Ejemplos

En el ejemplo de código siguiente se muestra el uso de la SynchronizationAttribute tipo.The following code example demonstrates the use of the SynchronizationAttribute type.

using System;
using System.EnterpriseServices;
using System.Reflection;

// References:
// System.EnterpriseServices

// This is equivalent to [Synchronization(SynchronizationOption.Required)].
[Synchronization]
public class SynchronizationAttribute_Ctor : ServicedComponent
{
}

[Synchronization(SynchronizationOption.Disabled)]
public class SynchronizationAttribute_Ctor_SynchronizationOption : ServicedComponent
{
}

[Synchronization(SynchronizationOption.RequiresNew)]
public class SynchronizationAttribute_Value : ServicedComponent
{
    public void ValueExample()
    {
        // Get the SynchronizationAttribute applied to the class.
        SynchronizationAttribute attribute =
            (SynchronizationAttribute)Attribute.GetCustomAttribute(
            this.GetType(),
            typeof(SynchronizationAttribute),
            false);

        // Display the value of the attribute's Value property.
        Console.WriteLine("SynchronizationAttribute.Value: {0}",
            attribute.Value);
    }
}

Transacciones y activación de just-in-time (JIT) habilite la sincronización automáticamente.Both transaction and just-in-time (JIT) activation enable synchronization automatically.

Aplicar SynchronizationAttribute a un objeto de contexto enlazado a la creación de una espera auto y el identificador de evento de restablecimiento, que no sean de manera determinista recolectado.Applying SynchronizationAttribute to a context-bound object results in the creation of a wait handle and auto reset event, which are not deterministically garbage collected. Por lo tanto, no debería crear un gran número de objetos enlazados por contexto marcado con el SynchronizationAttribute dentro de un breve período de tiempo.Therefore, you should not create a large number of context-bound objects marked with the SynchronizationAttribute within a short time period.
