How can I implement multiple interfaces in C#?

How can I implement multiple interfaces in C#?

In C#, you can implement multiple interfaces by separating them with commas in the class declaration. For example:

public class MyClass : IFirstInterface, ISecondInterface

Can you give me an example of a class implementing two interfaces?

Sure! Here's a simple example:

public interface IFirstInterface {
    void MethodA();
}

public interface ISecondInterface {
    void MethodB();
}

public class MyClass : IFirstInterface, ISecondInterface {
    public void MethodA() {
        Console.WriteLine("Method A from IFirstInterface");
    }

    public void MethodB() {
        Console.WriteLine("Method B from ISecondInterface");
    }
}

What happens if the interfaces have methods with the same name?

If the interfaces have methods with the same name, you need to explicitly implement one of them to avoid ambiguity. You can do this by using explicit interface implementation.

Can you show me how to do explicit interface implementation?

Certainly! Here's how you can implement methods explicitly:

public class MyClass : IFirstInterface, ISecondInterface {
    void IFirstInterface.MethodA() {
        Console.WriteLine("Method A from IFirstInterface");
    }

    void ISecondInterface.MethodA() {
        Console.WriteLine("Method A from ISecondInterface");
    }
}
