从LoveCherry的Blog的Remoting之六说起. (原文:http://www.cnblogs.com/lovecherry/archive/2005/05/23/160954.html)
一.这是一个客户端激活模式的例子

RemotingConfiguration.RegisterActivatedServiceType(typeof(RemoteObject.MyObject));
BinaryServerFormatterSinkProvider serverProvider = new BinaryServerFormatterSinkProvider();
BinaryClientFormatterSinkProvider clientProvider = new BinaryClientFormatterSinkProvider();
serverProvider.TypeFilterLevel = TypeFilterLevel.Full;
IDictionary props = new Hashtable();
props["port"]=8888;
TcpChannel channel = new TcpChannel(props,clientProvider,serverProvider);
ChannelServices.RegisterChannel(channel);
Console.ReadLine();
}
}
}

以上用了客户端激活模式: 有以下特性:
1、客户端激活的时间是在客户端请求的时候，而服务端激活远程对象的时间是在调用对象方法的时候
2、客户端激活可以调用自定义的构造方法，而不像服务端激活只能使用默认的构造方法
3、客户端激活模式一旦获得客户端的请求，将为每一个客户端都建立一个实例引用.服务器的 SingleCall 模式是每个请求有各自的实例引用, SingleTon 模式每个类只有一个实例引用.
4. 客户端激活是有状态的.服务器的 SingleTon 是有状态的,而 SingleCall 是没有状态的.
客户端激活用法特点如下:
1.服务器端用RemotingConfiguration.ApplicationName="RemoteObject.MyObject";来注册一个服务器Uri.
作用是,注册客户端激活方式中,要用一个 服务器的 Uri . 客户端用RemotingConfiguration.RegisterActivatedClientType(typeof(RemoteObject.MyObject),"tcp://localhost:8888/RemoteObject.MyObject");来远程注册对象类型.
2.注册知名类型,以便客户端在创建这些类型的时候,是从服务器端创建.
RemotingConfiguration.RegisterActivatedServiceType(typeof(RemoteObject.MyObject));
客户端有两种方式:一种是先注册再声明: 像这样:
RemotingConfiguration.RegisterActivatedClientType(typeof(RemoteObject.MyObject), "tcp://localhost:8888/RemoteServer");
app = new RemoteObject.MyObject();
还可以:
3.其中远程对象,要继承自 MarshalByRefObject

二.把程序改成 服务器端激活 的 SingleTon 模式.
[改SingleTon]1.服务器端代码:
static void Main(string[] args)
{
RemotingConfiguration.ApplicationName = "RemoteServer";
RemotingConfiguration.RegisterWellKnownServiceType(typeof(RemoteObject.MyObject),"MyObject",WellKnownObjectMode.Singleton);
RemotingConfiguration.RegisterWellKnownServiceType(typeof(RemoteObject.EventClass),"EventClass",WellKnownObjectMode.Singleton);
RemotingConfiguration.RegisterWellKnownServiceType(typeof(RemoteObject.MyObject.MyEventHandler),"MyEventHandler",WellKnownObjectMode.Singleton);
BinaryServerFormatterSinkProvider serverProvider = new BinaryServerFormatterSinkProvider();
BinaryClientFormatterSinkProvider clientProvider = new BinaryClientFormatterSinkProvider();
serverProvider.TypeFilterLevel = TypeFilterLevel.Full;
IDictionary props = new Hashtable();
props["port"] = 8888;
TcpChannel channel = new TcpChannel(props, clientProvider, serverProvider);
ChannelServices.RegisterChannel(channel);
Console.ReadLine();
}
{
RemotingConfiguration.ApplicationName = "RemoteServer";
RemotingConfiguration.RegisterWellKnownServiceType(typeof(RemoteObject.MyObject),"MyObject",WellKnownObjectMode.Singleton);
RemotingConfiguration.RegisterWellKnownServiceType(typeof(RemoteObject.EventClass),"EventClass",WellKnownObjectMode.Singleton);
RemotingConfiguration.RegisterWellKnownServiceType(typeof(RemoteObject.MyObject.MyEventHandler),"MyEventHandler",WellKnownObjectMode.Singleton);
BinaryServerFormatterSinkProvider serverProvider = new BinaryServerFormatterSinkProvider();

IDictionary props = new Hashtable();
props["port"] = 8888;
TcpChannel channel = new TcpChannel(props, clientProvider, serverProvider);
ChannelServices.RegisterChannel(channel);
Console.ReadLine();
}
[改SingleTon]2.客户端代码:

app.MyEvent += new RemoteObject.MyObject.MyEventHandler(ec.MyEvent);
md = new MyDelegate(app.ALongTimeMethod);
AsyncCallback ac = new AsyncCallback(MyClient.CallBack);
IPHostEntry ipHE = Dns.GetHostByName(Dns.GetHostName());

Console.ReadLine();
}
public static void CallBack(IAsyncResult Iar)
{
if (Iar.IsCompleted)
{
Console.WriteLine("结果是" + md.EndInvoke(Iar));
app.MyEvent -= new RemoteObject.MyObject.MyEventHandler(ec.MyEvent);
}
}
public static void Method()
{
Console.WriteLine("主线程方法开始");
System.Threading.Thread.Sleep(5000);
Console.WriteLine("主线程方法结束");
}
{
dt = DateTime.Now;
//RemotingConfiguration.RegisterWellKnownClientType(typeof(RemoteObject.MyObject), "tcp://localhost:8888/RemoteServer");

}
}
public static void Method()
{
Console.WriteLine("主线程方法开始");

