程序生成文件下载

 

 protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
    ...{
        string strMaxID = this.GridView1.DataKeys[e.NewEditIndex].Values[0].ToString();
        string strMinID = this.GridView1.DataKeys[e.NewEditIndex].Values[1].ToString();
        string strCount = this.GridView1.Rows[e.NewEditIndex].Cells[2].Text;
  
        Response.Clear();
        Response.Buffer = true;
        Response.Charset = "GB2312";
        Response.AppendHeader("Content-Disposition", "attachment;filename=ContractCode.xls");
        // 如果设置为 GetEncoding("GB2312");导出的文件将会出现乱码！！！
        Response.ContentEncoding = System.Text.Encoding.UTF8;
        Response.ContentType = "application/ms-Excel";//设置输出文件类型为txt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);


        oStringWriter.Write("编号："+strMinID + "至" + strMaxID+",共"+strCount+"份。");

        Response.Output.Write(oStringWriter.ToString());
        Response.Flush();
        Response.End();        
    }
