using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
 
namespace CharacterOccurrenceApp
{
    class Program
    {
        static void Main(string[] args)
        {
            string Statement = string.Empty;
 
            Console.WriteLine("Enter a string to check occurrence of a character numbers");
 
            Statement = Console.ReadLine();
            Statement = Statement.ToLower();
 
            if (Statement.Length > 0)
            {
                while (Statement.Length > 0)
                {
                    int CountCharacter = 0;
                    Console.Write("Number of Occurance of '" + Statement[0] + "': ");
                   
                    //Checking the Character occurrence in the string entered by the user
                    for (int i = 0; i < Statement.Length; i++)
                    {
                        if (Statement[0] == Statement[i])
                        {
                            CountCharacter++;
                        }
                    }
 
                    //Count of each character
                    Console.Write(CountCharacter + "\n");
 
                    //Removing that character from the string
                    Statement = Statement.Replace(Statement[0].ToString(), string.Empty);
                }
            }
            Console.ReadLine();
        }
    }
}

Run the application and enter the string value then press "Enter" key then see the output.
