C# Can I add Interface methods to a list?

I just started programming and I dont even know if this is even possible...

I have the following Interface:

public interface ISkills
{
    int SelfHeal();
    int AditionDamage();
    int DoubleDamage();
    int DefenseMatrix();
}

and the following base class:

class NetNavi : ISkills
{
    List<ISkills> skills = new List<ISkills>();
     
    int ISkills.SelfHeal()
    {
        return 5;
    }

    int ISkills.AditionDamage()
    {
        return 5;
    }

    int ISkills.DoubleDamage()
    {
        return 5;
    }

    int ISkills.DefenseMatrix()
    {
        return 5;
    }
     
    
    public void AddSkills(int chosenSkill)
    {
        switch(chosenSkill)
        {
            case 1:
                //add SelfHeal to the list
                break;
            case 2:
                //add AditionDamage to the list
                break;
            case 3:
                //add DoubleDamage to the list
                break;
            case 4:
                //add DefenseMatrix to the list
                break;
        }
    }
}

In main the user gets asked to choose 2 skills. How can I add the chosen methods to my list (because the add() doesnt work...) and how can I call the methods in the list then?

Here:

class NetNavi : ISkills
    {
        Dictionary<string, Func<int>> skills = new Dictionary<string, Func<int>>();
     
        int SelfHeal()
        {
            return 5;
        }

        int AditionDamage()
        {
            return 5;
        }

        int DoubleDamage()
        {
            return 5;
        }

        int DefenseMatrix()
        {
            return 5;
        }
     
    
            
       

 public void AddSkills(int chosenSkill)
        {
            switch(chosenSkill)
            {
                case 1:
                    Func<int> theFunc = SelfHeal;
                    skills.Add("SelfHeal", theFunc);
                    break;
                case 2:
                    Func<int> theFunc = AditionDamage;
                    skills.Add("AditionDamage", theFunc);
                    break;
                case 3:
                    Func<int> theFunc = DoubleDamage;
                    skills.Add("DoubleDamage", theFunc);
                    break;
                case 4:
                    Func<int> theFunc = DefenseMatrix;
                    skills.Add("DefenseMatrix", theFunc );
                    break;
            }   
        }
}

In which by typing skills["DefenseMatrix"]() (or instead of "DefenseMatrix" any other key "key" you defined in skills.Add("key", theFunc);) you execute the method.

If there is no matching "key" found this will raise an error.

You can check if a key exists by if (skills.ContainsKey("key"))

If you actually just wanted to determine which methods the character is allowed to do and which not, you might benefit from looking into [Flags] enum's. It seems [Flags] would be a better way.
