How do I extract the contents of an array without knowing the size of the array?

It is possible to get the upper and lower bounds of an array by using the UBound and the LBound functions, but it is faster and easier to extract the array information without these functions.

The following snippet of code displays each element of the array aFoo using a 'For Each...Next' loop.

'Create the aFoo array
Dim aFoo
aFoo = Array("Hello", "Aplus!", "How ", "are ", "you?")

Dim iItem

For Each iItem in aFoo
Response.Write iItem & "<BR>"
Next

The above code will produce the following output (when viewed through a browser):

Hello
Aplus!
How
are
you?

This example loops through each element in the array. If there are no more elements in the array, the loop will end.

Another approach is to extract the contents from an array using a 'For ... Next' Loop. Furthermore, if you want all of the array's contents in a single string, you can use the join function. For an example of using both of these techniques, go to the FAQ article: How can I display all of the contents of a single-dimension array?
