ActivationContext Class

.NET Framework 2.0

Other Versions

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

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

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

Syntax

C++

Copy

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

Copy

/** @attribute SerializableAttribute() */ 
/** @attribute ComVisibleAttribute(false) */ 
public final class ActivationContext implements IDisposable, ISerializable

JScript

Copy

SerializableAttribute 
ComVisibleAttribute(false) 
public final class ActivationContext implements IDisposable, ISerializable

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.

Example

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.

Copy

using System;
using System.Collections;
using System.Text;
using System.Security.Policy;
using System.Reflection;
using System.Security;
using System.Security.Permissions;

namespace ActivationContextSample
{
    public class Program : MarshalByRefObject
    {
        [SecurityPermission(SecurityAction.LinkDemand, ControlDomainPolicy=true)]
        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();
        }
    }
}
