How to fix a Object Reference Error?

[mbewers1]

Hi

The method below fails on the line marked in bold and I receive an object reference error. I know that this is a common error but, I've tried changing several assignments to ensure they match up with the required types and it the method still fails.

I also tried:

agentResponse(0).InputData = testMetaDataArray

without the () after .InputData, but that still fails as well.

Just for extra information:

MetaDataRespons eSet is an array type and is what is required by the AgentResponseTo DTO() method.

MetaDataGroup is also an array type which has various properties, the only two I need to assign to are .Name and .Size

Public Sub TestAgentResponseToDTOResponseFieldSize2()

        Dim agentResponse(0) As MetaDataResponseSet

        ''Create a MetaDataGroup object that can store 2 items
        Dim testMetaDataArray(1) As MetaDataGroup

        Dim mdaObject1 As MetaDataGroup = New MetaDataGroup()
        mdaObject1.Name = "my name"
        mdaObject1.Size = 3

        Dim mdaObject2 As MetaDataGroup = New MetaDataGroup()
        mdaObject2.Name = "is Mathieu"
        mdaObject2.Size = 6

        testMetaDataArray(0) = mdaObject1
        testMetaDataArray(1) = mdaObject2

        'testMetaDataArray(0).Name = "my name"
        'testMetaDataArray(0).Size = 3

        
        [B]agentResponse(0).InputData() = testMetaDataArray[/B] '' fails here

        '' Create a result object
        Dim result As Boolean = True

        Dim assemblerResponse = ExperianBankValMetaDataCallAssembler.AgentResponseToDTO(agentResponse)

        Assert.AreEqual(agentResponse(0).InputData(0).Size, assemblerResponse.InputFields(0).Length)
        Assert.AreEqual(agentResponse(0).InputData(0).Name, assemblerResponse.InputFields(0).Name)

        Assert.AreEqual(agentResponse(0).InputData(1).Size, assemblerResponse.InputFields(1).Length)
        Assert.AreEqual(agentResponse(0).InputData(1).Name, assemblerResponse.InputFields(1).Name)

        Assert.AreEqual(result, assemblerResponse.Result.Success)

    End Sub

I hope that you can clearly understand this method without me having to show the related class code.

Can anyone see where I've gone wrong?

Thank, Matt
