Question

Create a class that might provides a property for an instance variable based on the example in this question.

Here is the example:

// Fig. 4.7: GradeBook.cs
2 // GradeBook class that contains a courseName instance variable,
3 // and a property to get and set its value.
4 using System;
5
6 public class GradeBook
7 {
8 private string courseName; // course name for this GradeBook
9
10 // property to get and set the course name
11 public string CourseName
12 {
13 get
14 {
15 return courseName;
16 } // end get
17 set
18 {
19 courseName = value;
20 } // end set
21 } // end property CourseName
22
23 // display a welcome message to the GradeBook user
24 public void DisplayMessage()
25 {
26 // use property CourseName to get the
27 // name of the course that this GradeBook represents
28 Console.WriteLine( "Welcome to the grade book for {0}!",
29 ); // display property CourseName
30 } // end method DisplayMessage
31 } // end class GradeBook

Explanation / Answer

Below is the main class where how to use the above class is given:

class Program
    {
        static void Main(string[] args)
        {
            GradeBook Book1 = new GradeBook();
            Book1.CourseName="A Couse Name";
            Book1.DisplayMessage();
            Console.ReadKey(true);
        }
    }

There is a small error in you given code at line 28 and 29, you missed to include the variable - it should be as follows:

Console.WriteLine( "Welcome to the grade book for {0}!",courseName ); // display property CourseName
