Mixed Inheritance of interfaces and Classes

If IBase is inherited by both the Base class and IA, does Class A inherited from Base and IA inherit the IBase?

Test result: Yes

So does it inherit from the implementation of the Base class or the implementation in IA?

Switch (Who Am I ?)

Case (Base) a: I inherited the implementation of the Base.

Case (IA) a: I inherited from IA implementation

Case (IBase) a: I inherited the implementation from IBase

Case a: whether the methods are declared. If so, the declaration takes priority; otherwise, it is the implementation of the parent class.

This result provides a possibility that the common function of sub-classes is implemented through the parent class, and then applied to all sub-interfaces through the parent interface, and the sub-classes can override the corresponding methods.

Test code:

Code
Namespace ubunturetesting
{
Internal class A: Base, IA, IBase
{
// Methods
Public ();
Void IBase. Write ();
}

Internal class Base: IBase
{
// Methods
Public Base ();
Public void Write ();
}

Public interface IA: IBase
{
}

Public interface IBase
{
// Methods
Void Write ();
}

Internal class InterfaceTesting
{
// Methods
Public InterfaceTesting ();
Public static void Run ();
}

Internal class Program
{
// Methods
Public Program ();
Private static void Main (string [] args );
}
}
