使用EPPlus，我正在尝试将网格视图导出到Excel工作表

Excel告诉我有不可读的数据，所以在我说尝试恢复信息后，它显示了正确的数据。然而，当我打开xlsx的文本文件时，我会得到整个页面的所有html，而不仅仅是gridview（这可能是Excel所说的不可读内容）。

这是我的代码：

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());
        }
    }

对可能发生的事情有什么想法吗？有人建议使用EPPlus，因为我在尝试将HTML数据发送到Excel时遇到了同样的问题，它发送的是整个页面，而不仅仅是gridView。

感谢

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();
