    New to C#! Arguments to Private Variables

    Hello, right now i'm learning C# and I need some one to clarify what my teachers trying to say. We have to make a simple score sheet which I did but not the way he wanted, we're suppose to have Player One with x points which I did but this is the part I don't get.

    3 setName
    argument: name
    argument type: string
    return type: nothing
    Method sets the value of the private variable Name.

    You are suppose to assign the name arg to the private variable]

    If private string Name; is already defined and in the setName(){} wouldn't Name = "Player One" suffice? From my understanding Name is already set as a string before adding it in the function, so the argument would be: Name = "Player One", because there's no return for setName(){} it's a void. Nothing was defined if the function was suppose to be public or private so I made it public. And "Player One" would be the value for Name.

    Code:
    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Text;
    
    namespace ScoreSheet
    {
    
        class Player
        {
            private string Name;
            private float Score;
    
            public void setName()
            {
    
                Name = "Player One";
                
    
            }
    
    
            public string getName()
            {
    
                return Name;
            }
    
            public float addPoints(float points)
            {
    
                Score = points;
                return points;
            }
    
            public float getPoints()
            {
    
                
                return Score;
    
    
            }
    
        }
    
    
    
        class Program
        {
            static void Main(string[] args)
            {
    
                Player play = new Player();
    
                
                play.setName();
                play.getName();
                Console.WriteLine("Player One, your points are: " +  play.addPoints(10));
                play.getPoints();
                
    
            }
        }
    }

    Re: New to C#! Arguments to Private Variables

    You are suppose to pass in a method argument to the setName() method.

    Code:
    public void SetName(string name)
    {
      Name = name;
    }
    Hopefully, after completing this exercise, the instructor will point out that in C#, there is no need to create Setter and Getter methods (i.e. SetName/GetName) because in C#, there are something called [auto] properties which automatically create setters and getters for you under the covers.

    The corresponding auto property with a public setter and getter is:

    Code:
    public string Name { get; set; }
    As an aside, it would be nice if schools taught the standard coding convention for the language they are teaching in. In other words, in C#, method names are PascalCase, not camelCased (unlike in Java, where method names typically are pascalCased). So setName(...) should be declared as SetName(...).

    Thanks for the clear cut defination, I was thinking backwards it seems. The ironic part about this course is that we're learning C# before we get into unreal script. As for why he does setter/getters he mainly works in C++ so I guess he does it as close as possible to C++.

    That's good if the course ends you up in C++; otherwise, you kind of miss out on learning C#'s features.

    At any rate, glad I could help.
