[Nmock-general] BUG: problem with indexers and multiple args

[Vaughn, C. <Va...@va...>]

I discovered this problem with VB code because you can easily create
properties that take arguments, but I recreated it in C# with an indexer.
Here's a test to reveal the bug:

		public interface IDiffIndexers
		{
			object this[ int index ] { get; }
			object this[ int index, int index2 ] { get; }
		}

		public void TestGetItem()
		{
			IMock foo = new DynamicMock( typeof( IDiffIndexers )
);
			foo.ExpectAndReturn( "Item", "bob", 0 );
		
			Assertion.AssertEquals( "retval", "bob",
((IDiffIndexers)foo.MockInstance)[0] );
		}

... and my hack of a fix....

		void checkMethodIsValidIfNoConstraints(MethodSignature
signature)
		{
			foreach(Type argType in signature.argumentTypes) 
			{
	
if(typeof(IConstraint).IsAssignableFrom(argType)) return;
			}

			Type[] allTypes = new InterfaceLister().List(type);
			foreach (Type t in allTypes) 
			{
				string [] prefixes = new string[] { "",
"get_", "set_" };

				foreach ( string prefix in prefixes )
				{
					MethodInfo method =
t.GetMethod(prefix + signature.methodName,
ClassGenerator.ALL_INSTANCE_METHODS, null,
						signature.argumentTypes,
null);

					if(method != null)
					{
						if(!method.IsVirtual) 
						{
							throw new
ArgumentException(String.Format("method <{0}> is not virtual", signature ));
						}
						return;
					}
				}
			}
			throw new
MissingMethodException(String.Format("method <{0}> not defined", signature
));
		}
