List(Of T).FindLastIndex Method (Int32, Predicate(Of T))
Searches for an element that matches the conditions defined by the specified predicate, and returns the zero-based index of the last occurrence within the range of elements in the List(Of T) that extends from the first element to the specified index.
Assembly: mscorlib (in mscorlib.dll)
'Declaration Public Function FindLastIndex ( _ startIndex As Integer, _ match As Predicate(Of T) _ ) As Integer
- Type: System.Int32
The zero-based starting index of the backward search.
Return ValueType: System.Int32
The zero-based index of the last occurrence of an element that matches the conditions defined by match, if found; otherwise, –1.
The List(Of T) is searched backward starting at startIndex and ending at the first element.
The Predicate(Of T) is a delegate to a method that returns true if the object passed to it matches the conditions defined in the delegate. The elements of the current List(Of T) are individually passed to the Predicate(Of T) delegate.
This method performs a linear search; therefore, this method is an O(n) operation, where n is the number of elements from the beginning of the List(Of T) to startIndex.
