1.查询当前网络状态：
using Microsoft.VisualBasic.Devices; //判断当前网络连接状态 Network nw=new Network(); if(nw.IsAvailable) lbmsg.Text="网络已连接"; else lbmsg.Text="网络已断开";
2.实时监控网络状态
using System.Net.NetworkInformation; // Constructor public MainPage() { InitializeComponent(); // Subscribe to the NetworkAvailabilityChanged event DeviceNetworkInformation.NetworkAvailabilityChanged += new EventHandler<NetworkNotificationEventArgs>(NetworkAvailabilityChanged); } void NetworkAvailabilityChanged(object sender, NetworkNotificationEventArgs e) { string msg=""; if(e.IsAvailable) { msg="网络已连接"; } else { msg="网络已断开"; } Dispatcher.BeginInvoke(() => { lbmsg.Text =msg; }); }
