C# Sharp Exercises: Find the nth Maximum Grade Point achieved by the students from the list of student
C# Sharp LINQ : Exercise-14 with Solution
Write a program in C# Sharp to find the n-th Maximum grade point achieved by the students from the list of students.
Sample Solution:-
C# Sharp Code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
public class Students
{
public string StuName { get; set; }
public int GrPoint { get; set; }
public int StuId { get; set; }
public List<Students> GtStuRec()
{
List<Students> stulist = new List<Students>();
stulist.Add(new Students { StuId = 1, StuName = " Joseph ", GrPoint = 800 });
stulist.Add(new Students { StuId = 2, StuName = "Alex", GrPoint = 458 });
stulist.Add(new Students { StuId = 3, StuName = "Harris", GrPoint = 900 });
stulist.Add(new Students { StuId = 4, StuName = "Taylor", GrPoint = 900 });
stulist.Add(new Students { StuId = 5, StuName = "Smith", GrPoint = 458 });
stulist.Add(new Students { StuId = 6, StuName = "Natasa", GrPoint = 700 });
stulist.Add(new Students { StuId = 7, StuName = "David", GrPoint = 750 });
stulist.Add(new Students { StuId = 8, StuName = "Harry", GrPoint = 700 });
stulist.Add(new Students { StuId = 9, StuName = "Nicolash", GrPoint = 597 });
stulist.Add(new Students { StuId = 10, StuName = "Jenny", GrPoint = 750 });
return stulist;
}
}
class LinqExercise14
{
static void Main(string[] args)
{
Students e= new Students();
Console.Write("\nLINQ : Find the nth Maximum Grade Point achieved by the students from the list of student : ");
Console.Write("\n------------------------------------------------------------------------------------------\n");
Console.Write("Which maximum grade point(1st, 2nd, 3rd, ...) you want to find : ");
int grPointRank = Convert.ToInt32(Console.ReadLine());
Console.Write("\n");
var stulist = e.GtStuRec();
var students = (from stuMast in stulist
group stuMast by stuMast.GrPoint into g
orderby g.Key descending
select new
{
StuRecord = g.ToList()
}).ToList();
students[grPointRank - 1].StuRecord
.ForEach(i => Console.WriteLine(" Id : {0}, Name : {1}, achieved Grade Point : {2}",i.StuId, i.StuName, i.GrPoint));
Console.ReadKey();
}
}
Sample Output:
LINQ : Find the nth Maximum Grade Point achieved by the students fro m the list of student : -------------------------------------------------------------------- ---------------------- Which maximum grade point(1st, 2nd, 3rd, ...) you want to find : 3 Id : 7, Name : David, achieved Grade Point : 750 Id : 10, Name : Jenny, achieved Grade Point : 750
