Reverse<T>(T[])

Hiermee wordt de volgorde van de elementen in de eendimensionale algemene matrix omgekeerd.
Reverse<T>(T[], Int32, Int32)

Parameters

array

index
Int32

De beginindex van de sectie die u wilt omkeren.

length
Int32

Het aantal elementen in de sectie dat moet worden omgekeerd.

Uitzonderingen

ArgumentNullException

array is null.

RankException

ArgumentOutOfRangeException

index is kleiner dan de ondergrens van array.

– of –

length is kleiner dan nul.

ArgumentException

index en length geef geen geldig bereik op in array.

Voorbeelden

In het volgende codevoorbeeld ziet u hoe u het soort waarden in een bereik met elementen in een Arrayomkeren.

open System

let printIndexAndValues (arr: 'a []) =
    for i = arr.GetLowerBound 0 to arr.GetUpperBound 0 do
        printfn $"\t[{i}]:\t{arr[i]}"

// Creates and initializes a new Array.
let myArray = 
    [| "The"; "QUICK"; "BROWN"; "FOX"
       "jumps"; "over"; "the"; "lazy"; "dog" |]

// Displays the values of the Array.
printfn "The Array initially contains the following values:" 
printIndexAndValues myArray 

// Reverses the sort of the values of the Array.
Array.Reverse(myArray, 1, 3)

// Displays the values of the Array.
printfn "After reversing:"
printIndexAndValues myArray

 This code produces the following output.

Opmerkingen

Na een aanroep van deze methode gaat het element op myArray[i], waar i zich een index in de matrix bevindt, naar myArray[j], waar j is gelijk aan (myArray.Length + myArray.GetLowerBound(0)) - (i - myArray.GetLowerBound(0)) - 1.

De Reverse methode kan worden gebruikt om een gelabelde matrix om te keren.

Deze methode is een O(n)-bewerking, waarbij n .length

Van toepassing op

Reverse(Array)

Hiermee wordt de volgorde van de elementen in het hele eendimensionale Arrayelement omgekeerd.

Opmerkingen

Na een aanroep van deze methode gaat het element op myArray[i], waar i zich een index in de matrix bevindt, naar myArray[j], waar j is gelijk aan (myArray.Length + myArray.GetLowerBound(0)) - (i - myArray.GetLowerBound(0)) - 1.

Deze methode is een O(n)-bewerking, waarbij n de Length van array.

In F# kan de functie Array.rev worden gebruikt.

Zoals in het volgende voorbeeld wordt weergegeven, kan de Reverse methode worden gebruikt om een gelabelde matrix om te draaien. Hiermee initialiseert u een onregelmatige matrix met één element voor elke maand van het huidige jaar in de kalender van de huidige cultuur. Elk element bevat een matrix met zoveel elementen als die maand dagen heeft. In het voorbeeld wordt de inhoud van de matrix weergegeven, wordt de methode aangeroepen Reverse en wordt vervolgens de inhoud van de omgekeerde matrix weergegeven.
