例

次の例では、MyClass のフィールドのフィールド情報を取得し、フィールドをシリアル化できるかどうかを判断し、結果を表示します。

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 ] );
}

using System;
using System.Reflection;
using System.Runtime.Serialization;

public class MyClass

    public short myShort;

    // The following field will not be serialized.
    [NonSerialized()]
    public int myInt;

    public static void Main()
    {
        // Get the type of MyClass.
        Type myType = typeof(MyClass);

        // Get the fields of MyClass.
        FieldInfo[] myFields = myType.GetFields(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 not serializable.", myFields[i]);

注釈

IsNotSerializedフィールドが フラグでマークされている場合、 プロパティは をFieldAttributes.NotSerialized返trueします。 フィールドにこのフラグを設定すると、型がリモート化されるときにフィールドをシリアル化する必要がないことを示します。
