Example with a Rectangular Array

The following example shows the foreach statement used with a rectangular array:

class Sample
   {
      static void Main()
      {
         int nTotal = 0;
         int[,] arr1 = { {10, 11}, {12, 13} };
 
         foreach( int element in arr1 )
         {
            nTotal += element;
            Console.WriteLine
               ("Element: {0}, Current Total: {1}", 
                  element, nTotal);
         }
      }
   }

The output is the following:

Element: 10, Current Total: 10
Element: 11, Current Total: 21
Element: 12, Current Total: 33
Element: 13, Current Total: 46
