其实,利用ASP.NET输出指定内容的WORD、EXCEL、TXT、HTM等类型的文档很容易的。主要分为三步来完成。
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 2003平台下测试通过,适用于C#和VB,当采用VB的时候将 this 关键字改成 me 。
