Object.GetType-Methode
Ruft den Type der aktuellen Instanz ab.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Syntax
'Declaration
Public Function GetType As Type
'Usage
Dim instance As Object
Dim returnValue As Type
returnValue = instance.GetType
public Type GetType ()
public:
Type^ GetType ()
public Type GetType ()
public function GetType () : Type
Rückgabewert
Die Type-Instanz, die den exakten Laufzeittyp der aktuellen Instanz darstellt.
Hinweise
Für zwei Objekte x und y mit identischen Laufzeittypen gibt Object.ReferenceEquals(x.GetType(),y.GetType())true zurück.
Das Type-Objekt macht die der Klasse des aktuellen Object zugeordneten Metadaten verfügbar.
Beispiel
Das folgende Beispiel veranschaulicht, dass GetType den Laufzeittyp der aktuellen Instanz zurückgibt.
using System;
public class MyBaseClass: Object {
}
public class MyDerivedClass: MyBaseClass {
}
public class Test {
public static void Main() {
MyBaseClass myBase = new MyBaseClass();
MyDerivedClass myDerived = new MyDerivedClass();
object o = myDerived;
MyBaseClass b = myDerived;
Console.WriteLine("mybase: Type is {0}", myBase.GetType());
Console.WriteLine("myDerived: Type is {0}", myDerived.GetType());
Console.WriteLine("object o = myDerived: Type is {0}", o.GetType());
Console.WriteLine("MyBaseClass b = myDerived: Type is {0}", b.GetType());
}
