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;
    }
}

Doing the following the will allow you to work around the static call. Where you want to use the code take an IRolesService via dependency injection then when you need MockRolesService you can pass that in.

public interface IRolesService
{
    bool IsUserInRole(string username, string rolename);
}

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

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