Use Find to obtain the index in a sorted list where the string S should be added.

If the string S, or a string that differs from S only in case when CaseSensitive is false, already exists in the list, Find returns true. If the list does not contain a string that matches S, Find returns false. The index where S should go is returned in the Index parameter.

The value of Index is zero-based, where the first string has the index 0, the second string has the index 1, and so on. Note: Only use Find with sorted lists. For unsorted lists, use the IndexOf method instead. Collapse All. When the application runs, a string list object is created and three strings are added to it. Create; try MyList.
