Using foreach with Arrays

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.WriteLine(i);

}

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 } };

foreach (int i in numbers2D)

{

System.Console.Write("{0} ", i);

}

The output of this example is:

9 99 3 33 5 55

However, with multidimensional arrays, using a nested for loop gives you more control over the array elements.
