Is it possible to skip visibility checks when generating dynamic IL with MethodBuilder's?

Question

When generating IL using DynamicMethod it's possible to call methods and access fields that would be otherwise un-accessible if you provide 'true' for the restrictedSkipVisibility parameter in the DynamicMethod constructor

I would prefer to emit dynamic IL into a dynamic assembly instead so I can save the generated IL into an assembly at build time. If I use this method I have to use a MethodBuilder instead of a DynamicMethod. However I need to be able to skip visibility checks so I don't get MethodAccessException's when I run my dynamic code. Is there a way to do this and if so how?

Answer 1

When using MethodBuilder into a dynamic assemblies, you are bound to the same rules as the compiler generated assemblies. So, inter-assembly visibility is governed by:

• The ReflectionPermission attribute.
• The InternalsVisibleTo attribute.

Please read the documentation and the samples, to see if it could fit your needs.

Answer 2

if you need to materialize your generated code by interface instead of delegate, il will be usefull to skipVisibilityCheck for a Methodbuilder. I did not find a way to do it directly, but you can simple call a DynamicMethod in your MethodBuilder by using EmitCalli(OpCodes.Calli...).
