实现双工通讯主要分三步。
- 通信接口的定义;
- 被调用接口的实现
- 双工通道的建立
请先引用DLL(CSDN的代码编辑器真尼玛蛋疼)
整个解决方案的结构
1、通信接口的定义;
服务端调用客户端接口IServerCallClient
- /// <summary>
- /// 服务器调用客户端接口
- /// </summary>
- public interface IServerCallClient
- {
- /// <summary>
- /// 服务器读取客户端的IP
- /// </summary>
- /// <returns></returns>
- [OperationContract]
- IPEndPoint ServerRequestCLientIP();
- /// <summary>
- /// 服务器发送消息给客户端
- /// </summary>
- /// <param name="text"></param>
- [OperationContract]
- void ServerSayMSG(string text);
- }
/// <summary> /// 服务器调用客户端接口 /// </summary> public interface IServerCallClient { /// <summary> /// 服务器读取客户端的IP /// </summary> /// <returns></returns> [OperationContract] IPEndPoint ServerRequestCLientIP(); /// <summary> /// 服务器发送消息给客户端 /// </summary> /// <param name="text"></param> [OperationContract] void ServerSayMSG(string text); }
客户端调用服务端接口IClientCallServer
- <span style="font-weight: normal;"> [ServiceContract(CallbackContract =typeof(IServerCallClient))]//指定回调的接口
- public interface IClientCallServer
- {
- /// <summary>
- /// 客户端发送消息给服务器
- /// </summary>
- /// <param name="text"></param>
- [OperationContract]//指定操作约束,不添加该接口方法不可使用
- void ClientSayToServer(string text);
- /// <summary>
- /// 客户端读取服务端时间
- /// </summary>
- /// <returns></returns>
- [OperationContract]
- DateTime ClientRequestTime();
- }</span>
<span style="font-weight: normal;"> [ServiceContract(CallbackContract =typeof(IServerCallClient))]//指定回调的接口 public interface IClientCallServer { /// <summary> /// 客户端发送消息给服务器 /// </summary> /// <param name="text"></param> [OperationContract]//指定操作约束,不添加该接口方法不可使用 void ClientSayToServer(string text); /// <summary> /// 客户端读取服务端时间 /// </summary> /// <returns></returns> [OperationContract] DateTime ClientRequestTime(); }</span>
上面的两个接口是单独的一个项目。
双方谈好了就好互相实现对方的方法。
2、被调用接口的实现
客户端实现服务端接口的类:
- class ServerCallClient :IServerCallClient
- {
- public IPEndPoint ServerRequestCLientIP()
- {
- var ip =new IPEndPoint(IPAddress.Any,10086);
- return ip;
- }
- public void ServerSayMSG(string text)
- {
- File.AppendAllText("收到的数据", text);
- }
- }
class ServerCallClient :IServerCallClient { public IPEndPoint ServerRequestCLientIP() { var ip =new IPEndPoint(IPAddress.Any,10086); return ip; } public void ServerSayMSG(string text) { File.AppendAllText("收到的数据", text); } }
服务端实现客户端接口的类
- /// <summary>
- /// 客户回调服务器类
- /// </summary>
- [ServiceBehavior(InstanceContextMode =InstanceContextMode.Single)]//通道只建立一个除非断开才新建(SessionID是同一个)
- public class ClientCallServer : IClientCallServer, IDisposable
- {
- public static List<IServerCallClient> ServerCallClientList { get; set; }=new List<IServerCallClient>();
- /// <summary>
- /// 返回服务器时间
- /// </summary>
- /// <returns></returns>
- public DateTime ClientRequestTime()
- {
- return DateTime.Now;
- }
- /// <summary>
- /// 客户端列表
- /// </summary>
- /// <summary>
- /// 服务端向客户端发数据
- /// </summary>
- /// <param name="text"></param>
- public void ClientSayToServer(string text)
- {
- var info = OperationContext.Current;
- File.AppendAllText("receive.txt",info.SessionId+text);//收到的数据存在文件
- }
- public void Dispose()
- {
- ServerCallClientList.Clear();
- }
- #endregion
- }
/// <summary> /// 客户回调服务器类 /// </summary> [ServiceBehavior(InstanceContextMode =InstanceContextMode.Single)]//通道只建立一个除非断开才新建(SessionID是同一个) public class ClientCallServer : IClientCallServer, IDisposable { public static List<IServerCallClient> ServerCallClientList { get; set; }=new List<IServerCallClient>(); /// <summary> /// 返回服务器时间 /// </summary> /// <returns></returns> public DateTime ClientRequestTime() { return DateTime.Now; } /// <summary> /// 客户端列表 /// </summary> /// <summary> /// 服务端向客户端发数据 /// </summary> /// <param name="text"></param> public void ClientSayToServer(string text) { var info = OperationContext.Current; File.AppendAllText("receive.txt",info.SessionId+text);//收到的数据存在文件 } public void Dispose() { ServerCallClientList.Clear(); } #endregion }
3、双工通道的建立
服务端通道的建立- ServiceHost serviceHost = new ServiceHost(typeof(ClientCallServer));//<span style="font-family: Arial, Helvetica, sans-serif;">指定回调的类</span>
- serviceHost.AddServiceEndpoint(typeof(IClientCallServer),new WSDualHttpBinding(), "http://localhost:12345");//指定客户端的接口,通讯格式,服务器的地址
- serviceHost.BeginOpen(callback=>
- {
- serviceHost.EndOpen(callback);
- textBox1.Invoke(new Action(delegate {//不解释也能看得懂吧
- textBox1.AppendText("服务开启" + Environment.NewLine);
- }));
- },null);
ServiceHost serviceHost = new ServiceHost(typeof(ClientCallServer));//<span style="font-family: Arial, Helvetica, sans-serif;">指定回调的类</span> serviceHost.AddServiceEndpoint(typeof(IClientCallServer),new WSDualHttpBinding(), "http://localhost:12345");//指定客户端的接口,通讯格式,服务器的地址 serviceHost.BeginOpen(callback=> { serviceHost.EndOpen(callback); textBox1.Invoke(new Action(delegate {//不解释也能看得懂吧 textBox1.AppendText("服务开启" + Environment.NewLine); })); },null);客户端通道的建立
- var rand = new Random();
- InstanceContext context = new InstanceContext(new ServerCallClient());//指定回调的类
- WSDualHttpBinding binding = new WSDualHttpBinding() { ClientBaseAddress = new Uri($"http://localhost:{rand.Next(10000, 20000)}") };//指定客户端地址;
- using (DuplexChannelFactory proxy = new DuplexChannelFactory(context, binding))//创建通道管理器
- {
- IClientCallServer client = proxy.CreateChannel(new EndpointAddress("http://localhost:12345"));// 创建用于将消息发送到特定终结点地址的服务的通道client.ClientRequestTime();
- client.ClientSayToServer("尼玛");
- }
