ActivationArguments Class

Note: This class is new in the .NET Framework version 2.0.

Provides data for manifest-based activation of an application. This class cannot be inherited.

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

<SerializableAttribute> _
<ComVisibleAttribute(True)> _
Public NotInheritable Class ActivationArguments
Dim instance As ActivationArguments

/** @attribute SerializableAttribute() */ 
/** @attribute ComVisibleAttribute(true) */ 
public final class ActivationArguments
public final class ActivationArguments

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.

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

        Dim domainMgr As AppDomainManager = AppDomain.CurrentDomain.DomainManager
        ' Get the ApplicationActivator from the AppDomainManager.
        Dim appActivator As ApplicationActivator = domainMgr.ApplicationActivator
        Console.WriteLine("Assembly qualified name from the application activator.")
        Dim ac As ActivationContext = AppDomain.CurrentDomain.ActivationContext
        ' Get the ActivationArguments from the SetupInformation property of the domain.
        Dim activationArgs As ActivationArguments = AppDomain.CurrentDomain.SetupInformation.ActivationArguments
        ' Get the ActivationContext from the ActivationArguments.
        Dim actContext As ActivationContext = activationArgs.ActivationContext
        Console.WriteLine("The ActivationContext.Form property value is: " + _

    End Sub 'Main

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

    End Sub 'Run
End Class 'Program
