Abstract class and Interface

Yes, you can inherit from an abstract class and implement an interface at the same time.

Here's a simple example:

using System;

interface IFace

{

void SomeMethod();

}

abstract class Abstract

{

public abstract void SomeMethod2();

}

class MyClass: Abstract, IFace

{

public void SomeMethod()

{

Console.WriteLine("Hello from SomeMethod");

}

public override void SomeMethod2()

{

Console.WriteLine("Hello from SomeMethod2");

}

class Test

{

static void Main()

{

MyClass mc = new MyClass();

mc.SomeMethod();

mc.SomeMethod2();

Console.ReadKey();

}
