextWrapped = true;//單元格內容自動換行
style1.Borders[BorderType.LeftBorder].LineStyle = CellBorderType.Thin; //應用邊界線 左邊界線
style1.Borders[BorderType.RightBorder].LineStyle = CellBorderType.Thin; //應用邊界線 右邊界線
style1.Borders[BorderType.TopBorder].LineStyle = CellBorderType.Thin; //應用邊界線 上邊界線

style1.Borders[BorderType.BottomBorder].LineStyle = CellBorderType.Thin; //應用邊界線下邊界線

cells.Merge(0, 0, 1, 5);//合並單元格 cells[0, 0].PutValue("內容");//填寫內容 cells[0, 0].SetStyle(style1);//給單元格關聯樣式 cells.SetRowHeight(0, 20);//設置行高 cells.SetColumnWidth(1, 30);//設置列寬 cells[1, 0].Formula = "=AVERAGE(B1:E1)";//給單元格設置計算公式

//從Cells[0,0]開始創建一個2行3列的Range Range range = ws.Cells.CreateRange(0, 0, 2, 3); Cell cell = range[0, 0]; cell.Style.Font = 9; range.Style = style; range.Merge();

注意Range不能直接設置Style.必須先定義style再將style賦給Style.其他設置和Cell基本一致. Range的Style會覆蓋Cell定義的Style.另外必須先賦值再傳Style.否則可能不生效.

sheet.Cells[0,0].PutValue(1); sheet.Cells[1,0].PutValue(20); sheet.Cells[2,0].Formula="SUM(A1:B1)"; sheet.CalculateFormula(true); Save Excel文件的時候必須調用CalculateFormula方法計算結果.

//********************************************************************************

1.創建execl（不需要服務器或者客戶端安裝office）

public void DCExexl(DataTable dt) { Workbook wb = new Workbook(); Worksheet ws = wb.Worksheets[0]; Cells cell = ws.Cells;

cell[0, 0].PutValue("ID");//添加數據到第0行和第0列

cell.SetRowHeight(0, 0);設置行高

Aspose.Cells.Style style1 = wb.Styles[wb.Styles.Add()]; style1.HorizontalAlignment = TextAlignmentType.Right;//文字居中

style1.Font.Name = "宋體"; style1.Font.IsBold = true;//設置粗體 style1.Font.Size = 12;//設置字體大小

cell[0, 0].SetStyle(style1);

cell.SetColumnWidth(0, 10.00);//列寬

Range range = cell.CreateRange(0, 0, 1, 1);//合並單元格 range.Merge();

string FileName = DateTime.Now.ToString("yyyyMMddHHmmss") + ".xls"; HttpResponse response = Page.Response; response.Buffer = true; response.Charset = "utf-8"; response.AppendHeader("Content-Disposition", "attachment;filename=" + FileName); response.ContentEncoding = System.Text.Encoding.UTF8; response.ContentType = "application/ms-excel"; response.BinaryWrite(wb.SaveToStream().ToArray()); response.End();

}

2.讀取execl

public DataTable GetDataTable(string path) { Workbook workbook = new Workbook(); workbook.Open(path); Cells cells = workbook.Worksheets[0].Cells; DataTable dt = new DataTable(); bool d = true;//防止表頭重復加載 for (int i = 0; i < cells.MaxDataRow + 1; i++) { DataRow row = dt.NewRow(); for (int j = 0; j < cells.MaxDataColumn + 1; j++) { if (d) { dt.Columns.Add(cells[0, j].StringValue.Trim()); } row[j] = cells[i + 1, j].StringValue.Trim(); } dt.Rows.Add(row); d = false; } return dt; }

//*******************************************************************************

讀Excel

[csharp] view plain copy

Aspose.Cells.Workbook wk = new Aspose.Cells.Workbook();
wk.Open(file);//打開Excel文檔
Worksheet sht = wk.Worksheets[0];//查看文檔的sheet0內容
Cells cells = sht.Cells;//獲取sheet0的所有單元格
if (sht==null)
{
return false;
}
int rowCount = cells.MaxDataRow+1;//當Excel沒有一行數據時，讀取到的cells.MaxDataRow=-1，當有一行數據時cells.MaxDataRow=0 MaxDataRow：包含數據的單元格的最大行索引
int cellCount = cells.MaxDataColumn + 1;//當Excel沒有一行數據時，讀取到的cells.MaxDataRow=-1，當有一行數據時cells.MaxDataRow=0 MaxDataRow：包含數據的單元格的最大列索引
string title = cells[j, k].Value.ToString();//獲取第j行k列單元格的內容

Aspose.Cells.Workbook wk = new Aspose.Cells.Workbook();
wk.Open(file); //打開Excel文檔
Worksheet sht = wk.Worksheets[ 0];//查看文檔的sheet0內容
Cells cells = sht.Cells; //獲取sheet0的所有單元格
if (sht==null)
{
return false;
}
int rowCount = cells.MaxDataRow+1;//當Excel沒有一行數據時，讀取到的cells.MaxDataRow=-1，當有一行數據時cells.MaxDataRow=0 MaxDataRow：包含數據的單元格的最大行索引
int cellCount = cells.MaxDataColumn + 1;//當Excel沒有一行數據時，讀取到的cells.MaxDataRow=-1，當有一行數據時cells.MaxDataRow=0 MaxDataRow：包含數據的單元格的最大列索引
string title = cells[j, k].Value.ToString();//獲取第j行k列單元格的內容

