How Can I Increase the Timeout for a .NET WebClient Download?

Handling Timeouts When Downloading with .NET WebClient

Downloading data from a slow server using the standard .NET WebClient can lead to timeout exceptions. This can be resolved by increasing the timeout period.

A common solution involves creating a derived class that overrides the GetWebRequest method. This allows you to customize the request's timeout settings.

Here's how to implement this:

<code class="language-csharp">private class ExtendedWebClient : WebClient
{
    protected override WebRequest GetWebRequest(Uri uri)
    {
        WebRequest request = base.GetWebRequest(uri);
        request.Timeout = 20 * 60 * 1000; // Set timeout to 20 minutes
        return request;
    }
}</code>

Using this ExtendedWebClient class ensures that downloads from slow servers have a longer time to complete before a timeout exception is thrown.
