（转）贾君鹏你妈妈喊你回家吃饭-利用WCF的Duplex推送消息

原文地址：/article/4996332.html

有点标题党了，最近因工作需要，想利用WCF的Duplex服务向Winform程序推送消息，写了个示例，主要参考了artech的相关文章和其他一些利用WCF向SilverLight客户端推送消息的文章。
先看运行效果：在网页中发送消息【如图】，Winform端接收到消息

public partial class GetMessageForm : Form,ISendMessageServiceCallback
{
SendMessageServiceClient client;

public GetMessageForm()
{
InitializeComponent();
client = new SendMessageServiceClient(new System.ServiceModel.InstanceContext(this));
}

private void btnStartGet_Click(object sender, EventArgs e)
{
client.GetMessage();
}

private delegate void UpdateListBoxDelegate(string Message);
private void UpdateListBox(string message)
{
this.listbMessage.Items.Add(message);
listbMessage.SelectedIndex = listbMessage.Items.Count - 1;
}
#region ISendMessageServiceCallback 成员

public void ReceiveMessage(MessageEntity messageEntity)
{
if (true == listbMessage.InvokeRequired)
{
listbMessage.Invoke(new UpdateListBoxDelegate(UpdateListBox), messageEntity.Content);
}
else
{
UpdateListBox(messageEntity.Content);
}
}

#endregion
