问题描述
限时送ChatGPT账号..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.但是,当我打开 xlsx 的文本文件时,我获得了整个页面的所有 html,而不仅仅是 gridview(这可能是 Excel 正在谈论的不可读内容).
Excel is telling me that there is unreadable data, and so after I say to try to recover the information, it shows the correct data. When I open the text file of the xlsx, though, I get all of the html for the entire page, instead of just the gridview (which is probably the unreadable content Excel is talking about).
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任何想法吗?在我尝试将 HTML 数据发送到 Excel 时遇到同样的问题后,有人建议使用 EPPlus,它发送的是整个页面,而不仅仅是 gridView.
Any ideas about what might be happening? Someone suggested using EPPlus after I had the same problems trying to send HTML data to Excel, and it was sending the entire page, instead of just the gridView.
谢谢
推荐答案
我缺少 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();
这篇关于使用 EPPlus,我试图将 gridview 导出到 Excel 工作表的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持IT屋!
