Question

How can i implement a method from a class that is extended to an Interface?

I have this Interface:

public Interface myInterface
{
      public static int myMethod();
}

And this class:

public class MyClass : myInterface
{
       // And I want here to implement the method form myInterface and i don't know how
}

Interface won’t compile – change it to interface.
static can’t be part of an interface.

After corrections the code would look like this for example:

public interface myInterface
{
      int myMethod();
}

public class MyClass : myInterface
{
       public int myMethod()
       {
           return 1;
       }
}

Regarding static and interface see a quote from http://channel9.msdn.com/forums/TechOff/250972-Static-Inheritance/?CommentID=274217 :

Inheritance in .NET works only on instance base. Static methods are defined on the type level not on the instance level. That is why
overriding doesn’t work with static methods/properties/events…

Static methods are only held once in memory. There is no virtual table etc. that is created for them.

If you invoke an instance method in .NET, you always give it the current instance. This is hidden by the .NET runtime, but it happens.
Each instance method has as first argument a pointer (reference) to
the object that the method is run on. This doesn’t happen with static
methods (as they are defined on type level). How should the compiler
decide to select the method to invoke?
