Code Sample: Programmatically Download File Using C#

September 17th, 2008 | 5 Comments | Posted in Programming

While browsing forums today I came across a question which asked for a solution to download a file from a web server programmatically. The solution is very simple and below is the code which achieves the goal. Here I am downloading a file asynchronously on Button Click.







   1: private void buttonDownloadFile_Click(object sender, EventArgs e)


   2: {


   3:     string url


   4:         = @"http://www.onedotnetway.com/wp-content/uploads/2008/08/image35.png";


   5:


   6:     // Create an instance of WebClient


   7:     WebClient client = new WebClient();


   8:


   9:     // Hookup DownloadFileCompleted Event


  10:     client.DownloadFileCompleted +=


  11:         new AsyncCompletedEventHandler(client_DownloadFileCompleted);


  12:


  13:     // Start the download and copy the file to c:\temp


  14:     client.DownloadFileAsync(new Uri(url), @"c:\temp\image35.png");


  15: }


  16:


  17: void client_DownloadFileCompleted(object sender, AsyncCompletedEventArgs e)


  18: {


  19:     MessageBox.Show("File downloaded");


  20: }










You can also download the file synchronously using WebClient.DownloadFile() method.

    Hello! Thank you for the post.
    

    I am anxious to know if this will work on computer behind PROXY?

    Thanks. If it does not work then you can set WebClient.UseDefaultCredentials. This should do the trick. And if you have to specify credentials for your proxy explicitly then you can set WebClient.Credentials property.
    

    Hope this helps.
