除了以硬编码的形式来注册对象,也可以以配置文件的方式来注册,以便增加灵活性

1.服务器端配置文件

其中以system.runtime.remoting 为配置节点

配置了信道和注册对象,看起来非常的容易理解

<configuration><system.runtime.remoting><application><channels><channel ref="http" port="1234" /></channels><service><wellknown mode="Singleton" type="Server.CustomerManager, Server" objectUri="CustomerManager.soap" /></service></application></system.runtime.remoting></configuration>

2.Server端代码

static void Main(string[] args){Console.WriteLine ("ServerStartup.Main(): Server started");String filename = "server.exe.config";RemotingConfiguration.Configure(filename);// the server will keep running until keypress.Console.ReadLine();}

3.客户端同样是采用配置文件

不过节点为client

<configuration><system.runtime.remoting><application><client><wellknown type="Server.CustomerManager, Client"  url="http://localhost:1234/CustomerManager.soap" /></client></application></system.runtime.remoting></configuration>

4.定义服务器端对象代理

需加上SoapType和SoapMethod来表示这个对象

[Serializable, SoapType(XmlNamespace=@"http://schemas.microsoft.com/clr/nsassem/Server/Server%2C%20Version%3D1.0.1584.30404%2C%20Culture%3Dneutral%2C%20PublicKeyToken%3Dnull", XmlTypeNamespace=@"http://schemas.microsoft.com/clr/nsassem/Server/Server%2C%20Version%3D1.0.1584.30404%2C%20Culture%3Dneutral%2C%20PublicKeyToken%3Dnull")]public class CustomerManager : System.MarshalByRefObject{[SoapMethod(SoapAction=@"http://schemas.microsoft.com/clr/nsassem/Server.CustomerManager/Server#GetCustomer")]public General.Customer GetCustomer(Int32 id){return((General.Customer) (Object) null);}}

5.客户端访问

static void Main(string[] args){String filename = "client.exe.config";RemotingConfiguration.Configure(filename);CustomerManager mgr = new CustomerManager();Console.WriteLine("Client.Main(): Reference to CustomerManager acquired");Customer cust = mgr.GetCustomer(4711);int age = cust.GetAge();Console.WriteLine("Client.Main(): Customer {0} {1} is {2} years old.",cust.FirstName,cust.LastName,age);Console.ReadLine();}    

6.以接口形式访问

6.1先读取客户端配置文件接口对象

class RemotingHelper{private static IDictionary _wellKnownTypes;public static Object CreateProxy(Type type){if (_wellKnownTypes == null) InitTypeCache();WellKnownClientTypeEntry entr = (WellKnownClientTypeEntry)_wellKnownTypes[type];if (entr == null){throw new RemotingException("Type not found!");}return Activator.GetObject(entr.ObjectType, entr.ObjectUrl);}public static void InitTypeCache(){Hashtable types = new Hashtable();foreach (WellKnownClientTypeEntry entr inRemotingConfiguration.GetRegisteredWellKnownClientTypes()){if (entr.ObjectType == null){throw new RemotingException("A configured type could not " +"be found. Please check spelling in your configuration file.");}types.Add(entr.ObjectType, entr);}_wellKnownTypes = types;}}

6.2客户端获取

static void Main(string[] args){String filename = AppDomain.CurrentDomain.SetupInformation.ConfigurationFile;RemotingConfiguration.Configure(filename);IRemoteCustomerManager mgr = (IRemoteCustomerManager) RemotingHelper.CreateProxy(typeof(IRemoteCustomerManager));Console.WriteLine("Client.Main(): Reference to rem.obj. acquired");Customer cust = mgr.GetCustomer(42);Console.WriteLine("Retrieved customer {0} {1}", cust.FirstName,cust.LastName);Console.ReadLine();}
