关于文件下载的问题！下面这段代码为什么在执行时文件总被浏览器直接打开，而不提示下载呢？高分求救！急，谢谢！代码如下：

[dicklee1214]

string createPath = Server.MapPath("../CardAdmin/file/CardCreate" + this.txtbxBatchNO.Text +".txt");
FileInfo DownloadFile = new FileInfo(createPath);
Response.Clear();
Response.ClearHeaders();
Response.Buffer = false;
Response.ContentType = "application/octet-stream ";
Response.AppendHeader("Content-Disposition ", "attachment;filename= " + HttpUtility.UrlEncode(DownloadFile.FullName, System.Text.Encoding.UTF32));
Response.AppendHeader("Content-Length ", DownloadFile.Length.ToString());
Response.WriteFile(DownloadFile.FullName);
Response.Flush();
Response.End();

运行环境是xp+IE7.0点快了！分不够高，可另开新贴给回复者加分！

string createPath = Server.MapPath( "../CardAdmin/file/CardCreate " + this.txtbxBatchNO.Text + ".txt ");
FileInfo DownloadFile = new FileInfo(createPath);
Response.Clear();
Response.ClearHeaders();
Response.Buffer = false;
Response.ContentType = "application/octet-stream ";
Response.AddHeader( "Content-Disposition ", "attachment;filename= " + HttpUtility.UrlEncode(DownloadFile.FullName, System.Text.Encoding.UTF32));
Response.AddHeader( "Content-Length ", DownloadFile.Length.ToString());
Response.TransmitFile(DownloadFile.FullName);
Response.Flush();
Response.End();

还有你是什么文件类型

[dicklee1214]

Server.MapPath( "../CardAdmin/file/CardCreate " + this.txtbxBatchNO.Text [b]+ ".txt ");这个当然是txt文件了，除了空格宽了，其他你好像什么也没有改吧？怎么会能行呢

[wuxing2006]

难道 是RPWT呵，空格是CSDN的问题，仔细看看

[dicklee1214]

rpwt是什么？
