从DataGrid输出数据到Excel

方法很简单,只是将DataGrid的内容输出到HtmlTextWriter流,再将流作为附件让用户下载或者用Excel打开.

此方法虽然简单,但能实现功能.

private void button_OutExcel_Click(object sender, System.EventArgs e)
  {
   Response.Clear();

    Response.Buffer= true;

    Response.Charset="utf-8";  

   this.EnableViewState = false;  

   //定义输入流
   System.IO.StringWriter writer = new System.IO.StringWriter();
   System.Web.UI.HtmlTextWriter txtwriter = new HtmlTextWriter(writer);
            //将DataGrid中的内容输出到txtwriter流中
   this.DataGrid1.RenderControl(txtwriter);

   //作为附件输出,filename=FileFlow.xls 指定输出文件的名称,注意其扩展名和指定文件类型相符,可以为:.doc    .xls    .txt   .htm  

            Response.ContentType = "application/ms-excel"; //ContentType指定文件类型 可以为application/ms-excel    application/ms-word    application/ms-txt    application/ms-html    或其他浏览器可直接支持文档 

    Response.AppendHeader("Content-Disposition","attachment;filename=FileFlow.xls"); //下载

    //Response.ContentEncoding=System.Text.Encoding.GetEncoding("utf-8");  
   Response.Write(writer);
   Response.End();

  }
