This should be cast to an HttpWebResponse if the Url you are passing uses HTTP or HTPS as the protocol.

HttpWebResponse responseObject = (HttpWebResponse)WebRequestObject.GetResponse();

You will then find a StatusCode property which contains the detail you want.

Read the documentation!! here[^]

StatusCode is an enumeration, 'OK' = 200. Just write yourself a method to return a string of the numbers based on the value of StatusCode.

In C# we do this by putting the code below where the On Error Goto would be inside a try block. The Err label is replaced by catch block(s). In addition we have an optional finally block that is run after either have completed:

try
{
    // code that may throw an exception
}
catch(Exception ex)
{
   // an exception is now in ex so you can examine this to get details,
   // show detailed MessageBox etc...
}
finally
{
   // this will run regardless of whether an exception was thrown or not.
   // useful to close/dispose of objects etc...
}

More details here[^].

Which error do you want the number for? I've had most of them in my time, so I might be able to let you have it.

Have you tried looking at the GetLastError API method? I think that there's a managed wrapper around that which may help (Marshal.GetLastWin32Error I think)

Even a quick google would have shown that to be untrue. If you google it, the first thing you see is:
GetLastError Function (Windows)
Retrieves the calling thread's last-error code value.
