Generic exception handling

I my WCF project, by every call I make to the host, I have a try/catch block, which look like the next:

Code:

---

        try {
            //call WCF methods
        }
        catch (FaultException<MyCustomException> ex) {
            //do stuff
        }
        catch (FaultException ex) {
            //do stuff
        }
        catch (CommunicationException) {
            //do stuff
        }
        catch (TimeoutException) {
            //do stuff
        }
        catch (Exception ex) {
            // do stuff
        }

---

With different exceptions I want to do different things. To avoid copy/paste this to every call I make to the WCF host, I want to make this generic.

I create the next solution:

Code:

---

public static class WCFclient{
    public static void InvokeCall(Action action){
        try {
            action();
        }
        catch (FaultException<MyCustomException> ex) {
            //do stuff
        }
        catch (FaultException ex) {
            //do stuff
        }
        catch (CommunicationException) {
            //do stuff
        }
        catch (TimeoutException) {
            //do stuff
        }
        catch (Exception ex) {
            // do stuff
        }
    }
}

public class Form1{
    private void button1_Click(object sender, EventArgs e) {
        TestProject.MyFirstServiceClient proxy = new TestProject.MyFirstServiceClient();
        WCFclient.InvokeCall(delegate{
            _service.Open();
            _service.CallFirstMethod();
        });
        //close service     
    }

    private void button2_Click(object sender, EventArgs e) {
        TestProject.MyFirstServiceClient proxy = new TestProject.MyFirstServiceClient();
        WCFclient.InvokeCall(delegate{
            _service.Open();
            _service.CallSecondMethod();
        });
        //close service     
    }
}

---

So far, it works. But it goes wrong when I call the InvokeCall with another service (when an exception happens). The reason for this is because the type of 'MyCustomException' is TestProject.MyFirstServiceClient.MyCustomException. When I call a method of MySecondServiceClient, and the custom exception is thrown, the type of this exception is TestProject.MySecondServiceClient.MyCustomException and it goes directly to the standard FaultException.

So I need make it more generic. What I am trying to do is something like

Code:

---

public static void InvokeCall<T>(Action action){
  ...
}

---

But now I need to cast the exception to the correct type.

How do I do this? Is the only way to do this using Reflection?
