How to define if default browser opens the needed page?

Question

I have my program written in C#. It has label link. I need to define programmatically, when I click this link (programmatically too), if default browser opens the needed page. C#

Answer 1

Process.Start("http://example.com"); // <-- put your url there.

Also see this short article on how to use that to greatest effect:

In summary:

void OpenBrowser(string url)
{
    try
    {
        Mouse.OverrideCursor = Cursors.AppStarting;
        Process.Start(url);
    }
    catch (Exception)
    { //swallow: exception is sometimes thrown even though
    } // the call completed without error
    finally
    {
        Mouse.OverrideCursor = null;
    }
}
