CSC139 Chapter 11 Lab Assignments;Objectives;In this lab assignment, students will learn;- How to define LINQ statement;- How to use LINQ to query data from object array;Goals;In this lab assignment, students will demonstrate the abilities to;- Define LINQ statement;- Use LINQ to query data from object array;Grading rubric;Category;High Proficiency;Medium Proficiency;Low Proficiency;Define the LINQ which get all scores in ascending order [40 pts];Successfully define the LINQ which get all scores in ascending order. [40ts];LINQ statement works, however, does not generate correct results. [20?39 pts];LINQ statement is not defined correctly. [0-19 pts];Define the LINQ which get all students who passed the exam [40 pts];Successfully define the LINQ which get all students who passed the exam. [40ts];LINQ statement works, however, does not generate correct results. [20-39 pts];LINQ statement is not defined correctly. [0-19 pts];Define the code to display the LINQ results correctly (20 pts);Successfully define the code to display the LINQ results correctly. [20 pts];The results can be displayed, however, some data or format are not correct. [10-19 pts];Results can not be displayed, or most data or formats are not correct. [0-9 pts];Create a console application ?LINQGradeBook?;Add the following class definition;Public Class GradeBook;Private nameValue As String;Private scoreValue As Integer;Public Sub New (ByVal n As String, ByVal s As Integer);nameValue = n;scoreValue = s;End Sub;Public Property Name() As String;Get;Return nameValue;End Get;Set (ByVal value As String);nameValue = value;End Set;End Property;Public Property Score() As Integer;Get;Return scoreValue;End Get;Set (ByVal value As Integer);scoreValue = value;End Set;End Property;Public Sub displayGradeBook();Console.WriteLine("Name: " & Name & vbTab & "Score: " & Score);End Sub;End Class;Rename the file ?Module1.vb? to ?LINQGradeBookTester.vb?;Complete the missing code following the comments. You are required to create two LINQ statements which will select specific gradeBook object from a GradeBook objects array.;Option Strict On;Module LINQGradeBookTester;Sub Main();Dim g1 As New GradeBook("AAA", 70);Dim g2 As New GradeBook("BBB", 50);Dim g3 As New GradeBook("CCC", 100);Dim g4 As New GradeBook("DDD", 80);add g1, g2, g3 and g4 in a array and display all student scores;Dim gradeBooks As GradeBook() = {g1, g2, g3, g4};display(gradeBooks, "Scores for all students: ");create a LINQ which get all scores in ascending order and display them.;create a LINQ which get all students who passed the exam;display number of passed students, their names and scores;End Sub;display gradeBook's information;Private Sub display(ByVal gradeBooks As IEnumerable, ByVal header As String);Console.WriteLine(header);For Each g As GradeBook In gradeBooks;g.displayGradeBook();Next;Console.WriteLine();End Sub;End Module;Here is output: (See next page)
