Introduction
I have used Visual Studio 2012 for debugging purpose. But you can use any version of visul studio as per your availability.
Write a program in C# to display the number and frequency of number from given array in LINQ Query
using System;
using System.Linq;
using System.Collections.Generic;
class LinqExercise
{
static void Main(string[] args)
{
int[] arr = new int[] { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 4, 5, 2, 3, 10 };
Console.Write("The numbers in the array are : \n");
Console.Write("1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 4, 5, 2, 3, 10 \n");
var n = from x in arr
group x by x into y
select y;
Console.WriteLine("\nThe number and the frequency are : \n");
foreach (var arrno in n)
{
Console.WriteLine("Number " + arrno.Key + " appears " + arrno.Count() + " times");
}
Console.ReadLine();
}
}
Result
