how to pass to a .NET object a struct ?

I know that a limitation is that u cannot pass to a .NET queue element a struct or array of structs.

My requirement is that I have queues whose elements are matlab structs elements How can I use the .NET Queue with MATLAB native structs? I mean is there a extra step trick I could do ?

Example: I have 5 MATLAB structs elements who I want to put in a .NET Queue and the use push , get from the .NET Queue who will get or put in queue structs elememts....

I tried with Numbers and it works,

      t = NET.createGeneric('System.Collections.Generic.Queue',{'System.Double'},10);
      t.Enqueue(1)
      t.Enqueue(2)
      t.Enqueue(3)
      x=t.GetEnumerator();
      while x.MoveNext();
          disp(x.Current)
      end
but when I try to use structs I get an error

      t = NET.createGeneric('System.Collections.Generic.Queue',{'System.Object'},10);
      c=struct('cockyStruct',1);
      No method 'Enqueue' with matching signature found for class 'System.Collections.Generic.Queue<System*Object>'.

Is there a trick or extra step I could do ?
