Find the Number of Occurrences of a Character in a String using C#

In this blog I shall demonstrate the number of occurrences of a character in a string.

I hope this article remember our school days programming.

Code

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace SchoolDays

{

class Program

{

static void Main(string[] args)

{

string input = "WWW.C-SHARPCORNER.COM";

while (input.Length > 0)

{

Console.Write(input[0] + " : ");

int count = 0;

for (int j = 0; j < input.Length; j++)

{

if (input[0] == input[j])

{

count++;

}

}

Console.WriteLine(count);

input = input.Replace(input[0].ToString(),string.Empty);

}

Console.ReadLine();

}

}

}

Each time a character count is found then that character is removed from the string for the next iteration.
