Examples

The following code example shows how to obtain the current ActivationArguments object from the AppDomainSetup for the AppDomain of a manifest-based application.

using System.Collections;
using System.Text;
using System.Security.Policy;
using System.Reflection;
using System.Security;
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);
            Console.Read();
        }
    
        public void Run()
        {
            Main(new string[] { });
            Console.ReadLine();
        }
    }

Remarks

The ActivationArguments class is used by the AppDomainSetup class.

The manifest-based activation model uses an application manifest rather than an assembly for activation. A manifest fully describes the application, its dependencies, security requirements, and so forth. The manifest model has several advantages over the assembly-based activation model, especially for Web applications. For example, the manifest contains the security requirements of the application, which enables the user to decide whether to allow the application to execute before downloading the code. The manifest also contains information about the application dependencies.

Constructors

ActivationArguments(ActivationContext, String[])	Initializes a new instance of the ActivationArguments class with the specified activation context and activation data.
ActivationArguments(ActivationContext)	Initializes a new instance of the ActivationArguments class with the specified activation context.
ActivationArguments(ApplicationIdentity, String[])	Initializes a new instance of the ActivationArguments class with the specified application identity and activation data.
ActivationArguments(ApplicationIdentity)	Initializes a new instance of the ActivationArguments class with the specified application identity.

Properties

ActivationContext	Gets the activation context for manifest-based activation of an application.
ActivationData	Gets activation data from the host.
ApplicationIdentity	Gets the application identity for a manifest-activated application.

Methods

Clone()	Produces a copy of the current ActivationArguments object.
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Returns a string that represents the current object. (Inherited from Object)
