how to access exception.Response.StatusCode variable in the try with block

Question

As I'm debugging, I noticed $exception within the locals window as a result of an exception thrown implying this variable is available in the scope.

The question is how can I access this $exception variable.

How can line 78 be?

| x ->  Debug.WriteLine("exception" + $exception.Response.StatusCode)

You can catch exceptions of a specific type with this syntax:

try
  ...
with
| :? System.Net.WebException as e ->
    let response = e.Response :> System.Net.HttpWebResponse
    Console.WriteLine("exception" + response.StatusCode)

Note you need to cast WebException.Response to System.Net.HttpWebResponse so you can access its StatusCode property.

See the MSDN docs for more.

It might be worth pointing out that the case to HttpWebResponse can fail: stackoverflow.com/questions/3614034/…
