我有这个代码，但为此你需要包括Excel Com组件
在项目中添加Microsoft.Office.Interop.Excel.dll引用将为您完成任务。
using Excel = Microsoft.Office.Interop.Excel; public static bool ExportDataTableToExcel(DataTable dt, string filepath) { Excel.Application oXL; Excel.Workbook oWB; Excel.Worksheet oSheet; Excel.Range oRange; try { // Start Excel and get Application object. oXL = new Excel.Application(); // Set some properties oXL.Visible = true; oXL.DisplayAlerts = false; // Get a new workbook. oWB = oXL.Workbooks.Add(Missing.Value); // Get the Active sheet oSheet = (Excel.Worksheet)oWB.ActiveSheet; oSheet.Name = "Data"; int rowCount = 1; foreach (DataRow dr in dt.Rows) { rowCount += 1; for (int i = 1; i < dt.Columns.Count + 1; i++) { // Add the header the first time through if (rowCount == 2) { oSheet.Cells[1, i] = dt.Columns[i - 1].ColumnName; } oSheet.Cells[rowCount, i] = dr[i - 1].ToString(); } } // Resize the columns oRange = oSheet.get_Range(oSheet.Cells[1, 1], oSheet.Cells[rowCount, dt.Columns.Count]); oRange.EntireColumn.AutoFit(); // Save the sheet and close oSheet = null; oRange = null; oWB.SaveAs(filepath, Excel.XlFileFormat.xlWorkbookNormal, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Excel.XlSaveAsAccessMode.xlExclusive, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value); oWB.Close(Missing.Value, Missing.Value, Missing.Value); oWB = null; oXL.Quit(); } catch { throw; } finally { // Clean up // NOTE: When in release mode, this does the trick GC.WaitForPendingFinalizers(); GC.Collect(); GC.WaitForPendingFinalizers(); GC.Collect(); } return true; }
我会推荐EPPlus – 这个解决方案不需要COM也不需要互操作，而且非常快。 非常适合Web场景。
http://nuget.org/packages/EPPlus
private void DumpExcel(DataTable tbl) { using (ExcelPackage pck = new ExcelPackage()) { //Create the worksheet ExcelWorksheet ws = pck.Workbook.Worksheets.Add("Demo"); //Load the datatable into the sheet, starting from cell A1. Print the column names on row 1 ws.Cells["A1"].LoadFromDataTable(tbl, true); //Format the header for column 1-3 using (ExcelRange rng = ws.Cells["A1:C1"]) { rng.Style.Font.Bold = true; rng.Style.Fill.PatternType = ExcelFillStyle.Solid; //Set Pattern for the background to Solid rng.Style.Fill.BackgroundColor.SetColor(Color.FromArgb(79, 129, 189)); //Set color to dark blue rng.Style.Font.Color.SetColor(Color.White); } //Example how to Format Column 1 as numeric using (ExcelRange col = ws.Cells[2, 1, 2 + tbl.Rows.Count, 1]) { col.Style.Numberformat.Format = "#,##0.00"; col.Style.HorizontalAlignment = ExcelHorizontalAlignment.Right; } //Write it back to the client Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"; Response.AddHeader("content-disposition", "attachment; filename=ExcelDemo.xlsx"); Response.BinaryWrite(pck.GetAsByteArray()); } } } }
您可以使用
using Microsoft.Office.Interop.Excel;
使用excel文档“本机”…

但是，如果您使用的是SQL SERVER，大多数常见的报告生成器/设计器都可以轻松导出到excel，还可以检查Reporting Services
以防其他人使用所选解决方案并遇到“对象不包含get_Range的定义”exception。 我在这里找到了解决方案： 工作表get_Range抛出exception 。 我希望这会节省你的时间。
