| Extension method: int LastIndexOf<T>(this IEnumerable<T>, Func<T, bool>)Declarationpublic static int LastIndexOf<T>(
this IEnumerable<T> source,
Func<T, bool> predicate
) Summary
Returns the index of the last element in this source satisfying the specified predicate. If no such elements are found, returns -1 . Generic type parametersT | This type parameter is not documented. |
Remarks
This method is optimised for the case in which the input sequence is a list or array. In all other cases, the
collection is evaluated completely before this method returns. |
