The name of the tab page to find in the collection.
The zero-based index of the first occurrence of a tab page 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 TabPage in the TabControl.TabPageCollection. The key comparison is not case-sensitive. If the key parameter is null or an empty string, IndexOfKey returns -1.
