You may declare the Variant type of v1 explicitly:

v1.vt = VarTypes.VT_BOOL;

But i suppose that will lead to the next Exception: "COMException: A VT_VARIANT must be combined with VT_BYREF (base vartype 12)". Combining the Type with a VT_ARRAY and/or a VT_BYREF leads to "Unable to serialize variant" Exception again. I think the problem isn't specific to invoking the msmqMessage.Send method but to passing a variant array as an argument. It seems that there existst nor any documentation how to pass a variant array as an argument nor a working example for that: The example at http://discuss.develop.com/archives/wa.exe?A2=ind0307e&L=jawin&D=0&T=0&P=1722 doesn't work for me. And the description at http://jawinproject.sourceforge.net/jawinuserguide_dispatch.html#dispatchptr_usage_methods_arrays isn't sufficient, at least for me.
