Description
Returns the position of a string in the list.
Call IndexOf to obtain the position of the first occurrence of the S string. IndexOf is not case-sensitive; this means that the given string may differ in case from the string in the list. For example:
String1 := MyStrings.Items.IndexOf('My First String');
is equivalent to
String1 := MyStrings.Items.IndexOf('My FIRST String');
IndexOf returns the 0-based index of the string. Thus, if S matches the first string in the list, IndexOf returns 0, if S is the second string, IndexOf returns 1, and so on. If the string is not in the string list, IndexOf returns -1.
Note: If the string appears in the list more than once, IndexOf returns the position of the first occurrence.
