    Newb question. I am just begining to use C#

    Hello guys,

    I am just starting to use C# for school. I like the program so far but I have lots to learn. I am having problems with properties. This is an assignment for school but I don't know how to do it.

    I need to know how to code the properties.
    This is the code so far:
    namespace Assignment2
    {
    public class Student
    {
    public Student(string n)
    {
    Name = n;
    Record = new Transcript();
    }
    // To do: Property implementation
    public string Name;
    public Transcript Record;
    public double GPA
    {
    get
    {
    return Record.GPA;
    }
    }
    public int WealthPoints = 10000;
    public int PridePoints = 100;
    }
    }

    then I'm given a table to add some properties?
    this is what the table looks like:
    Student
    -m_record : Transcript
    -m_name : string
    -m_wealth : int = 1000
    -m_pride : int = 100
    + Student(string);
    +Name : string
    +WealthPoints : int
    +PridePoints : int
    +GPA : double
    +Record: Transcript

    Any advice would be really helpful. Thanks.

    Sometimes it makes sense to encapsulate data by making the main state of an object hidden, but accessible through properties. For example, suppose I wanted to represent a person with a name (string) and age (int). I might write:

    Code:
    public class Person
    {
        //Declare private variables; accessible only within this class
        private string name;
        private int age;
    
        //Constructor
        public Person(string newName, int newAge)
        {
            this.name = newName;
            this.age = newAge;
        }
    
        //Properties
    
        //Other classes can both get and set a Person's name
        public string Name
        {
            //Defines a getter method; always named get
            get { return this.name; }
    
            /*Define a setter method; always named set
             *The setter method will accept an argument (in this case a string)
             * that will be stored in a reserved variable (keyword) called value
            set { this.name = value; }
        }
    
        //But let's only let them get (NOT modify) age
        public int Age
        {
            //Define the getter
            get { return this.name; }
    
            //But omit the setter
        }
    }
    Make sense?
