一個將datagrid控件內容輸出到excel文件的demo.

生成EXCEL文件#region 生成EXCEL文件public void setToExcel(){// Response.Clear(); // Response.Buffer= true; // Response.Charset="utf-8";　　 if (eformsn.Text=="") { DataGrid1.Visible=false; Label1.Text="要匯入EXCEL，請先輸入申請單號!"; Label1.Visible=true; } else { dl.DataSource=DB("query", "select * from msi_eol_list_line where eformsn="+eformsn.Text+" order by eformsn").Tables[0].DefaultView; dl.DataBind();

//下面這行很重要，attachment 參數表示作為附件下載，您可以改成online在線打開 //filename=FileFlow.xls 指定輸出文件的名稱，注意其擴展名和指定文件類型相符，可以為：.doc .xls .txt .htm　　

Response.AppendHeader("Content-Disposition","attachment;filename=EOL_"+eformsn.Text+".xls"); Response.ContentEncoding=System.Text.Encoding.GetEncoding("utf-8");　

//Response.ContentType指定文件類型 可以為application/ms-excel,application/ms-word ,application/ms-txt,application/ms-html或其他瀏覽器可直接支持文檔　 Response.ContentType = "application/ms-excel"; dl.EnableViewState = false;　

System.IO.StringWriter oStringWriter = new System.IO.StringWriter(); System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);

//將目標數據綁定到輸入流輸出　　 //this 表示輸出本頁，你也可以綁定datagrid,或其他支持obj.RenderControl()屬性的控件　　 dl.RenderControl(oHtmlTextWriter); //this.DataBind.RenderControl(oHtmlTextWriter); Response.Write(oStringWriter.ToString()); Response.End(); }}#endregion
