For ASP.Net web form applications, you can use [for file download]<\/p>\n

Synchronously<\/h2>\n
\r\nusing<\/span> System.Net;\r\n\r\nWebClient<\/span> webClient = new<\/span> WebClient<\/span>();\r\nwebClient.DownloadFile<\/strong>(\"http:\/\/mysite.com\/myfile.txt\"<\/span>, @\"c:myfile.txt\"<\/span>);\r\n\r\nor\r\n\r\n<\/pre>\n
Asynchronously<\/h2>\n
private void<\/span> btnDownload_Click(object<\/span> sender, EventArgs<\/span> e)\r\n{\r\n  WebClient<\/span> webClient = new<\/span> WebClient<\/span>();\r\n  webClient.DownloadFileCompleted += new<\/span> AsyncCompletedEventHandler<\/span>(Completed);\r\n  webClient.DownloadProgressChanged += new<\/span> DownloadProgressChangedEventHandler<\/span>(ProgressChanged);\r\n  webClient.DownloadFileAsync<\/strong>(new<\/span> Uri<\/span>(\"http:\/\/mysite.com\/myfile.txt\"<\/span>), @\"c:myfile.txt\"<\/span>);\r\n}\r\n\r\nprivate void<\/span> ProgressChanged(object<\/span> sender, DownloadProgressChangedEventArgs<\/span> e)\r\n{\r\n  progressBar.Value = e.ProgressPercentage;\r\n}\r\n\r\nprivate void<\/span> Completed(object<\/span> sender, AsyncCompletedEventArgs<\/span> e)\r\n{\r\n  MessageBox<\/span>.Show(\"Download completed!\"<\/span>);\r\n}\r\n\r\n--\r\nAnother Simple Approach : When you are using Ajax or Web-Service in Ajax style (.asmx), this will be handy though will expose the file path. For publicly open applications use it with care and take required security pre-cautions.\r\n\r\nuse the regular anchor tag with download attribute.<\/pre>\n
