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

Definição

Quando substituído em uma classe derivada, retorna o Type do objeto englobado ou referenciado pelo tipo de matriz, ponteiro ou tipo de referência.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

Retornos

O Type do objeto englobado ou referenciado pelo tipo de referência, ponteiro ou matriz atual ou null se Type atual não é uma matriz ou um ponteiro ou não é passado por referência ou representa um tipo genérico ou um parâmetro de tipo na definição de um tipo genérico ou método genérico.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.

Exemplos

O exemplo a seguir demonstra o GetElementType uso do método.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:
