How to check the Internet connection with .NET, C#, and WPF

Question

I am using .NET, C# and WPF, and I need to check whether the connection is opened to a certain URL, and I can\'t get any code to work that I have found on the Internet.

Answer 1

Use this:

private bool CheckConnection()
{
    WebClient client = new WebClient();
    try
    {
        using (client.OpenRead("http://www.google.com"))
        {
        }
        return true;
    }
    catch (WebException)
    {
        return false;
    }
}
