Parameters

key
String

The key to search the collection for.

Returns

The zero-based index of the first occurrence of value within the entire collection, if found; otherwise, -1.

Remarks

If IndexOfKey is called successively, the last returned index will be checked for a key match first, and if there is no match, the search starts at the beginning of the collection.
