Návraty

Objekt Type zahrnující nebo odkazovaný aktuálním polem, ukazatelem nebo odkazovým typem, nebo null pokud proud Type není pole nebo ukazatel nebo není předán odkazem nebo představuje obecný typ nebo parametr typu v definici obecného typu nebo obecné metody.

Příklady

Následující příklad ukazuje použití GetElementType metody.

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:

    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:

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()

        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.
