HttpClient, catch can't connect

Question

I have the following code:

        ProgressMessageHandler progress = new ProgressMessageHandler();
        progress.HttpSendProgress += new EventHandler<HttpProgressEventArgs>(HttpSendProgress);
        HttpRequestMessage message = new HttpRequestMessage();
        message.Method = HttpMethod.Post;
        message.Content = content;
        message.RequestUri = new Uri("http://myaddress");
        var client = HttpClientFactory.Create(progress);
        sending = client.SendAsync(message);


    private void HttpSendProgress(object sender, HttpProgressEventArgs e)
    {
         //....
    }

I want to catch a situation, when "myaddress" is not available. Method HttpSendProgress is called when progress is active, so, I can't check in this method. Any way to check if "myaddress" is available. I have an idea to start one more thread to check when HttpSendProgress is called last time. But maybe there is a standard method?

I dont think you can check if the address is a working address in the progress event. You need to check the status after the response has come back.

    if (response.IsSuccessStatusCode)
    {
        Console.WriteLine(response.StatusCode.ToString());
    }

How to determine a 404 response status when using the HttpClient.GetAsync()

response is not come back. It waits unlimited time :( – Oleg Sh Jan 18 '15 at 01:08
Have you set `timeout`? `client.Timeout = Timespan.FromSeconds(30)`. This should comeback with a response in 30 seconds – Kallol Jan 18 '15 at 01:47
