导出3个网格视图，可以分为3个不同的工作表

从我的网站，我有一个button，调用一个方法，然后生成报告excel。 代码工作。 问题是代码在同一个选项卡上显示所有gridviews（有3个）。 我可以添加什么代码，以便当我点击button时，它将下载文档，但每个gridview显示在其单独的选项卡上。 标签名称将是前1，前2和前3。为了澄清，现在所有的gridviews都显示在前1个标签上，我需要制作2个标签（前2和前3），并把gridview2在顶部2选项卡和顶部3选项卡上的gridview3。

using System; using System.Configuration; using System.Linq; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.HtmlControls; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Xml.Linq; using System.Data; using System.Data.SqlClient; using System.Collections; using System.Text; using System.IO; public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { DataSet dataSet = new DataSet(); SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["ISALog1ConnectionString"].ToString()); SqlCommand cmd = new SqlCommand("exec ProxyReport", conn); cmd.CommandTimeout = 200; SqlDataAdapter ad = new SqlDataAdapter(cmd); ad.Fill(dataSet); GridView1.DataSource = dataSet.Tables[0]; GridView1.DataBind(); GridView2.DataSource = dataSet.Tables[1]; GridView2.DataBind(); GridView3.DataSource = dataSet.Tables[2]; GridView3.DataBind(); } protected void Button1_Click(object sender, EventArgs e) { string attachment = "attachment; filename=Top 1.xls"; Response.ClearContent(); Response.AddHeader("content-disposition", attachment); Response.Cache.SetCacheability(HttpCacheability.NoCache); Response.ContentType = "application/ms-excel"; StringWriter sw = new StringWriter(); HtmlTextWriter htw = new HtmlTextWriter(sw); GridView1.RenderControl(htw); GridView2.RenderControl(htw); GridView3.RenderControl(htw); Response.Write(sw.ToString()); Response.End(); } public override void VerifyRenderingInServerForm(Control control) { } }

是的，您需要从codeplex中添加EPPlus： http ://epplus.codeplex.com/，然后将其添加到您的代码中。 您可以使用它来添加任意数量的工作表：

  using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Data; using System.Data.SqlClient; using System.IO; using OfficeOpenXml; using System.Configuration; public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } protected void Button1_Click(object sender, EventArgs e) { GetExcel ge = new GetExcel(); ge.ProcessRequest(HttpContext.Current); } public class GetExcel : IHttpHandler { public void ProcessRequest(HttpContext context) { DataSet dataSet = new DataSet(); SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["ISALog1ConnectionString"].ToString()); SqlCommand cmd = new SqlCommand("exec ProxyReport", conn); cmd.CommandTimeout = 200; SqlDataAdapter ad = new SqlDataAdapter(cmd); ad.Fill(dataSet); GridView1.DataSource = dataSet.Tables[0]; GridView1.DataBind(); GridView2.DataSource = dataSet.Tables[1]; GridView2.DataBind(); GridView3.DataSource = dataSet.Tables[2]; GridView3.DataBind(); dataSet.Tables[0].TableName = "1"; dataSet.Tables[1].TableName = "2"; dataSet.Tables[2].TableName = "3"; int count = 3; MemoryStream ms = GetExcel.DataTableToExcelXlsx(dataSet, count); ms.WriteTo(context.Response.OutputStream); context.Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"; context.Response.AddHeader("Content-Disposition", "attachment;filename=EPPlusData.xlsx"); context.Response.StatusCode = 200; context.Response.End(); } public bool IsReusable { get { return false; } } public static MemoryStream DataTableToExcelXlsx(DataSet ds, int count) { MemoryStream Result = new MemoryStream(); ExcelPackage pack = new ExcelPackage(); for (int i = 1; i <= count; i++) { DataTable table = ds.Tables[i.ToString()]; ExcelWorksheet ws = pack.Workbook.Worksheets.Add("MySheet" + i.ToString()); int col = 1; int row = 1; foreach (DataColumn cl in table.Columns) { ws.Cells[row, col].Value = cl.ColumnName; col++; } col = 1; foreach (DataRow rw in table.Rows) { foreach (DataColumn cl in table.Columns) { if (rw[cl.ColumnName] != DBNull.Value) ws.Cells[row + 1, col].Value = rw[cl.ColumnName].ToString(); col++; } row++; col = 1; } } pack.SaveAs(Result); return Result; } }}
