WebJun 30, 2011 · When copying between multidimensional arrays, the array behaves like a long one-dimensional array, where the rows (or columns) are conceptually laid end to end So when you try to copy the original array to the new one, it just copies one memory location to the other, which gives, in one-dimensional representation: WebThe example above can be read like this: for each string element (called i - as in index) in cars, print out the value of i. If you compare the for loop and foreach loop, you will see that the foreach method is easier to write, it does not require a counter (using the Length property), and it is more readable.
