问题描述
亲爱的朋友，
我需要将折叠gridview导出为excel。我有这个代码中的问题。找不到类型或命名空间XLWorkbook。这里有什么问题。
DataTable dt = new DataTable（GridView_Data）;
GridView gvOrders =（GridView）gvCustomers.Rows [1] .FindControl（gvOrders）;
foreach（gvCustomers.HeaderRow.Cells中的TableCell单元格）
{
dt.Columns .Add（cell.Text）;
}
foreach（gvOrders.HeaderRow.Cells中的TableCell单元格）
{
dt.Columns.Add（cell.Text）;
}
dt.Columns.RemoveAt（0）;
foreach（ gvCustomers.Rows中的GridViewRow行）
{
GridView gvOrderscell =（row.FindControl（gvOrders）as GridView）;
for（ int j = 0; j< gvOrderscell.Rows.Count; j ++）
{
dt。 Rows.Add（row.Cells [1] .Text，row.Cells [2] .Text，gvOrderscell.Rows [j] .Cells [0] .Text，gvOrderscell.Rows [j] .Cells [1] .Text） ;
}
}
使用（XLWorkbook wb =新XLWorkbook（））
{
wb.Worksheets.Add（dt）;
Response.Clear（）;
Response.Buffer = true;
Response.Charset =;
Response.ContentType =application / vnd.openxmlformats-officedocument.spreadsheetml.sheet;
响应。 AddHeader（content-disposition，attachment; filename = GridView.xlsx）;
使用（MemoryStream MyMemoryStream = new MemoryStream（））
{
wb.SaveAs（MyMemoryStream）;
MyMemoryStream.WriteTo（Response.OutputStream） ;
Response.Flush（）;
Response.End（）;
}
}
