c# - Override a static method

Question

I am extending a new class by inheriting from RolesService. In RolesService I have a static methog that I would like to override in my newly derived class. When I make the call from my derived object it does not use the overridden static method it actually calls the base class method. Any ideas?

public class RolesService : IRolesService
{
    public static bool IsUserInRole(string username, string rolename)
    {
        return Roles.IsUserInRole(username, rolename);
    }
}

public class MockRoleService : RolesService
{
    public new static bool IsUserInRole(string username, string rolename)
    {
        return true;
    }
}

You can't override a static method. A static method can't be virtual, since it's not related to an instance of the class.

The "overriden" method in the derived class is actually a new method, unrelated to the one defined in the base class (hence the new keyword).
