将GridView中的数据导入到EXCEL中！解决方案

 1    protected void Button1_Click(object sender, EventArgs e)
 2    {
 3        Response.Clear();
 4        this.GridView1.Columns[0].Visible = false;  //第一列是复选框，将其屏蔽
 5        this.GridView1.FooterRow.Visible = false;　//屏蔽脚注
 6        for (int i = 0; i < this.GridView1.Rows.Count; i++)
 7        {
 8            if (!((CheckBox)this.GridView1.Rows[i].FindControl("CheckBox2")).Checked)
 9            {
                this.GridView1.Rows[i].Visible = false;　　//如果该行未被选中，屏蔽！
            }
        }

        this.GridView1.BottomPagerRow.Visible = false;　//把页数，也屏蔽掉　就是 1 2 3 4页　　　　


        Response.Buffer = true;
        Response.Charset = "GB2312";
        Response.AppendHeader("Content-Disposition", "attachment;filename=Exclefile.xls");
        // 如果设置为 GetEncoding("GB2312");导出的文件将会出现乱码！！！
        Response.ContentEncoding = System.Text.Encoding.UTF7;
        Response.ContentType = "application/ms-excel";//设置输出文件类型为excel文件。 
        System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
        System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
        this.GridView1.RenderControl(oHtmlTextWriter);
        Response.Output.Write(oStringWriter.ToString());
        Response.Flush();
        Response.End();
    }
//下面这个函数一定要有的,否则会报错.
    public override void VerifyRenderingInServerForm(Control control)
    { }
