C# 如何将两个GridView导出到一个MS Excel文件中的两个单独的图纸中？

如何通过单击1按钮将两个gridviews GridView1和GridView2导出到一个MS Excel文件中的两个单独的工作表中？目前，我只能将1个gridview导出到文件名与工作表名称相同的Excel工作表。但我想将两个GridView分成两个单独的图纸，我希望图纸名称由我自己定义/设置。谢谢

public void ExportGridToExcel()
{
      Response.Clear();
      Response.Buffer = true;
      Response.ClearContent();
      Response.ClearHeaders();
      Response.Charset = "";

      string FileName ="Export"+DateTime.Now+".xls";

      StringWriter strwritter = new StringWriter();
      HtmlTextWriter htmltextwrtter = new HtmlTextWriter(strwritter);

      Response.Cache.SetCacheability(HttpCacheability.NoCache);
      Response.ContentType = "application/vnd.ms-excel";
      Response.AddHeader("Content-Disposition","attachment;filename=" + FileName);

      GridView1.GridLines = GridLines.Both;
      GridView1.HeaderStyle.Font.Bold = true;
      GridView1.RenderControl(htmltextwrtter);

      Response.Write(strwritter.ToString());
      Response.End();
}

//编辑我的答案，因为只有一个导出按钮： 看看：

首先添加以下名称空间：

using Excel = Microsoft.Office.Interop.Excel;
using System.Reflection;
using System.IO;

因此，基本上，您应该拥有或继续使用2个DataTable来绑定到2个GridView:dt1和dt2

创建一个数据集并向其中添加2个数据表

DataSet dataset = new DataSet();
        dataset.Tables.Add(dt1);
        dataset.Tables.Add(dt2);

然后

您需要修改代码，以便在excel文件中创建工作表，手动将数据从网格复制到excel文件，并将此代码创建为一个函数，该函数采用网格、sheetname和sheetid，如1，2等作为参数，然后在button click事件中调用它两次，一次用于grid1，一次用于grid2，分别使用不同的SheetName和sheet ID 1和2。该函数的代码如下所示

在button click事件中编写这两行代码，然后通过将excel应用程序和工作簿作为参数传递给每个网格调用函数两次

     // creating Excel Application
     Microsoft.Office.Interop.Excel._Application app  = new Microsoft.Office.Interop.Excel.Application();

    // creating new WorkBook within Excel application
    Microsoft.Office.Interop.Excel._Workbook workbook =  app.Workbooks.Add(Type.Missing);

 public void ExportToExcel(Microsoft.Office.Interop.Excel._Application app, Microsoft.Office.Interop.Excel._Workbook workbook,GridView gridview,string SheetName,int sheetid)
 {  


        // creating new Excelsheet in workbook
         Microsoft.Office.Interop.Excel._Worksheet worksheet = null;                   

       // see the excel sheet behind the program
        app.Visible = true;

       // get the reference of first sheet. By default its name is Sheet1.
       // store its reference to worksheet
        worksheet = workbook.Sheets["Sheet"+ sheetid];
        worksheet = workbook.ActiveSheet;

        // changing the name of active sheet
        worksheet.Name = sheetname; 

        // storing header part in Excel
        for(int i=1;i<gridview.Columns.Count+1;i++)
        {
              worksheet.Cells[1, i] = gridview.Columns[i-1].HeaderText;
        }



        // storing Each row and column value to excel sheet
        for (int i=0; i < gridview.Rows.Count-1 ; i++)
        {
            for(int j=0;j<gridview.Columns.Count;j++)
            {
                worksheet.Cells[i + 2, j + 1] = gridview.Rows[i].Cells[j].Value.ToString();
            }
        }


        // save the application
        workbook.SaveAs("c:\\output.xls",Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive , Type.Missing, Type.Missing, Type.Missing, Type.Missing);

        // Exit from the application
      app.Quit();
    }

我建议您使用EP Plus之类的库来执行此操作。您好，只有一个导出按钮。我想将多个gridview导出到一个excel，因此我相信您的代码将通过两次调用导出到两个单独的excel。请告诉我谢谢你。我编辑了我的答案。希望这能解决问题。我已经添加了Microsoft.Offfice.Interop.Excel作为引用，但其中一个DataGridView中仍然存在错误，即下划线缺少类型或命名空间缺少引用错误。请告知，请提供获取错误的确切行以及错误消息Public void ExportToExcelMicrosoft.Office.Interop.Excel.\u应用程序应用程序，Microsoft.Office.Interop.Excel.\u工作簿，DataGridView gridview，字符串SheetName，int sheetid

currentSheet.Name = "your sheet name"
