POWpf Server/client logon. Problems with events
text
Body
copied!<p>I’m pretty new to programming, so bear with me if my question isn’t specific enough. Right now I’m trying to make a simple Client Logon to my server. So the server App knows which users are connected. When a client connects I want an event to fire on the server that update the userlist. But it doesn’t and I can’t figure out why. Hope you can help.</p> <p>In the codes I have removed how the users should be displayed in the serverApp. Right now I just need the event to work. </p> <p><strong>In my Service Library:</strong></p> <p>INetworkService contract:</p> <pre><code>using System; using System.Collections.Generic; using System.Linq; using System.Runtime.Serialization; using System.ServiceModel; using System.Text; namespace NetworkLib { [ServiceContract] public interface INetworkService { [OperationContract] void Logon(UserInfo userInfo); [OperationContract] void Logout(); } } </code></pre> <p>NetworkService Class:</p> <pre><code>using System; using System.Collections.Generic; using System.Linq; using System.Runtime.Serialization; using System.ServiceModel; using System.Text; namespace NetworkLib { public class NetworkService : INetworkService { public event EventHandler UserListChanged; public void Logon(UserInfo userInfo) { OnUserListChanged(); } public void Logout() { OnUserListChanged(); } private void OnUserListChanged() { var handler = UserListChanged; if (handler != null) { handler(this, EventArgs.Empty); } } } } </code></pre> <p>UserInfo Class:</p> <pre><code>using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Runtime.Serialization; namespace NetworkLib { [DataContract] public class UserInfo { [DataMember] public string Name; } } </code></pre> <p><strong>In my ServerApp (WPF):</strong> </p> <pre><code>using System.ServiceModel; using NetworkLib; namespace ServerApp { public partial class MainWindow : Window { NetworkService networkService; public MainWindow() { InitializeComponent(); ServiceHost host = new ServiceHost(typeof(NetworkService)); host.Open(); networkService = new NetworkService(); networkService.UserListChanged += networkService_UserListChanged; } private void networkService_UserListChanged(object sender, EventArgs e) { MessageBox.Show("It Works!"); } } } </code></pre> <p><strong>In my ClientApp (WPF): (Have made a Service Reference to the Server)</strong></p> <pre><code>namespace ClientApp { public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); } private void button1_Click(object sender, RoutedEventArgs e) { ServiceReference.NetworkServiceClient proxy = new ServiceReference.NetworkServiceClient(); ServiceReference.UserInfo userInfo = new ServiceReference.UserInfo(); userInfo.Name = "Test"; proxy.Logon(userInfo); } } } </code></pre>
