C# Anonymous Interface Implementation

C# Anonymous Interface Implementation

In C#, you can create an anonymous type that implements an interface by using the new keyword and defining the interface members inline. Here's an example:

public interface IMyInterface
{
    void DoSomething();
}

public class MyClass
{
    public void MyMethod()
    {
        // create an instance of an anonymous type that implements IMyInterface
        var myObject = new { DoSomething = (Action)(() => Console.WriteLine("Doing something!")) };

        // call the DoSomething method on the anonymous object
        myObject.DoSomething();
    }
}

In this example, we're defining an interface IMyInterface with a single method DoSomething. We then create a new instance of an anonymous type that implements IMyInterface by defining the DoSomething method inline using a lambda expression. We cast the lambda expression to an Action delegate to match the method signature of DoSomething. Finally, we call the DoSomething method on the anonymous object.

Note that anonymous types are read-only and cannot be cast to other types, so you'll need to define all of the necessary interface members inline. Also, anonymous types are typically used for ad-hoc data structures and are not intended to be used as long-lived objects.
