foreach statement iterates over each element in an enumerable object.
Both an array and a string are enumerable.
The following code enumerates over the characters in a string, from the first character through to the last:
using System; class MainClass/*from w w w . j av a 2s . co m*/ { public static void Main(string[] args) { foreach (char c in "book2s.com") // c is the iteration variable Console.WriteLine (c); } }
