for (int i = 0; i < 10; i++)

DataRow row = table.NewRow();

row["name"] = "Name_" + i.ToString();

row["age"] = 20 + i;

table.Rows.Add(row);

}

DataGrid dg = new DataGrid();

dg.DataSource = table;

dg.DataBind();

//定义文档类型、字符编码

Response.Clear();

Response.Buffer = true;

Response.Charset = "GB2312";

//下面这行很重要， attachment 参数表示作为附件下载，您可以改成 online在线打开

//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.AppendHeader("Content-Disposition", "attachment;filename=" + filename);

Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");

//Response.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.ContentType = "application/ms-excel";

this.EnableViewState = false;

//　定义一个输入流

System.IO.StringWriter oStringWriter = new System.IO.StringWriter();

System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);

通过Datagrid导出Excel

通过HTMLTable导出Excel

通过literal导出Excel

将本页内容导出为Excel

Response.Write(oStringWriter.ToString());

Response.End();
