Question

我有一个客户端 - 服务器应用程序，它通过WCF进行相互通信。他们还使用Castle Windsor来解决依赖关系。

我的目标是完全避免必须显式注册服务器或客户端WCF端点。我使用以下代码

通过'约定'实现了服务器端

// registers all services which implement exactly 1 [ServiceContract]
_windsorContainer.Register(
AllTypes.FromThisAssembly().IncludeNonPublicTypes().Where(
    t => 1 == (from i in t.GetInterfaces() where i.IsDefined(typeof(ServiceContractAttribute), true) select i).Count())
    .Configure(c => c.LifeStyle.PerWcfSession()
    .ActAs(new DefaultServiceModel().AddEndpoints(
         WcfEndpoint.BoundTo(new NetTcpBinding())
             .At("net.tcp://" + LocalAddress.ToString() + ":7601/" + c.ServiceType.Name),
         WcfEndpoint.FromEndpoint(new UdpDiscoveryEndpoint())
            ))

    ).WithService.Select(
    (Type type, Type[] baseTypes) => from i in type.GetInterfaces() where i.IsDefined(typeof(ServiceContractAttribute), true) select i
    )
);

此代码将查找当前程序集中的所有类，并且任何实现服务契约接口（由ServiceContract属性标识）的类都将在地址“net.tcp：// localhost”中注册（使用UDP发现）： 7601 / [服务合同接口名称]”。

现在，我只想要方程式的客户端。

通常，要使用castle为WCF合同生成客户端代理，以下代码将起作用：

var model = new DefaultClientModel
{
    Endpoint = WcfEndpoint.ForContract<IServiceContract>().BoundTo(new NetTcpBinding()).Discover(typeof(IServiceContract))
};

container.Register(
    Component.For<ChannelReconnectPolicy>(),
    Castle.Facilities.WcfIntegration.WcfClient.ForChannels(model),
);

我想要的是，Castle为给定程序集中的所有“服务契约”接口执行此类注册 - 但是AllTypes帮助程序似乎只返回类，而不是接口（我猜它是'AllClasses '，而不是'AllTypes'！）... Can Castle可以做到这一点，语法是什么？克日什托夫？（帮助！）

谢谢！

对这样一个迟到的回复道歉 - 开发人员的生活从来都不是一个安静的人！

我挖出了代码，并没有像我希望的那样“简洁”，也许有人可以将这样的东西整合到Castle中......但是这里有......

// these are all the namespaces that will be scanned for WCF service contracts
string[] remoteServiceNamespaces 
    = new string[] { "MyContracts.Services", "Interlinq" };

// everything from here on is in the Castle DLLs (all the types)
List<IRegistration> clientContractRegistrations = new List<IRegistration>();
foreach (
    var interfaceContract in
    (from s in remoteServiceNamespaces
    select (from i in Assembly.LoadWithPartialName(s).GetTypes()
        where i.IsInterface
        && 
        i.IsDefined(typeof(ServiceContractAttribute), false)
        select i)).SelectMany( x => x )
    )
{
    ServiceContractAttribute attr 
        = Attribute.GetCustomAttribute(
                    interfaceContract, 
                    typeof(ServiceContractAttribute)) 
                    as ServiceContractAttribute;
    if (null != attr)
    {
    WcfClientModelBase model = null;

    // here we handle the case of the service being duplex...
    if (null != attr.CallbackContract)
    {
        model = new DuplexClientModel
        {
        // All the automatically registered services will use NetTcp, 
        // and will discover their addresses (you could use binding 
        // inference aswell if you liked)
        // here I have a method called 'CreateNetTcpBinding' which 
        // creates my custom binding that ALL my services use.
        Endpoint = 
                 WcfEndpoint.ForContract(interfaceContract)
                 .BoundTo(CreateNetTcpBinding())
                 .Discover(interfaceContract)
                 .PreferEndpoint(list => list[0])
        }.Callback(_windsor.Resolve(attr.CallbackContract));
    }
    else
    {
        model = new DefaultClientModel
        {
        Endpoint = WcfEndpoint.ForContract(interfaceContract)
                    .BoundTo(new NetTcpBinding())
                    .Discover(interfaceContract)
                    .PreferEndpoint(list => list[0])
        };
    }
    clientContractRegistrations.Add(WcfClient.ForChannels(model));
    }
}

// now that we've built our registration list, let's actually register 
// them all with Windsor
_windsor.Register(
    clientContractRegistrations.ToArray()
    );
