Solution 2

Here is how class C need to be implement both interfaces:

C#

class C : A, B
        {
            public void A.show()
            {// Some Code
            }

            public void B.show()
            {// Some Code
            }
        }

If a class implements two interfaces with the same method define in it, then in effect there is only one method, and they are not distinguishable. And if two methods has the same return type - it is simply a compilation error.

Though you can do something like (implementing the interface explicitly),

C#

class C : A, B
{
    public void A.show()
    {
    }
    
    public void B.show()
    {
    }
}

Read the MSDN documentation: https://msdn.microsoft.com/en-us/library/ms173157.aspx[^]
And a quite good article: http://www.c-sharpcorner.com/UploadFile/rohatash/inherit-multiple-interfaces-with-the-same-method-name-in-C-Sharp/[^]
