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; public class StringExercise { public static void Main() { string str; int length = 0; Console.Write("Input the string : "); str = Console.ReadLine(); foreach (char chr in str) { length += 1; } Console.Write("Length of the string is : {0}\n\n",length); Console.ReadLine(); } }
Result
