使用 System.ServiceModel.Routing.RoutingService 与 mex 进行 WCF 4.0 路由答案

【问题标题】：WCF 4.0 routing with mex using System.ServiceModel.Routing.RoutingService使用 System.ServiceModel.Routing.RoutingService 与 mex 进行 WCF 4.0 路由
【发布时间】：2011-07-10 01:09:44
【问题描述】：

我在以下地点为 MEX 工作：

net.tcp://remotehost:4508

什么是最短的 C#/F# 代码（很难理解 XML 配置文件 ^_^"）我可以写什么来为它创建一个路由器？：

net.tcp://localhost:4508

MEX 也应该正确路由，以便客户端可以使用路由器

svcutil net.tcp://localhost:4508

发现服务方法。

这是我对我的问题的回答，它完全符合我的要求 - 没有任何 XML 沙拉，不到 50 行 F#：

namespace CORSIS

module Application =

    open System

    open System.ServiceModel
    open System.ServiceModel.Routing
    open System.ServiceModel.Dispatcher
    open System.ServiceModel.Description


    let createSimpleRouter createBinding (routerAddress : string) serviceAddress = 

        let routerType = typeof<IRequestReplyRouter>
        let routerContract = ContractDescription.GetContract(routerType)
        let endpoint address = new ServiceEndpoint(routerContract, createBinding(), new EndpointAddress(address))

        let serviceEndpoints = [| endpoint serviceAddress |]
        let configuration = new RoutingConfiguration()
        configuration.FilterTable.Add(new MatchAllMessageFilter(), serviceEndpoints)

        let host = new ServiceHost(typeof<RoutingService>)
        ignore <| host.AddServiceEndpoint(routerType, createBinding(), routerAddress)
        host.Description.Behaviors.Add(new RoutingBehavior(configuration))
        host        

    [<EntryPoint>]
    let main(args) =

        let (routerAddress, serviceAddress) =
            match args with
            | [| ra; sa |] -> (ra, sa)
            | _ -> ("net.tcp://localhost:4508/", "net.tcp://remotehost:4508/")

        let netTcp() = new NetTcpBinding(SecurityMode.None)
        let mexTcp() = MetadataExchangeBindings.CreateMexTcpBinding()

        let tcpRouter = createSimpleRouter netTcp  routerAddress           serviceAddress
        let mexRouter = createSimpleRouter mexTcp (routerAddress + "mex") (serviceAddress + "mex")

        tcpRouter.Open()
        mexRouter.Open()

        Console.WriteLine("routing ...\n{0} <-> R:{1}", serviceAddress, routerAddress)

        ignore <| Console.ReadKey true

        0

这个很好，有C#版本吗？

【解决方案2】：

这应该是上面的代码 F# 转换为 C# 我真的不知道 F# 语言，所以它不能作为 F# 代码工作。但是我对其进行了测试，它成功地路由了元数据。

using System;
using System.ServiceModel;
using System.ServiceModel.Channels;
using System.ServiceModel.Routing;
using System.ServiceModel.Dispatcher;
using System.ServiceModel.Description;

namespace FSharpRouterInCSharp
{
    class Program
    {
        static ServiceHost createSimpleRouter (Binding createBinding, string routerAddress, string serviceAddress)
        {
            var routerType = typeof (IRequestReplyRouter);
            var routerContract = ContractDescription.GetContract(routerType);

            //var endpoint = new ServiceEndpoint(routerContract, createBinding, new EndpointAddress(address));

            var serviceEndpoints = new ServiceEndpoint[] { new ServiceEndpoint(routerContract, createBinding, new EndpointAddress(serviceAddress))};
            var configuration = new RoutingConfiguration();
            configuration.FilterTable.Add(new MatchAllMessageFilter(), serviceEndpoints);

            var host = new ServiceHost(typeof (RoutingService));
            host.AddServiceEndpoint(routerType, createBinding, routerAddress);
            host.Description.Behaviors.Add(new RoutingBehavior(configuration));
            return host;
        }

        static void Main(string[] args)
        {
            string routerAddress = "net.tcp://localhost:4508/";
            string serviceAddress = "net.tcp://remotehost:4508/";

            var netTcp = new NetTcpBinding(SecurityMode.None);
            var mextTcp = MetadataExchangeBindings.CreateMexTcpBinding();

            var tcpRouter = createSimpleRouter(netTcp, routerAddress, serviceAddress);
            var mexRouter = createSimpleRouter(mextTcp,routerAddress+"mex",serviceAddress+"mex");

            tcpRouter.Open();
            mexRouter.Open();

            Console.WriteLine("routing ...\n{0} <-> R:{1}", serviceAddress, routerAddress);
            Console.ReadKey();
        }
    }
}

抱歉，我不是在寻找有关讨论旧版本 WCF 或包括 XML 配置文件的文章的参考资料。
