Does C# support multiple inheritance?

Question

A colleague and I are having a bit of an argument over multiple inheritance. I\'m saying it\'s not supported and he\'s saying it is. So, I thought that I\'d ask the brainy

Answer 1

You can't inherit multiple classes at a time. But there is an options to do that by the help of interface. See below code

interface IA
{
    void PrintIA();
}

class  A:IA
{
    public void PrintIA()
    {
        Console.WriteLine("PrintA method in Base Class A");
    }
}

interface IB
{
    void PrintIB();
}

class B : IB
{
    public void PrintIB()
    {
        Console.WriteLine("PrintB method in Base Class B");
    }
}

public class AB: IA, IB
{
    A a = new A();
    B b = new B();

    public void PrintIA()
    {
       a.PrintIA();
    }

    public void PrintIB()
    {
        b.PrintIB();
    }
}

you can call them as below

AB ab = new AB();
ab.PrintIA();
ab.PrintIB();
