Parameters

key

The name of the item to find in the collection.

Return Value

The zero-based index of the first occurrence of the item with the specified key, if found; otherwise, -1.

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.

The Name property corresponds to the key for a ListViewItem in the ListView.ListViewItemCollection.

The key comparison is not case-sensitive. If the key parameter is a null reference (Nothing in Visual Basic) or an empty string, IndexOfKey returns -1.
