Try this: using System; using System.Collections.Generic; class Student { public string Name {get; set;} public int Grade {get; set;} public Student(string name int grade) { Name = name; Grade = grade; } } class Program { static void Main() { List list = new List (); Console.WriteLine(Enter student data); while(true) { Console.Write(
 Name (or q to end) : ); string name = Console.ReadLine(); if (name.ToLower() == q) break; int grade; bool isValid; do { Console.Write( Grade 0 to 30 : ); isValid = int.TryParse(Console.ReadLine() out grade); } while(!isValid || grade 30); Student s = new Student(name grade); list.Add(s); } int count = 0; foreach(Student s in list) { if (s.Grade > 20) count++; } Console.WriteLine(
{0} out of {1} students have marks greater than 20 count list.Count); Console.ReadKey(); } }
