Visual Studio - C#

1.) Write a base class Student>that has two property members. name and contact and one method member: CalculateFinalGrade(). must be an Abstract class method must be by its child class. (1 point) For example, Student Property: StudentName Property: Contact Method: Calculate FinalGrade() } 2.) Write two child classes Undergraduate Student> and , both of which inherit Student and implement any abstract member. =90%; B: >=80% and 90%; C: >=70% and =60% and = 0.90 then finalGrade = "A" else if the Exam >= 0.80 then finalGrade = "B" return finalGrade } Note: 1.) You can have both to inherit and overrides the CalculateFinalGrade() in each of them. OR inherits Student> and inherits . That is, the CalculateFinalGrade()in Student> is overridden by the same method in its child class 2.) You can use either switch case... or if...else if. 3.) Use the classes in the above to implement the GradeCalculation program as follows. (2 points) In this program, you don't need to implement data validation (even though I did it in the demo program). Make sure to hide the Term Paper textbox when the undergraduate is selected. The demo program - LabAssignment-2.exe is located in the "LabAssignment-2" folder in the W drive.
