How to invoke (non virtually) the original implementation of a virtual method?

Question

I have the following situation:

In a 3rd party library (can not be modified):

class A { public virtual void M() {} }

class B : A { public override v         


        

Answer 1

you can generate dynamic method to make proxy that use Call (not CallVirt) instruction

        var x = new C();
        var m = typeof (A).GetMethod("M");
        var dm = new DynamicMethod("proxy",  typeof (void), new [] {typeof(C)}, typeof (C));
        var il = dm.GetILGenerator();
        il.Emit(OpCodes.Ldarg_0);
        il.Emit(OpCodes.Call, m);
        il.Emit(OpCodes.Ret);
        var action = (Action)dm.CreateDelegate(typeof (Action));
        action(x);
