Question

我的代码运行一个存储过程，为每个客户检索多个报告。所有这些报告都在excel的同一张表中查看。有人可以告诉我如何在多个Excel工作表上查看我的报表，而不仅仅是1？

 using (SqlCommand sqlCmd = new SqlCommand("databases.dbo.SP_GetAll_Reports",    connection))
        {
            sqlCmd.CommandType = CommandType.StoredProcedure;
            sqlCmd.Parameters.AddWithValue("@customerName", SqlDbType.NVarChar).Value = custName;
            using (SqlDataAdapter sqlDa = new SqlDataAdapter(sqlCmd))
            {
                Session["TaskTable"] = dt;
                sqlDa.Fill(dt);
                if (dt.Tables.Count > 0)
                {
                     StringWriter sw = new StringWriter();
                    foreach(DataTable table in dt.Tables)
                    {
                         HtmlTextWriter hw = new HtmlTextWriter(sw);
                        DataGrid dg = new DataGrid();
                        dg.DataSource = table;
                        dg.DataBind();
                        dg.RenderControl(hw);
                    }
                    Response.Clear();
                    Response.AddHeader("content-disposition", "attachchment;       filename=Report_Accounting.xls");
                    Response.Charset = "";
                    Response.ContentType = "application/vnd.xls";
                    Response.Write(sw.ToString());
                    Response.End();
                }

 {
     sqlCmd.CommandType = CommandType.StoredProcedure;
     sqlCmd.Parameters.AddWithValue("@customerName", SqlDbType.NVarChar).Value = custName;
     using (SqlDataAdapter sqlDa = new SqlDataAdapter(sqlCmd))
     {
         Session["TaskTable"] = dt;
         sqlDa.Fill(dt);
         if (dt.Tables.Count > 0)
         {
             MemoryStream ms = new MemoryStream();
             int i=1;
             using (ExcelPackage package = new ExcelPackage(ms))
             {
                 foreach(DataTable table in dt.Tables)
                 {
                     ExcelWorksheet worksheet = package.Workbook.Worksheets.Add("Sheet"+i++);
                     worksheet.Cell["A1"].LoadFromDataTable(table, true); 
                 }
                 Response.Clear(); 
                 package.SaveAs(Response.OutputStream);
                 Response.AddHeader("content-disposition", "attachchment;       filename=Report_Accounting.xls");
                 Response.Charset = "";
                 Response.ContentType = "application/vnd.xls";
                 Response.End();
             }
         }
     }
 }
