Understanding Equals() method

/* 
Exercise 10-3A

Create an application named JobDemo that declares and uses Job objects. The Job class holds job information for a home repair service. The class has five properties that include:

    JobNumber - The job number - int
    Customer - The customer name - string
    Description - The job description - string
    Hours - The estimated hours - double
    price - The price for the job

Create a constructor that requires parameters for all the data except price. Follow the order and data type above. Include auto-implemented properties for the job number, customer name, and job description, but not for hours or price; the price field value is calculated as estimated hours times $45.00 ($45.00 / hour) whenever the hours value is set.

Also create the following methods for theJob class:

    An Equals() method that determines two Jobs are equal if they have the same job number
    A GetHashCode() method that returns the job number
    A ToString() method that returns a string containing all job information in the following format:

Job 111 Smith exterior paint 20 hours @$45.00 per hour. Total price is $900.00

The JobDemo application declares a few Job objects, sets their values, and demonstrates that all the methods work as expected.

info> In order to prepend the $ to currency values, the program will need to use the CultureInfo.GetCultureInfo method. In order to do this, include the statement using System.Globalization; at the top of your program and format the output statements as follows: WriteLine("This is an example: {0}", value.ToString("C", CultureInfo.GetCultureInfo("en-US")));
