Type.GetElementType Metoda

Definice

Pokud je přepsáno v odvozené třídě, vrátí objekt, který je Type zahrnut nebo na který odkazuje aktuální pole, ukazatel nebo odkazový typ.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 ();
public abstract Type? GetElementType ();
abstract member GetElementType : unit -> Type
Public MustOverride Function GetElementType () As Type

Návraty

Type

Objekt, který je zahrnut Type nebo odkazován aktuálním typem pole, ukazatel nebo odkaz, nebo null Pokud aktuální Type není pole nebo ukazatel, nebo není předáno odkazem nebo představuje obecný typ nebo parametr typu v definici obecného typu nebo obecné metody.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.

Příklady

Následující příklad ukazuje použití 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

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