| Description |
A new string is built containing an interleaving of all strings in a string array ValueArray with a fixed Separator string.
A subset of array strings may be used by starting at Start index, for Count strings (see the second example).
|
| | Notes | Very Important : Methods in .Net treat strings as starting at 0, unlike traditional Delphi where they started at 1. Likewise arrays (our example defines an array starting at 0, but an array starting at 1 or more will still be treated as a zero-indexed array by the Join method).
