Write C#.NET program to find the length of string without using library function

Introduction

In one of forum, someone asked to Write C#.NET program to find the length of string without using library function. So in this snippet we will see to find the length of string without using any built-in library function or string function.

using System;
namespace DotNetMirror
{
    class StringLengthWithOutLibraryFunction
    {
        static void Main()
        {
            string normalStr = "DotNetMirror";
            int charCount = 0;
            foreach (char chr in normalStr)
            {
                charCount = charCount + 1;
            }
            Console.WriteLine("string '{0}' length is: {1}",normalStr,charCount);
            Console.ReadKey();
        }
    }
}

Output:
