wcf双工通信聊天室（wpf+c#）-爱代码爱编程 (2024)

WCF部分

Service1.svc.cs源码

IService1.cs源码

Use类

WPF部分

MainWindow.xaml.cs源码

MainWindow.xaml源码

操作

不足

要用双工通信先配置文件在Web.config那里，怎么配置自行搜索。

关于WCF和WPF的服务引用可以看这篇文章WPF调WCF服务端

Service1.svc.cs源码

using GobangGameWcfService;using System;using System.Collections.Generic;using System.Linq;using System.Runtime.Serialization;using System.ServiceModel;using System.ServiceModel.Web;using System.Text;namespace WcfService_ChatService{ // 注意: 使用“重构”菜单上的“重命名”命令，可以同时更改代码、svc 和配置文件中的类名“Service1”。 // 注意: 为了启动 WCF 测试客户端以测试此服务，请在解决方案资源管理器中选择 Service1.svc 或 Service1.svc.cs，然后开始调试。 public class Service1 : IService1 { public Service1() { if (Users.userList == null) Users.userList = new List<User>(); } private IChatServiceCallback callback; public void Login(string username) { OperationContext context = OperationContext.Current; callback = context.GetCallbackChannel<IChatServiceCallback>(); User newUser = new User(username, callback); newUser.userName = username; foreach (var userone in Users.userList) { if(newUser.userName == userone.userName) { callback.ShowWrongLogin(userone.userName); return; } } Users.userList.Add(newUser); foreach (var usertwo in Users.userList) { usertwo.callback.ShowLogin(username, Users.userList.Count); } //callback.ShowUserList(Users.userList); } public void Logout(string userName) { User removeUser = null; foreach (User one in Users.userList) { if (one.userName == userName) { removeUser = one; break; } } if(removeUser == null) { callback.ShowWrongLogout(userName); return; } Users.userList.Remove(removeUser); foreach (var user in Users.userList) { user.callback.ShowLogout(userName, Users.userList.Count); } } public void sendInfo(string info , string userName) { foreach (var user in Users.userList) { user.callback.ShowSendInfo(info, userName); } } public class Users { public static List<User> userList; } /* public class User { public string userName; public DateTime loginTime; public User(string userName) { this.userName = userName; } } public class Users { public static List<User> userList; }*/ }}

IService1.cs源码

using System;using System.Collections.Generic;using System.Linq;using System.Runtime.Serialization;using System.ServiceModel;using System.ServiceModel.Web;using System.Text;using static WcfService_ChatService.Service1;namespace WcfService_ChatService{ [ServiceContract(CallbackContract = typeof(IChatServiceCallback))] //服务端 public interface IService1 { [OperationContract(IsOneWay = true)] void Login(string userName); [OperationContract(IsOneWay = true)] void sendInfo(string info,string userName); [OperationContract(IsOneWay = true)] void Logout(string userName); }/* [DataContract] public class User { [DataMember]public string userName { get; set; } public readonly IChatServiceCallback callback //[DataMember] public DateTime loginTime{ get; set; } } */ //客户端 public interface IChatServiceCallback { [OperationContract(IsOneWay = true)] void ShowLogin(string userName, int userCount); [OperationContract(IsOneWay = true)] void ShowSendInfo(string info , string infousername); [OperationContract(IsOneWay = true)] void ShowLogout(string userName, int userCount); [OperationContract(IsOneWay = true)] void ShowWrongLogin(string userName); [OperationContract(IsOneWay = true)] void ShowWrongLogout(string userName); //[OperationContract(IsOneWay = true)] //void ShowUserList(List<User> usersList); }}
