C# inheritance: implements + extends

Question

Is it possible to do something like that in C#:

public class MyClass implements ClassA extends ClassB 
{

}

I need this because: I have two classes one of which is an Interface which I will be implementing in my class, but I would like to also use methods from another class, that does some stuff that I would like to use in my class.

Answer 1

C# doesn't support multiple inheritance. You can derive from one class and use interfaces for your other needs.

Syntax:

class MyClass : Foo, IFoo, IBar { }  interface IFoo { }  interface IBar { }  class Foo { } 

Answer 2

Try this one:

using System;  public interface A {     void DoSmth(); }  public class B {     public void OpA() { }     public void OpB() { } }  public class ClassC : B, A {     public void DoSmth(){} } 

Remember, you cannot inherit from two classes at specific class level, it could be only one class and any number of interfaces.

Answer 3

It should look like this:

public class MyClass: ClassB, InterfaceA{
}

ClassB is the base class.

InterfaceA is an interface.

You can only extend one base class, but you can implement many interfaces.

Answer 4

    class Base
    {
    }

    interface I1
    {
    }

    interface I2
    {
    }

    class Derived : Base, I1, I2
    {
    }

    static void Main(String[] args)
    {

        Derived d = new Derived();
    }