寫Excel

[csharp] view plain copy

print ?

int _BugNoColumn = cells.MaxDataColumn+1;;//獲取最后單元格的內容
cells.InsertColumn(_BugNoColumn);//在最后單元格的后一列插入一列
Cell cell = cells[0, _BugNoColumn];//獲取插入的那一列的第一行的單元格
cell.PutValue("abc");//設置單元格的內容為"abc"

基於Aspose.Cells.dll 封裝了對於導出的Excel的各種樣式設置，內容填充操作，目前支持邊框樣式，顏色，字體，合並單元格等操作,簡化Aspose.Cells.dll的使用

調用示例

/// ---------->Clom Y

/// |
/// |
/// \/ Row X
static void Main(string[] args)
{
object[] clom = { "列名1", "列名2", "列名3" };

String filename = "text.xlsx";
//列標題樣式
CellStyle Styleclom = new CellStyle();
Styleclom .AllBorder = Aspose.Cells.CellBorderType.Thin;
Styleclom .ForegroundColor = Color.Yellow;
Styleclom .IsBold = true;
//行標題樣式
CellStyle Stylerow = new CellStyle();
Stylerow .AllBorder = Aspose.Cells.CellBorderType.Thin;
Stylerow .ForegroundColor = Color.ForestGreen;
Stylerow .IsBold = true;
//單元格樣式
CellStyle Stylebody = new CellStyle();
Stylebody .AllBorder = Aspose.Cells.CellBorderType.Medium;
Stylebody .ForegroundColor = Color.LightBlue;
Stylebody .IsBold = true;
Stylebody .IsItalic = true;
//將樣式和內容填充到模板中
ExcelFormat eformat = new ExcelFormat();
eformat .SavePath = filename;
eformat .ColumnsSize = 20;
eformat .RowsSize = 20;
//直接插入標題
//eformat.InsertTitle(clom.ToList(), Styleclom, ExcelFormat.TitleType.列標題);
//eformat.InsertTitle(row.ToList(), Stylerow, ExcelFormat.TitleType.行標題);
eformat .InsertCellRow(new CellRow(1, 4, 0, clom.ToList()), Stylerow);
eformat .InsertCellColm(new CellColm(1, 5, 0, row.ToList()), Styleclom);
for (int i = 0; i < clom.Length; i++)
{
for (int j = 0; j < row.Length; j++)
{
SCell scell = new SCell();
scell .Txt_Obj = Convert.ToString(row[j]) + Convert.ToString(row[i]);
scell .X = j + 1;
scell .Y = i + 1;
scell .CStyle = Stylebody;

}
}
//向Excel中寫入數據
ExcelMethod .InsertData(eformat, true);
Console .WriteLine("完畢");
Console .ReadLine();
}

導出例子
這里寫圖片描述

GitHub地址

2017/11/15更新后不再對所謂的標題行標題列作區分(在ExcelFormat對象中只保留SCells屬性，即可配置樣式的單元格集合。除此之外，新增了數據行，數據列，數據區塊的概念，方便一組規則且具有相同樣式的數據區塊插入。為確保配置樣式和插入的靈活性，所有的單元格最終匯總到SCells中等待寫入)

C# 讀寫Excel的一些方法,Aspose.Cells.dll

需求：現有2個Excel，一個7000，一個20W，7000在20W是完全存在的。現要分離20W的，拆分成19W3和7000。

條件：兩個Excel都有“登錄名”，然后用“登錄名”去關聯2個Excel

引用：Aspose.Cells.dll

public void Excel()
{ 
    //獲取第一個Excel,20W
    string filePath = AppDomain.CurrentDomain.BaseDirectory.Replace("\\", "/") + "daochu/測試20W.xlsx";
    System.Data.DataTable table = GetTableFromExcel("sheet1", filePath);

    //克隆
    System.Data.DataTable table20W_new = table.Clone();
    System.Data.DataTable table7000_new = table.Clone();    

    //獲取第二個Excel,7000
    string filePath_7000 = AppDomain.CurrentDomain.BaseDirectory.Replace("\\", "/") + "daochu/測試7000.xls";
    System.Data.DataTable table_7000 = GetTableFromExcel("sheet1", filePath_7000);

    //循環20W人中的挑出來
    for (int i = 0; i < table.Rows.Count; ++i)
    {
        //20W
        DataRow dateRow = table.Rows[i];
        string login_name = dateRow["登錄名"].ToString();

        //7000
        DataRow[] drss = table_7000.Select("登錄名 = '" + login_name + "'");
　　　　 
        if (drss.Length > 0)
        {
            table7000_new.ImportRow(dateRow);
        }
        else
        {
            table20W_new.ImportRow(dateRow);
        }
    }
    //導出Excel

Aspose.Cells.dll（我們就叫工具包吧，可以從網上下載。關於它的操作我在“Aspose.Cells操作說明中文版下載 Aspose C # 導出Excel 實例”一文中的說。這里你暫時也可不理會它。）
即使沒有安裝office也能用噢，這是一個好強的大工具。

很多時候輸出的數據排序或者顯示的列並不一定和DataTable得到的列排序數據完全一致，那么我們可以簡單處理一下：比如把上面的

引用內容
