这篇文章主要给大家介绍了关于WCF如何绑定netTcpBinding寄宿到控制台应用程序的相关资料,文中通过示例代码介绍的非常详细,对大家学习或者使用WCF具有一定的参考学习价值,需要的朋友们下面来一起学习学习吧
契约
新建一个WCF服务类库项目,在其中添加两个WCF服务:GameService,PlayerService
代码如下:
[ServiceContract] public interface IGameService { [OperationContract] Task DoWork(string arg); }
public class GameService : IGameService { public async Task DoWork(string arg) { return await Task.FromResult($"Hello {arg}, I am the GameService."); } }
[ServiceContract] public interface IPlayerService { [OperationContract] Task DoWork(string arg); }
public class PlayerService : IPlayerService { public async Task DoWork(string arg) { return await Task.FromResult($"Hello {arg}, I am the PlayerService."); } }
服务端
新建一个控制台应用程序,添加一个类 ServiceHostManager
public interface IServiceHostManager : IDisposable { void Start(); void Stop(); } public class ServiceHostManager : IServiceHostManager where TService : class { ServiceHost _host; public ServiceHostManager() { _host = new ServiceHost(typeof(TService)); _host.Opened += (s, a) => { Console.WriteLine("WCF监听已启动!{0}", _host.Description.Endpoints[0].Address); }; _host.Closed += (s, a) => { Console.WriteLine("WCF服务已终止!{0}", _host.Description.Endpoints[0].Name); }; } public void Start() { Console.WriteLine("正在开启WCF服务...{0}", _host.Description.Endpoints[0].Name); _host.Open(); } public void Stop() { if (_host != null && _host.State == CommunicationState.Opened) { Console.WriteLine("正在关闭WCF服务...{0}", _host.Description.Endpoints[0].Name); _host.Close(); } } public void Dispose() { Stop(); } public static Task StartNew(CancellationTokenSource cancelTokenSource) { var theTask = Task.Factory.StartNew(() => { IServiceHostManager shs = null; try { shs = new ServiceHostManager(); shs.Start(); while (true) { if (cancelTokenSource.IsCancellationRequested && shs != null) { shs.Stop(); break; } } } catch (Exception ex) { Console.WriteLine(ex); if (shs != null) shs.Stop(); } }, cancelTokenSource.Token); return theTask; } }
在Main方法中启动WCF主机
class Program {<div style="color:transparent">来源gaodai.ma#com搞#代!码网</div> static Program() { Console.WriteLine("初始化..."); Console.WriteLine("服务运行期间,请不要关闭窗口。"); Console.WriteLine(); } static void Main(string[] args) { Console.Title = "WCF主机 x64.(按 [Esc] 键停止服务)"; var cancelTokenSource = new CancellationTokenSource(); ServiceHostManager.StartNew(cancelTokenSource); ServiceHostManager.StartNew(cancelTokenSource); while (true) { if (Console.ReadKey().Key == ConsoleKey.Escape) { Console.WriteLine(); cancelTokenSource.Cancel(); break; } } Console.ReadLine(); } }
服务端配置
在控制台应用程序的App.config中配置system.serviceModel
未避免元数据泄露,部署时将HttpGetEnable设为False
运行控制台应用程序
按[ESC]键终止服务
客户端测试
服务端运行后,用wcftestclient工具测试,服务地址即behavior中配置的元数据GET地址

http://localhost:8081/Wettery/PlayerService/MetaData
