首先，您必须将以下内容添加到page指令以避免运行时错误

 EnableEventValidation ="false"

将gridview添加到aspx页面会话“dsource”从包含连接字符串和select命令的高级搜索页面传递数据源那么这里是代码

using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Data.SqlClient;
using System.Threading;
using System.IO;
using System.Reflection;

public partial class csresults : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{

    gridview1.DataSource = Session["dsource"];
    gridview1.DataBind();




}


  public override void VerifyRenderingInServerForm(Control control)
{

}



protected void Button2_Click(object sender, EventArgs e)
{
    HtmlForm form = new HtmlForm();
    string attachment = "attachment; filename=Patients.xls";
    Response.ClearContent();
    Response.AddHeader("content-disposition", attachment);
    Response.ContentType = "application/ms-excel";
    StringWriter stw = new StringWriter();
    HtmlTextWriter htextw = new HtmlTextWriter(stw);
    form.Controls.Add(gridview1);
    this.Controls.Add(form);
    form.RenderControl(htextw);
    Response.Write(stw.ToString());
    Response.End();
}

}

将“导出到Excel”按钮添加到网页，以将gridview导出到web应用程序中的Excel
