4.4.9. Iterating with "foreach"

There is an alternative loop command, similar to "for", but more adequate to iterate through certain data structures, such as the arrays (and other we will see).

It is used with the format "foreach (variable in SetOfValues)":

    int[] daysInMonth = {31, 28, 31};

    foreach(int days in daysInMonth)

    {

      Console.WriteLine("Days in the month: {0}", days);  

    }

   

    string[] names = {"Albert", "Andrew", "Anthony"};

    foreach(string name in names)

    {

      Console.Write(" {0}", name);  

    }

    Console.WriteLine();

   

    string greeting = "Hello";

    foreach(char letra in greeting)

    {

      Console.Write("{0}-", letra);  

    }

    Console.WriteLine();
