ApplicationId Class

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

Contains information used to uniquely identify an application. This class cannot be inherited.

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

[SerializableAttribute] 
[ComVisibleAttribute(true)] 
public sealed class ApplicationId
/** @attribute SerializableAttribute() */ 
/** @attribute ComVisibleAttribute(true) */ 
public final class ApplicationId
SerializableAttribute 
ComVisibleAttribute(true) 
public final class ApplicationId

An application identity consists of the publisher's public key, the application name, the target processor architecture, the application culture, and the application version. The application identity properties values correspond to information contained in the application manifest.

ApplicationId is used by the ApplicationSecurityInfo class to identify an application.

The following code example displays the ApplicationId properties by obtaining the ApplicationId from an ApplicationSecurityInfo instance created using the ActivationContext for the currently executing manifest-based application.

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.Demand, ControlDomainPolicy = true)]
        public static void Main(string[] args)
        {
            Console.WriteLine("Full name = " +
                AppDomain.CurrentDomain.ActivationContext.Identity.FullName);
            Console.WriteLine("Code base = " +
                AppDomain.CurrentDomain.ActivationContext.Identity.CodeBase);
            ApplicationSecurityInfo asi = new ApplicationSecurityInfo(AppDomain.CurrentDomain.ActivationContext);

            Console.WriteLine("ApplicationId.Name property = " + asi.ApplicationId.Name);
            if (asi.ApplicationId.Culture != null)
                Console.WriteLine("ApplicationId.Culture property = " + asi.ApplicationId.Culture.ToString());
            Console.WriteLine("ApplicationId.ProcessorArchitecture property = " + asi.ApplicationId.ProcessorArchitecture);
            Console.WriteLine("ApplicationId.Version property = " + asi.ApplicationId.Version);
            // To display the value of the public key, enumerate the Byte array for the property.
            Console.Write("ApplicationId.PublicKeyToken property = ");
            byte[] pk = asi.ApplicationId.PublicKeyToken;
            for (int i = 0; i < pk.GetLength(0); i++)
                Console.Write("{0:x}", pk[i]);

            Console.Read();
        }

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