C# wcf passing array parameter, encountering System.ServiceModel.FaultException

Question

I notice that if i send an array on webservice with array parameter, I encounter the unhandled errorexception but, when i send plain string, i could send the data on webservice with string parameter. I'd searched and follow the threads to pass the array but, it did not work. did i miss something?

client side:
LocalService.Service1Client a = new LocalService.Service1Client();

        LocalService.PersonalDetail[] Entity = new LocalService.PersonalDetail[1];
        LocalService.PersonalDetail Entity2 = null;

        Entity2 = new LocalService.PersonalDetail();
        Entity2.Firstname = "TEST";
        Entity2.Lastname = "TEST";
        Entity2.Middlename = "TEST";
        Entity2.CreatedDate = DateTime.Today;
        Entity[0] = Entity2;

        a.Open();
        Console.Write(a.GetLookOutList(Entity));
        a.Close();

public string GetLookOutList(PersonalDetail[] obj)
{
    IResponse Lol = new LookOutList(obj);
    return Lol.Response();
}

One of those inner lines is throwing an exception.

To verify, try this:

public string GetLookOutList(PersonalDetail[] obj)
{
    return "TEST";
}

This will work.

Now you need to debug your code. Set a breakpoint to the first line IResponse Lol = new LookOutList(obj); and start the debugging process. You can find help on the specific exception you got here.
