For ASP.Net web form applications, you can use [for file download]
Synchronously
using System.Net;
WebClient webClient = new WebClient();
webClient.DownloadFile("http://mysite.com/myfile.txt", @"c:myfile.txt");
or
Asynchronously
private void btnDownload_Click(object sender, EventArgs e)
{
WebClient webClient = new WebClient();
webClient.DownloadFileCompleted += new AsyncCompletedEventHandler(Completed);
webClient.DownloadProgressChanged += new DownloadProgressChangedEventHandler(ProgressChanged);
webClient.DownloadFileAsync(new Uri("http://mysite.com/myfile.txt"), @"c:myfile.txt");
}
private void ProgressChanged(object sender, DownloadProgressChangedEventArgs e)
{
progressBar.Value = e.ProgressPercentage;
}
private void Completed(object sender, AsyncCompletedEventArgs e)
{
MessageBox.Show("Download completed!");
}
--
Another 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.
use the regular anchor tag with download attribute.
