Yield keyword in C# – Reduces LOC

Yield keyword is employed to reduce the allocation of arrays and by using a simple foreach iterative control structure.

Here’s a simple program which displays the first five even numbers.

 

   1: private void LearnYield_Click(object sender, EventArgs e)

   2:        {

   3:            // this is the main program

   4:            string result = String.Empty;

   5:  

   6:            foreach (int value in ShowEvenNum(2, 5))

   7:            {

   8:                result = result + " - " + value.ToString();

   9:            }

  10:  

  11:            MessageBox.Show(result);

  12:        }

  13:  

  14:        // this method returns the list of first five even numbers

  15:        public static IEnumerable<int> ShowEvenNum(int number, int multiplier)

  16:        {

  17:            int loopValue = 0;

  18:            int numberResult = 0;

  19:  

  20:            while (loopValue < multiplier)

  21:            {

  22:                numberResult += number;

  23:                loopValue++;

  24:  

  25:                // this yield keyword will directly add to the return list

  26:                yield return numberResult;

  27:            }

  28:  

  29:        }

This code and its comments are self explanatory.
