解决方案：
页面增加一个按钮，单击事件添加如下方法：
protected void Button1_Click(object sender, EventArgs e)
{
Export("application/ms-excel", "学生成绩报表.xls");
}

private void Export(string FileType, string FileName)
{
Response.Charset = "GB2312";
Response.ContentEncoding = System.Text.Encoding.UTF7;
Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(FileName, Encoding.UTF8).ToString());
Response.ContentType = FileType;
this.EnableViewState = false;
StringWriter tw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(tw);
GridView1.RenderControl(hw);
Response.Write(tw.ToString());
Response.End();
}
//如果没有下面方法会报错类型“GridView”的控件“GridView1”必须放在具有 runat=server 的窗体标记内
public override void VerifyRenderingInServerForm(Control control)
{
}
还有由于是文件操作所以要引入名称空间IO和Text

后台代码：
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.Drawing;
using System.IO;
using System.Text;
public partial class Default7 : System.Web.UI.Page
{
SqlConnection sqlcon;
SqlCommand sqlcom;
string strCon = "Data Source=(local);Database=北风贸易;Uid=sa;Pwd=sa";
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
bind();

}
}

public void bind()
{
string sqlstr = "select top 5 * from 飞狐工作室";
sqlcon = new SqlConnection(strCon);
SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon);
DataSet myds = new DataSet();
sqlcon.Open();
myda.Fill(myds, "飞狐工作室");
GridView1.DataSource = myds;
GridView1.DataKeyNames = new string[] { "身份证号码" };
GridView1.DataBind();
sqlcon.Close();
}

protected void Button1_Click(object sender, EventArgs e)
{
Export("application/ms-excel", "学生成绩报表.xls");
}

private void Export(string FileType, string FileName)
{
Response.Charset = "GB2312";
Response.ContentEncoding = System.Text.Encoding.UTF7;
Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(FileName, Encoding.UTF8).ToString());
Response.ContentType = FileType;
this.EnableViewState = false;
StringWriter tw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(tw);
GridView1.RenderControl(hw);
Response.Write(tw.ToString());
Response.End();
}
public override void VerifyRenderingInServerForm(Control control)
{
}

}

前台：
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="3"
BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" Font-Size="12px" >
<FooterStyle BackColor="White" ForeColor="#000066" />
<Columns>
<asp:BoundField DataField="身份证号码" HeaderText="编号" ReadOnly="True" />
<asp:BoundField DataField="姓名" HeaderText="姓名" />
<asp:BoundField DataField="出生日期" HeaderText="邮政编码" />
<asp:BoundField DataField="家庭住址" HeaderText="家庭住址" />
<asp:BoundField DataField="邮政编码" HeaderText="邮政编码" />
<asp:BoundField DataField="起薪" HeaderText="起薪" />

</Columns>
<RowStyle ForeColor="#000066" />
<SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" CssClass="ms-formlabel DataGridFixedHeader"/>
<HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />
</asp:GridView>
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="导出" />
