Send .NET class instance to MATLAB function

Hi all,

Here is what i want to do: I'm in C# and I have a compiled MATLAB dll for .NET via the Compiler SDK.

Here the C# code:

private DelegateTest.Class1 _delegate = new DelegateTest.Class1();

// creates a class instance and sends it to my MATLAB function
private void btnRun_Click(object sender, RoutedEventArgs e)
      {
          try
          {
              MyThing _thing = new MyThing();
              MWObjectArray instanceWrapper = new MWObjectArray(_thing);
              MWArray[] result = new MWArray[2];
              result = (MWArray[])_delegate.DelegateTest(2, instanceWrapper);
              foreach (MWArray item in result)
                  Console.WriteLine(item);
          }
          catch (Exception ex)
          {
              MessageBox.Show(ex.Message);
          }
      }

// A Test Class which creates a Value
public class MyThing
      {
          public int ValueCreator()
          {
              return 42;
          }
      }

Here is my MATLAB function:

function [output1, output2] = DelegateTest(instance)
    try        
        if isa(instance, 'ExecuteMatlabScriptInCSharo.MyThing')
             output1 = 'Correct Type';
        else
            output1 = 'Wrong Type';
        end

          result = instance.ValueAusdenker();
      catch ex
          output2 = getReport(ex);
          return
      end

      output2 = result;   
  end

Here is the output of the result after i execute it:

1. [0] {Correct Type} MathWorks.MATLAB.NET.Arrays.MWArray {MathWorks.MATLAB.NET.Arrays.MWCharArray}
2. [1] {Error using DelegateTest (line 9)Message: Object does not match target type. Source: mscorlib HelpLink: } MathWorks.MATLAB.NET.Arrays.MWArray {MathWorks.MATLAB.NET.Arrays.MWCharArray}

Anyone has an idea how this is going to work? Or is it simply not possible?

Thanks!
