注解

当前类由 RemotingConfiguration.RegisterActivatedServiceType 方法使用，该方法是该方法的服务器端对应项 RemotingConfiguration.RegisterActivatedClientType 。 该方法 RegisterActivatedServiceType 在服务器上用于允许指定对象类型的客户端进行远程激活。

若要在服务器上创建客户端激活的对象，必须知道该 Type对象，并且必须使用该方法在服务器端 RegisterActivatedServiceType 注册该对象。 若要获取新客户端激活对象的代理，客户端必须先向 ChannelServices 该通道注册通道，然后通过调用 new 或 Activator.CreateInstance激活该对象。

若要使用 new 关键字激活客户端激活的对象类型，必须先使用 RegisterActivatedClientType 该方法在客户端上注册对象类型。 通过调用 RegisterActivatedClientType ，可以向远程基础结构提供远程应用程序的位置，以便 new 尝试创建远程应用程序。 另一方面， CreateInstance 如果使用该方法创建客户端激活对象的新实例，则必须提供远程应用程序的 URL 作为参数，因此不需要在客户端上预先注册。 若要向方法提供 CreateInstance 要在其中创建对象的服务器的 URL，必须在类的 UrlAttribute 实例中封装该 URL。
