Registers a specified object type on the service end as a type that can be activated on request from a client.

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

[SecurityPermissionAttribute(SecurityAction.Demand, Flags = SecurityPermissionFlag.RemotingConfiguration)]
public static void RegisterActivatedServiceType(
	Type type
)

Parameters

type
Type: System.Type

The Type of object to register.

Exception Condition
SecurityException

At least one of the callers higher in the callstack does not have permission to configure remoting types and channels.

To create an instance of a client-activated object on the server, you must know its Type and it must be registered on the server end by using the RegisterActivatedServiceType method. To obtain a proxy for a new instance of the client-activated object, the client must first register a channel with ChannelServices and then activate the object by calling new or Activator.CreateInstance.

To activate a client-activated object type with the new keyword, you must first register the object type on the client end using the RegisterActivatedClientType method. Calling the RegisterActivatedClientType method gives the remoting infrastructure the location of the remote application, where new attempts to create it. If, on the other hand, you use the CreateInstance method to create a new instance of the client-activated object, you must supply the remote application's URL as a parameter, so no prior registration on the client end is necessary. To supply the CreateInstance method with the URL of the server where you want to create the object, you must encapsulate the URL in an instance of the UrlAttribute class.

For a detailed description of client-activated objects, see [<topic://cpconClientActivation>].

The following code example demonstrates registration of an object type on the server as a type that can be activated by the client. For the client code that corresponds to the presented server code, see the example for the RegisterActivatedClientType method.

using System;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;

public class ServerClass {

    public static void Main()  {

        ChannelServices.RegisterChannel(new TcpChannel(8082));

        RemotingConfiguration.RegisterActivatedServiceType(typeof(HelloServiceClass));

        Console.WriteLine("Press enter to stop this process.");
        Console.ReadLine();
    }
}

The following code example shows the service object registered in the sample code above.

using System;

public class HelloServiceClass : MarshalByRefObject {

    static int n_instance;

    public HelloServiceClass() {
        n_instance++;
        Console.WriteLine(this.GetType().Name + " has been created.  Instance # = {0}", n_instance);
    }


    ~HelloServiceClass() {
        Console.WriteLine("Destroyed instance {0} of HelloServiceClass.", n_instance);
        n_instance --;
    }


    public String HelloMethod(String name) {

        // Reports that the method was called.
        Console.WriteLine();
        Console.WriteLine("Called HelloMethod on instance {0} with the '{1}' parameter.", 
                             n_instance, name);

        // Calculates and returns the result to the client.
        return "Hi there " + name + ".";
    }
}
