.net - Class and Interface in C# -



.net - Class and Interface in C# -

i have interface named imyinterface contains 4 methods method1,method2,method3,method4 , having 2 classes named base class , derived class, have implement method1,method2 in base of operations class , method3,method4 in derived class.

how possible can 1 help me

it's pretty simple, should declare base of operations class abstract , mark method3 , method4 abstract in , implement them in derived class. here's sample implementation:

interface imyinterface { void method1(); void method2(); void method3(); void method4(); } abstract class baseclass : imyinterface { public void method1() { } public void method2() { } public abstract void method3(); public abstract void method4(); } class derivedclass : baseclass { public override void method3() { } public override void method4() { } }

c# .net