Console.WriteLine("主线程方法结束");
}
运行结果,是 所有显示内容,都在服务器端显示.其中,客户端的Main函数也可以写成:
[改SingleTon]3.客户端的另一种写法(先用 RegisterWellKnownClientType 注册,再用 new 的方法远程声明.)
static void Main(string[] args)
{
dt = DateTime.Now;
RemotingConfiguration.RegisterWellKnownClientType(typeof(RemoteObject.MyObject), "tcp://localhost:8888/MyObject");
RemotingConfiguration.RegisterWellKnownClientType(typeof(RemoteObject.EventClass), "tcp://localhost:8888/EventClass");//这里不应该在远程注册这个对象,这里只是为了调试说明.

app = new RemoteObject.MyObject();
ec = new RemoteObject.EventClass();
//app = (RemoteObject.MyObject)Activator.GetObject(typeof(RemoteObject.MyObject), "tcp://localhost:8888/MyObject");
//ec = (RemoteObject.EventClass)Activator.GetObject(typeof(RemoteObject.EventClass), "tcp://localhost:8888/EventClass");
app.MyEvent += new RemoteObject.MyObject.MyEventHandler(ec.MyEvent);
md = new MyDelegate(app.ALongTimeMethod);
AsyncCallback ac = new AsyncCallback(MyClient.CallBack);
IPHostEntry ipHE = Dns.GetHostByName(Dns.GetHostName());
Random rnd = new Random(System.Environment.TickCount);
string ip = ipHE.AddressList[0].ToString() + "(" + rnd.Next(100000000).ToString() + ")";
app.tmp = ip;
IAsyncResult Iar = md.BeginInvoke(1, 2, 500, ip, ac, null);
Method();
Console.WriteLine("用了" + ((TimeSpan)(DateTime.Now - dt)).TotalSeconds + "秒");
ChannelServices.UnregisterChannel(channel);
Console.ReadLine();
}
{
dt = DateTime.Now;
RemotingConfiguration.RegisterWellKnownClientType(typeof(RemoteObject.MyObject), "tcp://localhost:8888/MyObject");
RemotingConfiguration.RegisterWellKnownClientType(typeof(RemoteObject.EventClass), "tcp://localhost:8888/EventClass");//这里不应该在远程注册这个对象,这里只是为了调试说明.
BinaryServerFormatterSinkProvider serverProvider = new BinaryServerFormatterSinkProvider();
BinaryClientFormatterSinkProvider clientProvider = new BinaryClientFormatterSinkProvider();
serverProvider.TypeFilterLevel = TypeFilterLevel.Full;
IDictionary props = new Hashtable();

TcpChannel channel = new TcpChannel(props, clientProvider, serverProvider);
ChannelServices.RegisterChannel(channel);
app = new RemoteObject.MyObject();

md = new MyDelegate(app.ALongTimeMethod);
AsyncCallback ac = new AsyncCallback(MyClient.CallBack);
IPHostEntry ipHE = Dns.GetHostByName(Dns.GetHostName());
Random rnd = new Random(System.Environment.TickCount);
string ip = ipHE.AddressList[0].ToString() + "(" + rnd.Next(100000000).ToString() + ")";
app.tmp = ip;
IAsyncResult Iar = md.BeginInvoke(1, 2, 500, ip, ac, null);

Console.WriteLine("用了" + ((TimeSpan)(DateTime.Now - dt)).TotalSeconds + "秒");
ChannelServices.UnregisterChannel(channel);
Console.ReadLine();
}
同样,结果都会显示在服务器端.这是因为: RemoteObject.EventClass 在[改SigleTon]中,注册成了服务器端的对象. 所以它就会再服务器端执行.[改SigleTon]2.中的
ec = (RemoteObject.EventClass)Activator.GetObject(typeof(RemoteObject.EventClass), "tcp://localhost:8888/EventClass");//这里应该直接用 new 方法.否则.会在服务器端输出信息.为了调试说明.
改为:
ec = new RemoteObject.EventClass;
即可.
或把 [改SigleTon]3. 中的
RemotingConfiguration.RegisterWellKnownClientType(typeof(RemoteObject.EventClass), "tcp://localhost:8888/EventClass");//这里不应该在远程注册这个对象,这里只是为了调试说明.
去掉即可.
但是.如果先后开两个客户端. 会看到. 第一个客户端会显示第二个客户端的内容.结果如下:
主线程方法开始
异步方法完成了10%
异步方法完成了20%
异步方法完成了30%
异步方法完成了40%
异步方法完成了10%
异步方法完成了20%
异步方法完成了30%
异步方法完成了40%
异步方法完成了50%
主线程方法结束
用了5.1273728秒
异步方法完成了60%
结果是3
异步方法完成了10%
异步方法完成了20%
异步方法完成了30%
异步方法完成了40%
异步方法完成了10%
异步方法完成了20%
异步方法完成了30%
异步方法完成了40%
异步方法完成了50%
主线程方法结束
用了5.1273728秒
异步方法完成了60%
结果是3
这充分说明了. SigleTon 在服务器端只有一个实例.是单件模式的. 客户端得到的,是最后一个客户所产生的进度.
二.改为服务器端激活的SigleCall模式.
把 [改SigleTon]1.服务器端代码中的 SingleTon 改为 SigleCall 即可.
运行结果 服务器端显示正确. 客户端没有显示进度.
客户端不注册EventClass .客户端也不会显示进度. 在客户端 注册 EventClass 如下:
RemotingConfiguration.RegisterWellKnownClientType(typeof(RemoteObject.EventClass), "tcp://localhost:8888/EventClass");
服务器端也不会显示客户端进度.
这足以说明: SigleCall 是没有状态的. 所以,客户端所创建的 RemoteObject.MyObject 是无法传递属性到服务器端的. 也不能绑定委托到客户端上.
原文为了在客户端上分别得到结果,所以用了 客户端激活模式.
