List<T>.FindLastIndex Method (Int32, Predicate<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<T> that extends from the first element to the specified index.
Assembly: mscorlib (in mscorlib.dll)
- 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<T> is searched backward starting at startIndex and ending at the first element.
The Predicate<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<T> are individually passed to the Predicate<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<T> to startIndex.
