<p>I am using a mock object in RhinoMocks to represent a class that makes calls to MessageQueue.GetPublicQueues. I want to simulate the exception thrown when message queueing is operating in workgroup mode, which is a MessageQueueException, to ensure that I am catching the exception correctly</p>

<p>The MessageQueueException has no public constructor, only the standard protected constructor for an exception. Is there an appropriate way to throw this exception from the mock object / Expect.Call statement?</p>

Reflection can break the accessibility rulez.  You
will
void the warranty, a .NET update can easily break your code.  Try this:
```
```
using System.Reflection;
using System.Messaging;
...
        Type t = typeof(MessageQueueException);
        ConstructorInfo ci = t.GetConstructor(BindingFlags.NonPublic | BindingFlags.Instance, 
          null, new Type[] { typeof(int) }, null);
        MessageQueueException ex = (MessageQueueException)ci.Invoke(new object[] { 911 });
        throw ex;
```
```
