Beispiele

Das folgende Beispiel ruft die Feldinformationen der Felder von MyClass ab, bestimmt, ob die Felder serialisiert werden können, und zeigt die Ergebnisse an.

using namespace System;
using namespace System::Reflection;
using namespace System::Runtime::Serialization;

public ref class MyClass
{
public:
   short myShort;

   // The following field will not be serialized.  

   [NonSerialized]
   int myInt;
};

int main()
{
   // Get the type of MyClass.
   Type^ myType = MyClass::typeid;

   // Get the fields of MyClass.
   array<FieldInfo^>^myFields = myType->GetFields( static_cast<BindingFlags>(BindingFlags::Public | BindingFlags::NonPublic | BindingFlags::Instance | BindingFlags::Static) );
   Console::WriteLine( "\nDisplaying whether or not the field is serializable.\n" );

   // Display whether or not the field is serializable.
   for ( int i = 0; i < myFields->Length; i++ )
      if ( myFields[ i ]->IsNotSerialized )
            Console::WriteLine( "The {0} field is not serializable.", myFields[ i ] );
      else
            Console::WriteLine( "The {0} field is serializable.", myFields[ i ] );
}

        for(int i = 0; i < myFields.Length; i++)
            if(myFields[i].IsNotSerialized)

Hinweise

Die IsNotSerialized -Eigenschaft gibt zurück true , wenn das Feld mit dem FieldAttributes.NotSerialized Flag gekennzeichnet ist. Wenn dieses Flag für ein Feld festgelegt ist, gibt dies an, dass das Feld nicht serialisiert werden muss, wenn der Typ entfernt wird.
