Yes, there is a bug, but I'm a little confused by your test.  NMock will 
only verify the value of a parameter, not the actual reference.  In your 
test, you assign the variable 'refStringArr' to null, then pass it to your 
mock.  This will fail (assuming the bug has been fixed) because NMock is 
expecting the original value assigned to strArr, which was {"a", "b"}. 
Even if NMock could have compared the reference refStringArr with strArr, 
however, it still would have failed, because they are different 
references.  So I'm not sure what you expect the behavior to be.
 
Anyway, I have fixed the bug, and it should make its way onto SourceForge 
in the next day or so.

Subject: [Nmock-general] Problem with 'ref string[]' parameter

Hello

I've got a problem with creating a DynmicMock for a Interface with
a Function that takes a 'ref string[] foo' parameter. (see example below).

The function is defined as 
bool ByRefFunction(ref string[] strArray);

the problem is that the ExpectAndReturn function of nMock didn't find the 
method signature (so it tells in the exception).

Since some messages on the list archives showed a equal problem, i've got
the latest nmock.dll from 
http://ccnetlive.thoughtworks.com/NMock-builds/131/
(was mentoind in a list message).

Please find a example below!

The ByRefFunction is suposed to cange to given array to { "a", "b" }, so 
the
nunit tests should conform.

Did i miss something or is it a bug?

kind regards
Dominik

    }

            Mock fooMock = new DynamicMock(typeof(IFoo));

            fooMock.ExpectAndReturn("Function", true, (object)strArr);

            IFoo foo = (IFoo)fooMock.MockInstance;
            bool bar = foo.Function(strArr);

            Assert.IsTrue(bar);

            fooMock.Verify();
        }

            Assert.AreEqual("a", refStringArr[0]);
            Assert.AreEqual("b", refStringArr[1]);
            Assert.IsTrue(bar);
