Clearing a multidimensional array?

Ken

Hi. I have this array defined:

public static string[,,] collections = new string[2, 201, 5];

..and I want to be sure it's empty when I call my readconfig function. I see there is Array.Clear, which you pass Array array, int index and int length. Does that mean I have to do:

Array.Clear(collections, 0, 2);
Array.Clear(collections, 1, 201);
Array.Clear(collections, 2, 5);

or is there a different / proper way to do it? Thanks!

The number of elements to be cleared wraps from dimension to dimension in a multi-dimensional array. So, the correct way to clear all the elements is as follows:

Array.Clear(collections, 0, 2 * 201 * 5);
Console.WriteLine(collections[1, 200, 4] == null); // true
