In this tutorial you will learn how to use the for loop to repeat sections of code in the C# language. For loops are useful for when you want to repeat code a certain number of times. They are also very useful for efficiently working through all the elements in an array or going through each character in a string. For loops have a built in counter, condition, and increment. Watch the video below and then scroll down for the sample code.

Sample code

Example 1 – using for loop as simple simple counted loop

using System;

namespace MyCSharpProject
{
  class Program
  {
    static void Main(string[] args)
    {
      for (int i = 0; i < 10; i++)
      {
        Console.WriteLine("Counter is: " + i);
      }
      Console.ReadLine();
    }
  }

}

Example 2 – using for loop to go through each character in string

using System;

namespace MyCSharpProject
{
  class Program
  {
    static void Main(string[] args)
    {
      string word = "dog";
      for (int i = 0; i < word.Length; i++)
      {
        if (word[i] == 'a')
        {
          Console.WriteLine("This word contains the letter a");
        }
      }
      Console.ReadLine();
    }
  }

}
