[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]
Reports the zero-based index position of the last occurrence of a specified string within this instance. The search starts at a specified character position and proceeds backward toward the beginning of the string.
Assembly: mscorlib (in mscorlib.dll)
- Type: System..::..String
The string to seek.
- Type: System..::..Int32
The search starting position. The search proceeds from startIndex toward the beginning of this instance.
Index numbering starts from zero. That is, the first character in the string is at index zero and the last is at Length - 1.
The search begins at the startIndex character position of this instance and proceeds backward toward the beginning until either value is found or the first character position has been examined. For example, if startIndex is Length - 1, the method searches every character from the last character in the string to the beginning.
