c# - If a partial class inherits from a class then all other partial classes with the same name should also inherit the same base class?

Question

I have a class in Model in my MVC project like this.

public partial class Manager : Employee
{
    public string Name {get;set;}
    public int Age {get;set;}
}

And this class I have in App_Code folder in the same project. Now I want to know whether my this class is also need to get inherit from the Employee class or Not?

public partial class Manager 
{
    public void SaveEmployee();
}

I have to do this because my client want me to move all the methods in App_Code folder which are dealing with database.

And yes both these classes are sharing the same namespace.

Answer 1

That's a single class defined across multiple declarations, not two different classes. You only need to define the inheritance model in a single declaration, e.g.:

public class Foo { }

//Bar extends Foo
public partial class Bar : Foo { }

public partial class Bar {  }

However, if you were to try the following, you'd generate a compiler error of "Partial declarations of 'Bar' must not specify different base classes":

public class Foo { }

public partial class Bar : Foo { }

public partial class Bar : object {  }
