Deserialization error while using int[] as a parameter

[Prabu]

Hi,
I am using Rhino mocks 3.5 for mocking our web service. I am using a
PartialMock and the mock works fine for other methods but fails for a
method which has int[] as an argument. On changing the argument to int
this works fine.

int TestMethod(int MethodIndex, IDValuePair[] MethodArguments, int[]
SecurityIds, out System.Data.DataSet ResultData, out string ErrorMsg);

Can you provide a failing test that I (we) can run?

Hi Tim,

I have a test case with the code:

 

My expectation setting for the call is like below.

Expect.On(MTInterface).Call(MTInterface.TestMethod(0, null, null, out ResultDataset, out ErrorMsg)).OutRef(ResultDataset).Return(0).IgnoreArguments().Constraints(Is.Equal(52), Is.Anything(), Is.Anything(), Is.Anything(), Is.Anything());

 

Test code makes the following call:

resultCode = MTInterface.TestMethod(52,

m_MethodParam, /*Properly populated int[] */m_securityArguments.SecurityIds, out DataSetResult, out errorMsg);

 

A call to the above method fails with the mentioned exception. Am I missing something here..?

Regards,
Prabu
