Parameters

array

A one-dimensional Array to search. [Edit]

value

A object to locate in array. [Edit]

startIndex

A int that contains the index at which searching starts. [Edit]

Returns

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.

[Edit]

Exceptions

Type	Reason
ArgumentNullException	array is null. [Edit]
ArgumentOutOfRangeException	startIndex is outside the range of valid indices for array. [Edit]
RankException	array has more than one dimension. [Edit]

Remarks

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).
