Type.GetElementType Type.GetElementType Type.GetElementType Type.GetElementType Method

Definicja

Gdy jest zastępowany w klasie pochodnej, zwraca Type obiekt, do którego odnosi się odwołanie lub którego dotyczy bieżąca tablica, wskaźnik lub typ referencyjny.When overridden in a derived class, returns the Type of the object encompassed or referred to by the current array, pointer or reference type.

public:
 abstract Type ^ GetElementType();
public abstract Type GetElementType ();
abstract member GetElementType : unit -> Type
Public MustOverride Function GetElementType () As Type

Zwraca

Obiekt, do którego odnosi się lub odwołuje się bieżąca tablica, wskaźnik lub typ referencyjny lub null Jeśli bieżąca Type nie jest tablicą lub wskaźnikiem albo nie jest przekazana przez odwołanie lub reprezentuje typ ogólny lub parametr typu w Type Definicja typu ogólnego lub metody ogólnej.The Type of the object encompassed or referred to by the current array, pointer, or reference type, or null if the current Type is not an array or a pointer, or is not passed by reference, or represents a generic type or a type parameter in the definition of a generic type or generic method.

Przykłady

Poniższy przykład ilustruje użycie GetElementType metody.The following example demonstrates using the GetElementType method.

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.
 */
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 'TestGetElementType

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