将页面输出到文件用法

将页面输出到文件用法 一、定义文档类型、字符编码 Response.Clear(); Response.Buffer= true; Response.Charset="utf-8"; //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=FileFlow.xls"); Response.ContentEncoding=System.Text.Encoding.GetEncoding("utf-8"); //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; 二、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); 三、将目标数据绑定到输入流输出 this.RenderControl(oHtmlTextWriter); //this 表示输出本页,你也可以绑定datagrid,或其他支持obj.RenderControl()属性的控件 Response.Write(oStringWriter.ToString()); Response.End(); 总结:本例程在Microsoft Visual Studio .NET 2005平台下测试通过,适用于C#和VB,根据需要存放的内容可吧this改为服务器控件。 解决中文乱码方案: protected void Button4_Click(object sender, EventArgs e) { Response.Clear(); Response.Buffer = true; Response.Charset = "GB2312"; Response.AddHeader("Content-Disposition", "attachment; filename=" + System.Web.HttpUtility.UrlEncode("中文", System.Text.Encoding.UTF8) + ".xls");//这样的话,可以设置文件名为中文,且文件名不会乱码。其实就是将汉字转换成UTF8 // 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excel文件。 System.IO.StringWriter oStringWriter = new System.IO.StringWriter(); System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter); Panel1.RenderControl(oHtmlTextWriter);//Add the Panel into the output Stream. //this.GridView1.RenderControl(oHtmlTextWriter);//将gridview输出,你也可以类似的写TextBox1.RenderControl... Response.Output.Write(oStringWriter.ToString());//Output the stream. Response.Flush(); Response.End(); } //End of the Print data code. //重载VerifyRenderingInServerForm方法,否则运行的时候会出现如下错误提示:“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) { //override VerifyRenderingInServerForm. } ------------------------------------------------------------------------------------------- Response.Clear(); Response.Buffer = true; Response.Charset = "GB2312"; Response.AddHeader("Content-Disposition", "attachment; filename=" + System.Web.HttpUtility.UrlEncode("中文", System.Text.Encoding.UTF8) + ".xls");//这样的话,可以设置文件名为中文,且文件名不会乱码。其实就是将汉字转换成UTF8 // 如果设置为 GetEncoding("GB2312");导出的文件将会出现乱码!

Response.Output.Write(oStringWriter.ToString());//Output the stream.
