Using C# create a NumberList class. This class will need to keep track of a list of any number of floating-point values and be able to perform operations on these values. Use a private Listfield to keep track of the numbers. For more information on List, see the Week 8 lecture slides and chapter 8 of the textbook. The NumberList class will have the following methods . void Add (float number) This method adds number to the end of the list. If myList is a NumberList containing 1, 23 calling myList.Add (3) will mean that myList now contains 1, 2, 3) . List Numbers () This method returns a list containing all the numbers in the NumberList. As you should be should iust return that List using a private List to keep track of these numbers anyway, this method float Minimum() This method returns the lowest number in the list. . float Maximum() This method returns the highest number in the list. float Sum This method returns the sum of all numbers in the list. If myList Is a Numberlist containing 1, 2, 3) calling myList.Sum) will return6 . float Average() This method returns the average/mean of all numbers in the list. If myList is a NumberList containing 1, 2, 3) calling myList.Sum() will return 2, as the sum of those numbers is 6 and 6 divided by 3 (the number of numbers in the list) is 2 int Count() This method returns the number of numbers in the list. If myList is a NumberList containing 1, 2, 3) calling myList.Count) will return 3 . int DeleteBelow(float threshold) This method removes from the list all numbers that are below threshold. If myList is a NumberList containing {1, 2, 3) calling myList.DeleteBelow (1.5) will remove 1, leaving just {2, 3)
