ActivationContext Class

Identifies the activation context for the current application. This class cannot be inherited.

System.Object
  System.ActivationContext

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

[SerializableAttribute]
[ComVisibleAttribute(false)]
public sealed class ActivationContext : IDisposable, 
	ISerializable

The ActivationContext type exposes the following members.

  NameDescription
Public propertyApplicationManifestBytesGets the ClickOnce application manifest for the current application.
Public propertyDeploymentManifestBytesGets the ClickOnce deployment manifest for the current application.
Public propertyFormGets the form, or store context, for the current application.
Public propertyIdentityGets the application identity for the current application.

  NameDescription
Public methodStatic memberCreatePartialActivationContext(ApplicationIdentity)Initializes a new instance of the ActivationContext class using the specified application identity.
Public methodStatic memberCreatePartialActivationContext(ApplicationIdentity, String[])Initializes a new instance of the ActivationContext class using the specified application identity and array of manifest paths.
Public methodDisposeReleases all resources used by the ActivationContext.
Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

The ActivationContext class contains an ApplicationIdentity and provides internal-only access to the application manifest. The activation context is used during manifest-based activation to set up the domain policy and provide an application-based security model. For more information, see the ApplicationSecurityManager class.

Important noteImportant

This type implements the IDisposable interface. When you have finished using the type, you should dispose of it either directly or indirectly. To dispose of the type directly, call its Dispose method in a try/catch block. To dispose of it indirectly, use a language construct such as using (in C#) or Using (in Visual Basic). For more information, see the “Using an Object that Implements IDisposable” section in the IDisposable interface topic.

The following code example demonstrates the use of an ActivationContext object to obtain the ApplicationIdentity for a manifest-based application. For correct results, execute this code example as a manifest-based application.

        public static void Main(string[] args)
        {
            ActivationContext ac = AppDomain.CurrentDomain.ActivationContext;
            ApplicationIdentity ai = ac.Identity;
            Console.WriteLine("Full name = " + ai.FullName);
            Console.WriteLine("Code base = " + ai.CodeBase);

            Console.Read();
        }
        [SecurityPermission(SecurityAction.LinkDemand, ControlDomainPolicy=true)]
        public void Run()
        {
            Main(new string[] { });
            Console.ReadLine();
        }
    }
}
