让文本文件也能下载！

文本文件浏览器能够识别,点击它的时候它会直接在浏览器中打开 但有时候我们不需要这样做,我们需要下载它,于是就可以这样:         string DownloadFilePath ="c://file.txt";         Response.Clear();         Response.ContentType = "application/octet-stream";         Response.AddHeader("Content-Disposition", "attachment; filename=file.txt" );         Response.Flush();         Response.WriteFile(DownloadFilePath);        Response.End();
