How to find if a parameter is struct?

[deedee]

Hi,

I have been trying to determine if a parameter in a methodDefinition
is a struct or not. But it appears to have similar set of properties
as any passed by reference parameter would have.
Any ideas?

Thanks!

The reason I am baffled because the IsValueType returns false for a struct, when I check for "parameterReference.ParameterType.IsValueType".
Am I doing something wrong here?

This looks weird. Can you send me an assembly which reproduces this ?

As a workaround, you can call .Resolve on the TypeReference to get a TypeDefinition that will have the proper ValueTypeness.

Hi,
Thanks for the workaround, that works just fine! And I noticed that those methods had the structs passed by ref...so maybe that was the problem!
Thanks again!

Then no, it's not a problem.

The ParameterType will be a ByReferenceType, whose ElementType will be the original Value Type, with .IsValueType returning true.
