Implement an interface consuming and returning the same interface in C#

 Implement an interface consuming and returning the same interface in C#

Here's an example of how you could implement an interface in C# that consumes and returns the same interface:

public interface IMyInterface
{
    IMyInterface DoSomething(IMyInterface input);
}
public class MyClass : IMyInterface
{
    public IMyInterface DoSomething(IMyInterface input)
    {
        // Implementation goes here
        return input;
    }
}

In this example, the IMyInterface interface defines a single method DoSomething that takes an instance of the same interface as an input parameter and returns the same interface. The MyClass implements the IMyInterface interface and provides an implementation for the DoSomething method.

With this implementation, you can now create instances of the MyClass and call the DoSomething method on them, passing instances of the IMyInterface as arguments and receiving instances of the IMyInterface as results.
