How to Pass Complex structure From Matlab WorkSpace to .Net Application ?

I have a structure in Matlab workSpace Ex Person. Now I wish to Pass this structure to my .Net Application So that I can launch GUI so that user can can Modify that easity and then Pass the Modified structure back to workspace.

%Declaring Struct. person.LastName = 'Clinton' person.Name = 'Donald'

%Loading .Net DLL asm = NET.addAssembly('ModifyStructTool.dll'); self.f=ViewModifyCalTool.MainForm(''); self.f.SetObj(p)

Error: No method 'SetObj' with matching signature found for class 'ViewModifyCalTool.MainForm'.

.Net Code public struct Person { public string Name; public string LastName; }

    public void SetObj(Person varargin)
        {
            //Launch GUi and Edit.
        }

When I call the function 'SetObj' it gives below error Error: No method 'SetObj' with matching signature found for class 'ViewModifyCalTool.MainForm'.

I am not sure how to Cast/Marshal struct from Matlab to C#
