c# - 如何在 windows Phone 7.1 中实现等待功能

Question

我想使用来自客户端的 IP 地址连接到服务器。要获取我正在使用下面的代码的服务器的 IP 地址，它可以正确检测服务器，但我想在HostEndPoint事件处理程序设置变量后执行一些其他功能，直到我需要等待我该如何实现它？.. 下面用于扫描的代码是正确的方法吗？如果没有怎么办？

谢谢

int startIp = 0;
int EndIp = 255;
int HostPort = 4678;
string = ipPrefix = "192.168.1.";
EndPoint HostEndPoint;

private void ScanHosts()
        {

           Socket clientSocket = new Socket(AddressFamily.InterNetwork,   SocketType.Stream, ProtocolType.Tcp);

        for (startIP = 0; startIP <= endIP; startIP++)
        {
            DnsEndPoint endPoint = new DnsEndPoint(ipPrefix + startIP.ToString(), HostPort);

            try
            {
                SocketAsyncEventArgs socketEventArgs = new SocketAsyncEventArgs();
                socketEventArgs.RemoteEndPoint = endPoint;
                socketEventArgs.UserToken = clientSocket;
                socketEventArgs.Completed += new EventHandler<SocketAsyncEventArgs>(socketEventArgs_Connected);


                clientSocket.ConnectAsync(socketEventArgs);


            }
            catch { }

        }

    }

private void socketEventArgs_Connected(object sender, SocketAsyncEventArgs e)
        {
            if (e.SocketError == SocketError.Success)
            {
                HostEndPoint = e.RemoteEndPoint;                
            }
        }

您可以使用 AutoResetEvent 。FE 我的用法：

 AutoResetEvent autoResetLoadDiscTitleAndPersonalDataById = new AutoResetEvent(false);
                                    DataService.LoadDiscTitleAndPersonalDataById(titleToSync.id_on_server, titleInfoXML =>
                                    {
                                        Title TitleInfo = new Title(titleInfoXML);
                                        TitleInfo.UpdateToDb();
                                        autoResetLoadDiscTitleAndPersonalDataById.Set();
                                    });
                                    autoResetLoadDiscTitleAndPersonalDataById.WaitOne();
