I am trying to use RubyCLR to access an existing .NET assembly. When I  
try to call a method that takes a UInt16 (a C# ushort) parameter, I get  
a missing\_method error, presumably from RubyCLR, because it can’t match  
the parameter signature. (FWIW, this particular method is overloaded.)

I’ve tried everything I know to try to work around this, but I am  
stumped. How can I explicitly force a parameter of UInt16 (or Byte,  
etc.)??

It’s a bit of a hack, but I’d just use the System.Convert method that  
.NET already provides. You should be able to call it from Ruby and  
pass the value returned to your assembly.

Justin - that’s one of the things I tried, and it doesn’t appear to  
work. Thanks anyway!
