ApplicationId Class

Contains information used to uniquely identify a manifest-based application. This class cannot be inherited.

System.Object
  System.ApplicationId

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)
[SerializableAttribute]
[ComVisibleAttribute(true)]
public sealed class ApplicationId

The ApplicationId type exposes the following members.

  Name Description
Public method ApplicationId Initializes a new instance of the ApplicationId class.
Top
  Name Description
Public property Culture Gets a string representing the culture information for the application.
Public property Name Gets the name of the application.
Public property ProcessorArchitecture Gets the target processor architecture for the application.
Public property PublicKeyToken Gets the public key token for the application.
Public property Version Gets the version of the application.

  Name Description
Public method Copy Creates and returns an identical copy of the current application identity.
Public method Equals Determines whether the specified ApplicationId object is equivalent to the current ApplicationId. (Overrides Object.Equals(Object).)
Protected method Finalize Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public method GetHashCode Gets the hash code for the current application identity. (Overrides Object.GetHashCode().)
Public method GetType Gets the Type of the current instance. (Inherited from Object.)
Protected method MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Public method ToString Creates and returns a string representation of the application identity. (Overrides Object.ToString().)

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. For more information about the application manifest, see ClickOnce Application Manifest.

ApplicationId is used by the ApplicationSecurityInfo class to identify a manifest-based 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();
        }
    }
}
