Question

I have three classes:

public class A
{
}
public class B
{
    void MethodA(ref A obj) { }

    void MethodB(A obj) { }
}
public class C : B
{
    void MethodA(ref A obj) { }
}

My first question : Are above methods are overloaded?

Second question : Difference between passing simple and refernce type objects as I know classes are reference type.

Third question : Is method in class C override method in class B ?

Answer 1

1: no; B.MethodA and C.MethodA are unrelated; the fact that they are implicitly private means it isn’t even method-hiding

2: is not a question, but: pass-by-value vs pass-by-reference (the ref keyword) is largely orthogonal to value-type vs reference-type (struct vs class); it is a commonly misunderstood subject, but I can’t really clarify without an actual question

3: no; the absence of any of virtual, override or abstract is the biggest clue
