System_CAPS_pubmethodLastIndexOf(Char, Int32)

Reports the zero-based index position of the last occurrence of a specified Unicode character within this instance. The search starts at a specified character position and proceeds backward toward the beginning of the string.

System_CAPS_pubmethodLastIndexOf(Char, Int32, Int32)

Reports the zero-based index position of the last occurrence of the specified Unicode character in a substring within this instance. The search starts at a specified character position and proceeds backward toward the beginning of the string for a specified number of character positions.

System_CAPS_pubmethodLastIndexOf(String)

Reports the zero-based index position of the last occurrence of a specified string within this instance.

System_CAPS_pubmethodLastIndexOf(String, Int32)
