CorString: IndexOfAny |
Reports the zero-based index of the first occurrence in s of any character in a specified array of Unicode characters. The search starts at a specified character position and examines a specified number of character positions.
Public Function IndexOfAny( ByRef s As String, ByRef OfAny As Variant, Optional ByRef StartIndex As Variant, Optional ByRef Count As Variant ) As Long
The search begins at StartIndex and continues to StartIndex + Count - 1. The character at StartIndex + Count is not included in the search.
Index numbering starts from zero. The StartIndex parameter can range from 0 to one less than the length of s.
The search for AnyOf is case-sensitive.
Exception | Condition |
---|---|
ArgumentNullException | AnyOf is uninitialized. |
ArgumentOutOfRangeException |
Count or StartIndex is negative. -or- Count + StartIndex is greater than the number of characters in s. |
The following example finds the index of the occurrence of any character of the string "aid" within a substring of another string.
