        base.Add(TCKimlikNo, AdSoyAd);
    }

Answer 1

Make the Add method protected instead of internal.

Answer 2

If you want classes that inherit from your base class to have access to the Add(...) method, but nothing external to that, then you need to mark it as protected, such that:

public  abstract class MyBaseClass
{
    private Dictionary<string, string> dic { get; set; }

    public MyBaseClass()
    {

    }

    protected void Add(string key, string value)
    {
        dic.Add(key, value);
    }
}


public class MyClass1 : MyBaseClass
{
    public MyClass1()
        : base()
    {

    }

    public void Save(string TCKimlikNo, string AdSoyAd)
    {
        base.Add(TCKimlikNo, AdSoyAd);
    }
}

This way, only classes that inherit from MyBaseClass will be able to access Add(...).

Answer 3

I think you are wanting to use the Protected keyword instead of internal.
