Create a class called StudentGrades. This class should be designed based off the following UML Diagram:

class StudentGrades

-double list grades_list

+

+AddGrade(double): void

+RemoveGrade(double): bool

+GetClassAverage(): double

+GetHighestGrade(): double

+GetLowestGrade(): double

- creates an empty array for the grades_list array.

AddGrade Adds the passed in grade to the list. Note that any number that is NOT 0 100 should be rejected.

RemoveGrade Removes the first occurrence of the passed in grade from the list. If the grade is not found, the method should return false.

GetClassAverage() Average the grades in the list and return the average.

GetHighestGrade - Find and return the highest grade in the list.

GetLowestGrade Find and return the lowest grade in the list.

I need help with this program by manually doing all the methods on a list class and in c# programming
