Answer / sheetal

Offcourse it works if you remove the interface. What is the
purpose of interface is : if you implementing any interface
you need to define all the methods declare in interface in
your class. In this code snippet implement the interface
and do define method in class and compile the program. It
will give you compile time error.

Interface IMyInterface
{
public void MyMethod();
}

class MyClass : IMyInterface
{
//DO NOT DEFINE MyMethod()
}
