Exemples

L’exemple suivant obtient les informations de champ des champs de MyClass, détermine si les champs peuvent être sérialisés et affiche les résultats.The following example gets the field information of the fields of MyClass, determines if the fields can be serialized, and displays the results.

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 ] );

Remarques

La IsNotSerialized propriété retourne true lorsque le champ est marqué avec l' FieldAttributes.NotSerialized indicateur.The IsNotSerialized property returns true when the field is marked with the FieldAttributes.NotSerialized flag. Lorsque cet indicateur est défini sur un champ, cela indique qu’il n’est pas nécessaire de sérialiser le champ lorsque le type est distant.When this flag is set on a field, it indicates that the field does not have to be serialized when the type is remoted.
