Silverlight 客户端本地消息通讯

发送端
public partial class LM_Sender : UserControl { //定¨义?本?地?消?息¢发¢送í对?象ó,?这a个?最?关?键ü,?接ó收?方?和í发¢送í方?的?实μ例y名?必?须?一?样ù才?行D,?好?比èMQ的?通¨道à一?样ù private LocalMessageSender msgSender = new LocalMessageSender("terryfeng"); public LM_Sender() { InitializeComponent(); this.Loaded += new RoutedEventHandler(LM_Sender_Loaded); } void LM_Sender_Loaded(object sender, RoutedEventArgs e) { //提á前°加ó载?,?创′建¨消?息¢发¢送í完ê成é的?事?件t处|理í msgSender.SendCompleted += new EventHandler<SendCompletedEventArgs>(msgSender_SendCompleted); } private void btnSent_Click(object sender, RoutedEventArgs e) { //发¢送í消?息¢ msgSender.SendAsync(tbInput.Text); } void msgSender_SendCompleted(object sender, SendCompletedEventArgs e) { //显?示?回?复′的?消?息¢ MessageBox.Show(e.Response); } }
接收端
public partial class LM_Rec : UserControl { public LM_Rec() { InitializeComponent(); this.Loaded += new RoutedEventHandler(LM_Rec_Loaded); } void LM_Rec_Loaded(object sender, RoutedEventArgs e) { //创′建¨接ó收?消?息¢对?象ó LocalMessageReceiver msgRec = new LocalMessageReceiver("terryfeng"); //创′建¨接ó收?消?息¢的?事?件t处|理í msgRec.MessageReceived += new EventHandler<MessageReceivedEventArgs>(msgRec_MessageReceived); //开a始?侦ì听y msgRec.Listen(); } void msgRec_MessageReceived(object sender, MessageReceivedEventArgs e) { //显?示?收?到?的?消?息¢ tbkRec.Text = e.Message; //反′馈?消?息¢给?发¢送í者? e.Response = "我ò收?到?消?息¢了?,?谢?谢?!?"; } }
