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 characters and frequency of character from given string in LINQ Query
using System;
using System.Linq;
using System.Collections.Generic;
class LinqExercise
{
static void Main(string[] args)
{
string str;
Console.WriteLine("Input the string : ");
str = Console.ReadLine();
var Frequency = from x in str
group x by x into y
select y;
Console.Write("The frequency of the characters are :\n");
foreach (var Arr in Frequency)
{
Console.WriteLine("Character " + Arr.Key + ": " + Arr.Count() + " times");
}
Console.ReadLine();
}
}
Result
