 abstract Type ^ GetElementType();

public abstract Type GetElementType ();

public abstract Type? GetElementType ();

abstract member GetElementType : unit -> Type

Public MustOverride Function GetElementType () As Type

Retours

Type de l’objet englobé ou auquel le tableau, pointeur ou type référence actuel fait référence, ou null si le Type actuel n’est pas un tableau ou un pointeur, ou n’est pas passé par référence ou représente un type générique ou un paramètre de type dans la définition d’un type ou d’une méthode générique.

Exemples

L’exemple suivant illustre l’utilisation de la GetElementType méthode .

using namespace System;
public ref class TestGetElementType{};

int main()
{
   array<Int32>^array = {1,2,3};
   Type^ t = array->GetType();
   Type^ t2 = t->GetElementType();
   Console::WriteLine( "The element type of {0} is {1}.", array, t2 );
   TestGetElementType^ newMe = gcnew TestGetElementType;
   t = newMe->GetType();
   t2 = t->GetElementType();
   Console::WriteLine( "The element type of {0} is {1}.", newMe, t2 == nullptr ? "null" : t2->ToString() );
}

/* This code produces the following output:

The element type of System.Int32[] is System.Int32.
The element type of TestGetElementType is null.
 */

using System;
class TestGetElementType
{
    public static void Main()
    {
        int[] array = {1,2,3};
        Type t = array.GetType();
        Type t2 = t.GetElementType();
        Console.WriteLine("The element type of {0} is {1}.",array, t2.ToString());
        TestGetElementType newMe = new TestGetElementType();
        t = newMe.GetType();
        t2 = t.GetElementType();
        Console.WriteLine("The element type of {0} is {1}.", newMe, t2==null? "null" : t2.ToString());
    }
}

/* This code produces the following output:

The element type of System.Int32[] is System.Int32.
The element type of TestGetElementType is null.
 */

type TestGetElementType() = class end
do
    let array = [| 1; 2; 3 |]
    let t = array.GetType()
    let t2 = t.GetElementType()
    printfn $"The element type of {array} is {t2}."
    
    let newMe = TestGetElementType()
    let t = newMe.GetType()
    let t2 = t.GetElementType()
    printfn $"""The element type of {newMe} is {if t2 = null then "null" else string t2}."""

(* This code produces the following output:

The element type of System.Int32[] is System.Int32.

Class TestGetElementType

    Public Shared Sub Main()
        Dim array As Integer() = {1, 2, 3}
        Dim t As Type = array.GetType()
        Dim t2 As Type = t.GetElementType()
        Console.WriteLine("The element type of {0} is {1}.", array, t2.ToString())
        Dim newMe As New TestGetElementType()
        t = newMe.GetType()
        t2 = t.GetElementType()
        If t2 Is Nothing Then
            Console.WriteLine("The element type of {0} is {1}.", newMe, "null")
        Else
            Console.WriteLine("The element type of {0} is {1}.", newMe, t2.ToString())
        End If
    End Sub
End Class

' This code produces the following output:
'
'The element type of System.Int32[] is System.Int32.
'The element type of TestGetElementType is null.

Remarques

Cette méthode retourne null pour la Array classe .
