RhinoMocks: How to run custom delegate with parameter supplied to method?

I have a class that has a create method, passing into it a POCO entity. What I want to happen is that I attach a delegate to the method call like so:

stubObject.Stub(Function(i) i.Create(Arg(of MyObject).Is().Anything))) _
   .Return(True)

What I want to do is to take the instance of the parameter passed to Create and run a custom action. I thought Do() with a delegate would do the trick, but I can't get RhinoMocks 3.6 (.NET 4) to allow me to enter a parameters.

Where am I doing wrong? I can't do this:

stubObject.Stub(Function(i) i.Create(Arg(of MyObject).Is().Anything))) _
   .Return(True) _
   .Do(Sub(i) ...)

Thanks.

Solution

  • I think what you want is the "WhenCalled" option. See this SO question for an example of how it can be used to grab the arguments passed to the mocked call.
