Method Signature in C#

Question

What is the Method Signature in the following

int DoSomething(int a, int b);

Return type is a part of signature or not???

Answer 1

In the case when method have generic arguments understanding of signature becomes more confusing.

Generic types declaring on class level are considered as normal types.

But generic types declaring on method level are considered as index in method's generic arguments.

For example these all methods have different signatures.

class MyClass
{
    public void F(TValue v) { }       // generics: 0, arg: TValue
    public void F(TValue v) { }    // generics: 1, arg: TValue
    public void F(TValue v) { } // generics: 2, arg: TValue

    public void F(X v) { }    // generics: 1, arg: 0
    public void F(X v) { } // generics: 2, arg: 0
    public void F(Y v) { } // generics: 2, arg: 1
}
