ActivatedServiceTypeEntry 类
将在服务端注册的对象类型的值保存为可以应客户端请求激活的类型。
**命名空间:**System.Runtime.Remoting
**程序集:**mscorlib（在 mscorlib.dll 中）
语法
声明
<ComVisibleAttribute(True)> _
Public Class ActivatedServiceTypeEntry
Inherits TypeEntry
用法
Dim instance As ActivatedServiceTypeEntry
[ComVisibleAttribute(true)]
public class ActivatedServiceTypeEntry : TypeEntry
[ComVisibleAttribute(true)]
public ref class ActivatedServiceTypeEntry : public TypeEntry
/** @attribute ComVisibleAttribute(true) */
public class ActivatedServiceTypeEntry extends TypeEntry
ComVisibleAttribute(true)
public class ActivatedServiceTypeEntry extends TypeEntry
备注
当前类由 RemotingConfiguration.RegisterActivatedServiceType 方法使用，而该方法是 RemotingConfiguration.RegisterActivatedClientType 方法的服务器端副本。RegisterActivatedServiceType 方法在服务器上用来允许客户端远程激活指定的对象类型。
若要在服务器上创建客户端激活的对象，则必须知道其 Type，而且必须使用 RegisterActivatedServiceType 方法在服务器端注册该对象。若要获取新的客户端激活对象的代理，则客户端必须首先通过 ChannelServices 注册信道，然后通过调用 new 或 Activator.CreateInstance 来激活该对象。
若要激活具有 new 关键字的客户端激活对象类型，必须首先使用 RegisterActivatedClientType 方法在客户端注册该对象类型。通过调用 RegisterActivatedClientType 可为远程处理基础结构提供远程应用程序的位置，new 关键字试图在该处进行创建。另一方面，如果使用 CreateInstance 方法来创建客户端激活的对象的新实例，则必须提供远程应用程序的 URL 作为参数，因此，没有必要预先在客户端注册。若要为 CreateInstance 方法提供要在其上创建该对象的服务器的 URL，必须将该 URL 封装到 UrlAttribute 类的实例中。
有关客户端激活对象和远程对象激活的详细说明，请参阅 远程对象的激活。
