Using foreach with Arrays (C# Programming Guide)
C# also provides the foreach statement. This statement provides a simple, clean way to iterate through the elements of an array. For example, the following code creates an array called numbers and iterates through it with the foreach statement:
int[] numbers = { 4, 5, 6, 1, 2, 3, -2, -1, 0 };
foreach (int i in numbers)
{
System.Console.Write("{0} ", i);
}
//Output: 4 5 6 1 2 3 -2 -1 0
With multidimensional arrays, you can use the same method to iterate through the elements, for example:
int[,] numbers2D = new int[3, 2] { { 9, 99 }, { 3, 33 }, { 5, 55 } };
// Or use the short form:
// int[,] numbers2D = { { 9, 99 }, { 3, 33 }, { 5, 55 } };
foreach (int i in numbers2D)
{
System.Console.Write("{0} ", i);
}
// Output: 9 99 3 33 5 55
However, with multidimensional arrays, using a nested for loop gives you more control over the array elements.
