Esempio

Nell'esempio di codice seguente viene illustrato come ottenere l'oggetto corrente ActivationArguments da AppDomainSetup per l'oggetto AppDomain di un'applicazione basata su manifesto.

using System.Runtime.Hosting;

namespace ActivationContextSample
{
    public class Program : MarshalByRefObject
    {
        public static void Main(string[] args)
        {
            // Get the AppDomainManager from the current domain.
            AppDomainManager domainMgr = AppDomain.CurrentDomain.DomainManager;
            // Get the ApplicationActivator from the AppDomainManager.
            ApplicationActivator appActivator = domainMgr.ApplicationActivator;
            Console.WriteLine("Assembly qualified name from the application activator.");
            Console.WriteLine(appActivator.GetType().AssemblyQualifiedName);
            // Get the ActivationArguments from the SetupInformation property of the domain.
            ActivationArguments activationArgs = AppDomain.CurrentDomain.SetupInformation.ActivationArguments;
            // Get the ActivationContext from the ActivationArguments.
            ActivationContext actContext = activationArgs.ActivationContext;
            Console.WriteLine("The ActivationContext.Form property value is: " +
                activationArgs.ActivationContext.Form);

Commenti

La ActivationArguments classe viene utilizzata dalla AppDomainSetup classe .

Il modello di attivazione basato su manifesto usa un manifesto dell'applicazione anziché un assembly per l'attivazione. Un manifesto descrive in modo completo l'applicazione, le relative dipendenze, i requisiti di sicurezza e così via. Il modello manifesto presenta diversi vantaggi rispetto al modello di attivazione basato su assembly, in particolare per le applicazioni Web. Ad esempio, il manifesto contiene i requisiti di sicurezza dell'applicazione, che consente all'utente di decidere se consentire l'esecuzione dell'applicazione prima di scaricare il codice. Il manifesto contiene anche informazioni sulle dipendenze dell'applicazione.
