Question

Can we implement interface without overriding some of its method.I heard this is possible in some cases.I came across this question recently while interview.

Answer 1

You can inherit the implementation from a base class, if that’s what you were thinking of:

interface IFoo
{
    void Bar();
}

class Parent
{
    public void Bar() {}
}

class Child : Parent, IFoo {}

If that’s not it though, I don’t know what you’re thinking of.
