Excel告诉我有不可读的数据,所以在我选择尝试恢复信息后,它会显示正确的数据。但是当我打开xlsx的文本文件时,我得到整个页面的所有HTML代码,而不仅仅是网格视图(这可能就是Excel提到的不可读内容)。
以下是我的代码:
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());
}
}
有什么想法可能是发生了什么?有人建议在我尝试将HTML数据发送到Excel并且它发送整个页面而不是只有gridView后使用EPPlus。
谢谢。
