Introduction
I have used Visual Studio 2012 for debugging purpose. But you can use any version of visul studio as per your availability.
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
![Write a program in C# to display the characters and frequency of character from given string in LINQ Query](https://techstudys.com/wp-content/uploads/2021/07/7-18.png)
