If you give someone a program , you will frustrate them for a day; if you teach them how to program, you will frustrate them for a lifetime.IT 這段話的意思是，如果你交給某人一隻程式，你將折磨他一整天;如果你教會某人如何寫程式，你將折磨他一輩子。

用c#監控網絡狀態 - tuyile006

文章出處

1.查詢當前網絡狀態：

using  Microsoft.VisualBasic.Devices;

//判斷當前網絡連接狀態

Network nw=new Network();

if(nw.IsAvailable)

    lbmsg.Text="網絡已連接";

else

    lbmsg.Text="網絡已斷開";

2.實時監控網絡狀態

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="網絡已連接";

   }
   else
  {
    msg="網絡已斷開";
  }
  Dispatcher.BeginInvoke(() => {
  lbmsg.Text =msg; }); 
}
