先把代碼貼出來:
public void Print() { //接收需要導出的數據 List<實體類名稱> list = db.findAll<實體類名稱>(); //命名導出表格的StringBuilder變量 StringBuilder sHtml = new StringBuilder(string.Empty); //打印表頭 sHtml.Append("<table border=\"1\" width=\"100%\">"); sHtml.Append("<tr height=\"40\"><td colspan=\"5\" align=\"center\" style='font-size:24px'><b>XXXXXXX報價表" + "</b></td></tr>"); //打印列名 sHtml.Append("<tr height=\"20\" align=\"center\" style='background-color:#CD0000'><td>編號</td><td>商品名稱</td><td>市場價</td><td>VIP價格</td><td>說明</td></tr>"); //循環讀取List集合 for (int i = 0; i < list.Count; i++) { sHtml.Append("<tr height=\"20\" align=\"left\"><td style='background-color:#8DEEEE'>" + list[i].Id + "</td><td>" + list[i].Title + "</td><td style='background-color:#8DEEEE'>¥" + list[i].SalePrice + "</td><td style='color:#F00;background-color:#8DEEEE;'>¥" + list[i].VipPrice + "</td><td>" + list[i].Summary + "</td></tr>"); } //打印表尾 sHtml.Append("<tr height=\"40\"><td align=\"center\" colspan=\"5\" style='background-color:#CD0000;font-size:24px'><b>XXXXXXXX</a> </b></td></tr>"); sHtml.Append("</table>"); //調用輸出Excel表的方法 ExportToExcel("application/ms-excel", "XXXXXX報價表.xls", sHtml.ToString()); }

1 //輸入HTTP頭,然后把指定的流輸出到指定的文件名,然后指定文件類型 2 public void ExportToExcel(string FileType, string FileName, string ExcelContent) 3 { 4 System.Web.HttpContext.Current.Response.ContentType = FileType; 5 System.Web.HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.UTF8; 6 System.Web.HttpContext.Current.Response.Charset = "utf-8"; 7 System.Web.HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(FileName, System.Text.Encoding.UTF8).ToString()); 8 9 System.IO.StringWriter tw = new System.IO.StringWriter(); 10 System.Web.HttpContext.Current.Response.Output.Write(ExcelContent.ToString()); 11 /*亂碼BUG修改 20140505*/ 12 //如果采用以上代碼導出時出現內容亂碼,可將以下所注釋的代碼覆蓋掉上面【System.Web.HttpContext.Current.Response.Output.Write(ExcelContent.ToString());】即可實現。 13 //System.Web.HttpContext.Current.Response.Write("<meta http-equiv=\"content-type\" content=\"application/ms-excel; charset=utf-8\"/>" + ExcelContent.ToString()); 14 System.Web.HttpContext.Current.Response.Flush(); 15 System.Web.HttpContext.Current.Response.End(); 16 }
