问题
I see in the CSharpInteractive.rsp you can add a reference to a DLL in the GAC using /r:
How do you add references to your own DLLs?
I tried System.Reflection.Assembly.LoadFrom, it didn't fail but didn't work.
I am trying to add a reference to my DLL that has extension methods.
If I try to add the code for the extension method directly in the interactive window I get this error:
error CS1109: Extension methods must be defined in a top level static class; XYZ is a nested class
回答1:
You should be able to specify a full path for the assembly, in the same way as the gac assembly.
Normally you don't need to change the rsp though. You can add references in a regular submission using:
#r "path"
