System Namespace Array Class
Initializes a new instance of the Array class.
1. Creates a one-dimensional Array of the specified Type and length, with zero-based indexing.
2. Creates a multidimensional Array of the specified Type and dimension lengths, with zero-based indexing.
3. Creates a two-dimensional Array of the specified Type and dimension lengths, with zero-based indexing.
4. Creates a multidimensional Array of the specified Type and dimension lengths, with the specified lower bounds.
5. Creates a three-dimensional Array of the specified Type and dimension lengths, with zero-based indexing.
The following code example shows how to create and initialize a three-dimensional Array.
NOTE: This example shows how to use one of the overloaded versions of CreateInstance. For other examples that might be available, see the individual overload topics.
