使用封闭的xml将数据表转换为excel（xls或xlsx）。当您提供使用下载功能时，这将帮助您。并且您正在使用sql server并在excel中向用户提供数据。

Answer 1

从nuget下载closedxml。

using(XLWorkbook wb = new XLWorkbook()) {  
            wb.Worksheets.Add(dt);  
            wb.Style.Alignment.Horizontal = XLAlignmentHorizontalValues.Center;  
            wb.Style.Font.Bold = true;  

            Response.Clear();  
            Response.Buffer = true;  
            Response.Charset = "";  
            Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";  
            Response.AddHeader("content-disposition", "attachment;filename= EmployeeReport.xlsx");  

            using(MemoryStream MyMemoryStream = new MemoryStream()) {  
                wb.SaveAs(MyMemoryStream);  
                MyMemoryStream.WriteTo(Response.OutputStream);  
                Response.Flush();  
                Response.End();  
            }

以下是另一种方法，使用GemBox.Spreadsheet：

ExcelFile ef = new ExcelFile();
ef.Styles.Normal.HorizontalAlignment = HorizontalAlignmentStyle.Center;
ef.Styles.Normal.Font.Weight = ExcelFont.BoldWeight;

ExcelWorksheet ws = ef.Worksheets.Add("Sheet1");
ws.InsertDataTable(dt);

ef.Save(Response, "EmployeeReport.xlsx");
