Examples

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.

using System;

namespace ActivationContextSample
{
    public class Program : MarshalByRefObject
    {
        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();
        }

        public void Run()
        {
            Main(new string[] { });
            Console.ReadLine();
        }
    }
}

        Dim ac As ActivationContext = AppDomain.CurrentDomain.ActivationContext
        Dim ai As ApplicationIdentity = ac.Identity
        Console.WriteLine("Full name = " + ai.FullName)
        Console.WriteLine("Code base = " + ai.CodeBase)
        Console.Read()
    
    End Sub

    <SecurityPermission(SecurityAction.LinkDemand, ControlDomainPolicy:=True)> _
    Public Sub Run() 
        Main(New String() {})
        Console.ReadLine()
    
    End Sub
End Class

Remarks

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

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.

Properties

ApplicationManifestBytes	Gets the ClickOnce application manifest for the current application.
DeploymentManifestBytes	Gets the ClickOnce deployment manifest for the current application.
Form	Gets the form, or store context, for the current application.
Identity	Gets the application identity for the current application.

Methods

CreatePartialActivationContext(ApplicationIdentity, String[])	Initializes a new instance of the ActivationContext class using the specified application identity and array of manifest paths.
CreatePartialActivationContext(ApplicationIdentity)	Initializes a new instance of the ActivationContext class using the specified application identity.
Dispose()	Releases all resources used by the ActivationContext.
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
Finalize()	Enables an ActivationContext object to attempt to free resources and perform other cleanup operations before the ActivationContext is reclaimed by garbage collection.
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)

Explicit Interface Implementations

ISerializable.GetObjectData(SerializationInfo, StreamingContext)

Populates a SerializationInfo with the data needed to serialize the target object.
