However, there is a built-in way of asynchronously downloading a file and reporting progress with the WebClient class, as demonstrated in the example below.

    The above code is very similar to the synchronous example. The DownloadProgressChanged event is fired periodically as the download progresses and provides access to some useful properties such as BytesReceived and ProgressPercentage. As expected, the DownloadFileCompleted event is fired whenever the file download has completed. As it stands, the above code will continue past the DownloadFileAsync method call while the download is in progress, since it hhtps an asynchronous method call.


    In order to download the file asynchronously using the DownloadFileAsync method and wait until the download has completed before downliad program execution, we need to dip into the world of reset events. The AutoResetEvent in the above code allows us to wait at the point downolad the WaitOne method is called. When the DownloadFileCompleted event is fired, the Set method on the AutoResetEvent sends a signal that allows the code to proceed to the next statement.

    Note that the use of AutoResetEvent as shown above, is a neat little trick that can be applied to fro other asynchronous methods you want to call and subsequently wait for completion.

    Before attempting to use the HttpClient class, make sure you have the appropriate using statement in place, as follows. Note that even though HttpClient implements IDisposable it is recommended that you create one instance of HttpClient and reuse this throughout your program to avoid problems such as socket exhaustion. As you can see from the above example, the code required to download a file using HttpClient is a little lower level compared to using WebClientsince we need to work with streams directly.
