Hello,
Reflection seems to be pretty inconsistent with MethodInfos. In some cases
derived classes have their own MethodInfo objects for inherited (non-
overridden) methods, in some cases they get the same object as the base
class.
example:
class Base {
protected void Method1(ref int i) { }
}
class Derived: Base {
}
Main {
MethodInfo m1 = typeof(Derived).GetMethod ("Method1",
BindingFlags.NonPublic|BindingFlags.Instance);
MethodInfo m2 = typeof(MarshalByRefObject).GetMethod
("MemberwiseClone",
BindingFlags.NonPublic|BindingFlags.Instance);
}
in this case, the following expressions are true:
m1 == m1.GetBaseDefinition()
m2 != m1.GetBaseDefinition()
m1.GetBaseDefinition.ReflectedType == Base // where it is declared
m2.GetBaseDefinition.ReflectedType == MarshalByRefObject // where it was
retreived
A new MethodInfo is created for MarshalByRefObject.MemberwiseClone,
although MarshalByRefObject doesn't override or redefine it.
No new MethodInfo is created for Derived.Method1.
I also cannot see any differences in the IL code of the methods, except
that MemberwiseClone is "internal".
What's the difference? Am I missing something or is Reflection just being
dumb in this case?
Thanks,
Stefan
