C# download file from url

Introduction

This article describes code to download a file using C#...

Background

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.

Using the code

privatevoid buttonDownloadFile_Click(object sender, EventArgs e) { string url = @"http://www.thereforesystems.com/wp-content/uploads/2008/08/image35.png"; // Create an instance of WebClient WebClient client = new WebClient(); // Hookup DownloadFileCompleted Event client.DownloadFileCompleted += new AsyncCompletedEventHandler(client_DownloadFileCompleted); // Start the download and copy the file to c:\temp client.DownloadFileAsync(new Uri(url), @"c:\temp\image35.png"); } void client_DownloadFileCompleted(object sender, AsyncCompletedEventArgs e) { MessageBox.Show("File downloaded"); }

You can also download the file synchronously using method.
