List<T>.Reverse Methode

Definition

Überlädt

Beispiele

Im folgenden Beispiel werden beide über Ladungen der- Reverse Methode veranschaulicht.The following example demonstrates both overloads of the Reverse method. Im Beispiel wird eine von Zeichen folgen erstellt List<T> und sechs Zeichen folgen hinzugefügt.The example creates a List<T> of strings and adds six strings. Die Reverse() -Methoden Überladung wird zum Umkehren der Liste verwendet, und anschließend Reverse(Int32, Int32) wird die-Methoden Überladung verwendet, um die Mitte der Liste umzukehren, beginnend mit Element 1 und umfasst vier Elemente.The Reverse() method overload is used to reverse the list, and then the Reverse(Int32, Int32) method overload is used to reverse the middle of the list, beginning with element 1 and encompassing four elements.
