asp.net做下载时下载下来的总是aspx页面
现在项目中用到这个功能，弄了一天也没弄好，我的代码如下：
string Txt = friendBll.outFriend(userid, groupid);//获取文件内容
fileName = groupBll.getFile(groupid).ToString();//文件名称
fileName += DateTime.Now.ToShortDateString();

string strFileName = HttpUtility.UrlEncode(fileName) + ".txt"; //文件名
Response.Clear();
Response.BufferOutput = false;
Response.ContentEncoding = System.Text.Encoding.GetEncoding("UTF-8");
Response.ContentType = "text/html";
Response.AddHeader("Content-Disposition", string.Format("attachment;FileName= {0}",strFileName));
byte[] bytes = Encoding.GetEncoding("UTF-8").GetBytes(Txt);
Response.BinaryWrite(bytes); //文件流
Response.Flush();
Response.Close();
Response.End();
