Programming Exercise 4: Classes - Methods

Define a Deactivate() method in your existing User class. Calling this method will set its status field to Inactive.

This is the expected output when using your class:

class Program
{
  static void Main(string[] args)
  {
      User user = new User("jtamad", "jtamad");
      Console.WriteLine(user.IsActive);  // Outputs "True" (default value)
      user.Deactivate();
      Console.WriteLine(user.IsActive);  // Outputs "False"
      Console.ReadLine();
  }
}

Define another method, GetCopy(), that allows the class to return a copy of itself. Hint: Use the MemberwiseClone() method inherited from System.Object. You also need to perform a cast to the appropriate User object as this method returns a System.Object type.

After implementing this, you should be able to use your class as follows:

class Program
{
    static void Main(string[] args)
    {
        User user1 = new User("jtamad", "jtamad");
        Console.WriteLine(user1.UserID);  // Outputs "jtamad"

        User user2 = user1;               // user2 references the
                                          // same object as user1
        user2.UserID = "juantamad";       // Modifies user1 also
                                          // since user2 references
                                          // the same object as user1
        Console.WriteLine(user1.UserID);  // Outputs "juantamad

        user2 = user1.GetCopy();          // user2 has its own copy
                                          // of a User object copied
                                          // from user1
        user2.UserID = "jtamad";          // Does not affect user1
                                          // since this is a new object
        Console.WriteLine(user1.UserID);  // Outputs "juantamad"
        Console.WriteLine(user2.UserID);  // Outputs "jtamad"

        Console.ReadLine();
    }
}
