使用EPPlus，我試圖將一個gridview導出到一個Excel工作表

Question

Excel告訴我有不可讀的數據，所以在我說要嘗試恢復信息之後，它會顯示正確的數據。但是，當我打開xlsx的文本文件時，我得到了整個頁面的所有html，而不是僅僅是gridview（這可能是Excel討論的不可讀內容）。

這裏是我的代碼：

public void ExcelDownload(object sender, EventArgs e) 
    { 
     DataSet _MailingListUsers = db.GetMailingList(); 
     DataTable mailTable = _MailingListUsers.Tables[0]; 

     DumpExcel(mailTable); 

    } 

    private void DumpExcel(DataTable tbl) 
    { 
     using (ExcelPackage pck = new ExcelPackage()) 
     { 
      //Create the worksheet 
      ExcelWorksheet ws = pck.Workbook.Worksheets.Add("Mailing List"); 

      //Load the datatable into the sheet, starting from cell A1. Print the column names on row 1 
      ws.Cells["A2"].LoadFromDataTable(tbl, false); 

      //Header Titles 
      ws.Cells["A1"].Value = "Employee Name"; 
      ws.Cells["B1"].Value = "Email Address"; 
      ws.Cells["C1"].Value = "Phone"; 
      ws.Cells["D1"].Value = "Business Unit"; 
      ws.Cells["E1"].Value = "Site"; 

      ws.Cells["A1"].AutoFitColumns(); 

      //Format the header for column 1-3 
      using (ExcelRange rng = ws.Cells["A1:E1"]) 
      { 
       rng.Style.Font.Bold = true; 
       //Set Pattern for the background to Solid 
       rng.Style.Fill.PatternType = ExcelFillStyle.Solid;  
       //Set color to dark blue 
       rng.Style.Fill.BackgroundColor.SetColor(System.Drawing.Color.FromArgb(79, 129, 189)); 
       rng.Style.Font.Color.SetColor(System.Drawing.Color.White); 
      } 


      //Write it back to the client 
      Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"; 
      Response.AddHeader("content-disposition", "attachment; filename=MailingList.xlsx"); 
      Response.BinaryWrite(pck.GetAsByteArray()); 
     } 
    } 

什麼可能發生的任何想法？在嘗試將HTML數據發送到Excel時遇到同樣的問題後，有人建議使用EPPlus，並且它發送的是整個頁面，而不僅僅是gridView。

感謝

我錯過了Response.Clear()和Response.End()：

try { 
    var pck = new OfficeOpenXml.ExcelPackage(); 
    var ws = pck.Workbook.Worksheets.Add("Mailing List"); 
    ws.Cells["A2"].LoadFromDataTable(tbl, false); 
    Response.Clear(); 
    Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"; 
    Response.AddHeader("content-disposition", "attachment; filename=MailingList.xlsx"); 
    Response.BinaryWrite(pck.GetAsByteArray()); 
} catch (Exception ex) { 
    //log error 
} 
Response.End();
