Namespace:  System
Assembly:  Bridge (in Bridge.dll)

Type: System..::..String
startIndex
Type: System..::..Int32
The search starting position. The search proceeds from startIndex toward the beginning of this instance.
count
Type: System..::..Int32
The number of character positions to examine.

Return Value

The zero-based starting index position of value if that string is found, or -1 if it is not found or if the current instance equals Empty. If value is Empty, the return value is the smaller of startIndex and the last index position in this instance.

Exceptions
