Hi Everyone,

I am trying to handle two different WebException's properly.

Basically they are handled after calling WebClient.DownloadFile(string address, string fileName)

AFAIK, so far there are two I have to handle, both WebException's:

• The remote name could not be resolved (i.e. No network connectivity to access server to download file)
• (404) File not nound (i.e. the file doesn't exist on the server)

There may be more but this is what I've found most important so far.

So how should I handle this properly, as they are both WebException's but I want to handle each case above differently.

This is what I have so far:

try
{
    using (var client = new WebClient())
    {
        client.DownloadFile("...");
    }
}
catch(InvalidOperationException ioEx)
{
    if (ioEx is WebException)
    {
        if (ioEx.Message.Contains("404")
        {
            //handle 404
        }
        if (ioEx.Message.Contains("remote name could not")
        {
            //handle file doesn't exist
        }
    }
}

As you can see I am checking the message to see what type of WebException it is. I would assume there is a better or a more precise way to do this?

Thanks
