Ausnahmen

Diese Eigenschaft wird von .NET Compact Framework derzeit nicht unterstützt.

Beispiele

Im folgenden Beispiel wird der Handle des entsprechenden Typs zurückgegeben und der Handle an eine Methode übergeben, die den Typ vom Handle abruft und es anzeigt.

using namespace System;
using namespace System::Reflection;
ref class MyClass
{
public:
   int myField;
};

void DisplayTypeHandle( RuntimeTypeHandle myTypeHandle )
{
   
   // Get the type from the handle.
   Type^ myType = Type::GetTypeFromHandle( myTypeHandle );
   
   // Display the type.
   Console::WriteLine( "\nDisplaying the type from the handle:\n" );
   Console::WriteLine( "The type is {0}.", myType );
}

int main()
{
   try
   {
      MyClass^ myClass = gcnew MyClass;
      
      // Get the type of MyClass.
      Type^ myClassType = myClass->GetType();
      
      // Get the runtime handle of MyClass.
      RuntimeTypeHandle myClassHandle = myClassType->TypeHandle;
      DisplayTypeHandle( myClassHandle );
   }
   catch ( Exception^ e ) 
   {
      Console::WriteLine( "Exception: {0}", e->Message );
   }

}

    public int myField = 10;

Hinweise

TypeHandle Kapselt einen Zeiger auf eine interne Datenstruktur, die den Typ darstellt. Dieser Handle ist während der Prozesslebensdauer eindeutig. Das Handle ist nur in der Anwendungsdomäne gültig, in der sie abgerufen wurde.
