A class can implement multiple interfaces.

public class A : Ix, Iy,Iz

This way you can achieve multiple inheritence

In C#, a class cannot have multiple inheritance with classes. But class can have multiple inheritance with one class and more than one interface.

Eg:

namespace TestClass

{

public class A

{

public void testA()

{

Console.WriteLine("In Class A");

}

}

interface IB

{

void testIB();

}

interface IC

{

void testIC();

}

public class Test : A, IB, IC

{

public void testIB()

{

Console.WriteLine("In Interface IB");

}

public void testIC()

{

Console.WriteLine("In Interface IC");

}

}

class Program

{

static void Main(string[] args)

{

Test tt = new Test();

tt.testA();

tt.testIB();

tt.testIC();

Console.ReadLine();

}

}

}
