Call Abstract Constructor in Another Time - C#

Hello,

I have two classes. Can I call the abstract constructor after a modified argument in an extended class? For example:

namespace OOPAdventure;

public abstract class Character
{
    public String Name { get; }
    public Character(string name) => Name = name;
}



namespace OOPAdventure;

public class Player : Character
{
    public Player(string name) : base(name)
    {
        name = name.Remove(2);
        // NOW, Can I send modified 'name' to the Charecter class?
    }
}

In your particular case, try this:

public class Player : Character
{
    public Player( string name ) : base( name.Remove( 2 ) )
    {
    }
}

Thank you, So in general we cannot call the constructor of the abstract class later and after the modified parameter?

According to language specifications, I do not think that it is possible to call the base constructor explicitly, but if you add a protected setter, you can do something like this:

public abstract class Character { public String Name { get; protected set; } public Character( ) { } } public class Player : Character { public Player( string name ) { name = name.Remove( 2 ); Name = name; } }

In new C# you can also use a public String Name { get; init; } definition to limit the usage of the setter.
