Searches the specified one-dimensional Array, returning the index of the last occurrence of the specified object between the specified index and the first element.
A int containing the index of the last occurrence of value in the range startIndex through the lower bound of array, if found; otherwise, array.GetLowerBound(0) - 1.Note: For a vector, if value is not found, the return value will be -1. This provides the caller with a standard code for the failed search.
Type Reason ArgumentNullException array is null. ArgumentOutOfRangeException startIndex is outside the range of valid indices for array. RankException array has more than one dimension.
This version of Array.LastIndexOf(Array, object) is equivalent to Array.LastIndexOf(Array, object)( array, value, startIndex,startIndex+ 1 -array.GetLowerBound(0)).
The elements are compared using object.Equals(object).
