List<T>.Reverse Método

Definição

Sobrecargas

Exemplos

O exemplo a seguir demonstra as duas sobrecargas do Reverse método . O exemplo cria uma List<T> de cadeias de caracteres e adiciona seis cadeias de caracteres. A Reverse() sobrecarga do método é usada para reverter a lista e, em seguida, a sobrecarga do Reverse(Int32, Int32) método é usada para reverter o meio da lista, começando com o elemento 1 e abrangendo quatro elementos.

    dinosaurs->Add("Pachycephalosaurus");

    dinosaurs->Add("Mamenchisaurus");
    dinosaurs->Add("Amargasaurus");
    dinosaurs->Add("Coelophysis");
    dinosaurs->Add("Oviraptor");

    Console::WriteLine();
    for each(String^ dinosaur in dinosaurs)
    {

    dinosaurs->Reverse();

    Console::WriteLine();
    for each(String^ dinosaur in dinosaurs)
