CAUSE
This problem occurs because the
System.Type.InvokeMember method passes parameters only by value to COM methods. This is the default behavior.
For example, if you pass the VARIANT parameter by reference, as in the following sample code, an exception error occurs:
HRESULT _stdcall Method1(
[in, out] VARIANT* inoutVal,
[out] VARIANT* outVal,
[out, retval] VARIANT* retVal);
