in C# i need to Write the program BookExceptionDemo for the Peterman Publishing Company. Create a BookException class that is instantiated when a Book’s price exceeds 10 cents per page and whose constructor requires three arguments for title, price, and number of pages. Create an error message that is passed to the Exception class constructor for the Message property when a Book does not meet the price-to-pages ratio. For example, an error message: For Goodnight Moon, ratio is invalid. ...Price is $12.99 for 25 pages. Next, create a Book class that contains fields for title, author, price, and number of pages. Include properties for each field. Throw a BookException if a client program tries to construct a Book object for which the price is more than 10 cents per page. Finally, using the Book class, create an array of five Books. Prompt the user for values for each Book. To handle any exceptions that are thrown because of improper or invalid data entered by the user, set the Book’s price to the maximum of 10 cents per page. At the end of the program, display all the entered, and possibly corrected, records. 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"))); code so far is using System; using static System.Console; using System.Globalization; class BookExceptionDemo { static void Main() { // Your code here } }
