  您可以使用WiFiDirectConnectionListener来实现此目标 . 当其他设备通过Wifi SoftAP连接到主机设备时，WiFiDirectConnectionListener将捕获连接请求 .

  private Dictionary<string,DeviceInformation> connectionDeviceList = new Dictionary<string, DeviceInformation>();

  WiFiDirectConnectionListener wifiAPListener = new WiFiDirectConnectionListener();
      wifiAPListener.ConnectionRequested += WifiAPListener_ConnectionRequested;

  private void WifiAPListener_ConnectionRequested(WiFiDirectConnectionListener sender, WiFiDirectConnectionRequestedEventArgs args)
      {
          try
          {
              var request = args.GetConnectionRequest();
              var devInfo = request.DeviceInformation;
  
              var wfdDevice = await WiFiDirectDevice.FromIdAsync(devInfo.Id);
              wfdDevice.ConnectionStatusChanged += WfdDevice_ConnectionStatusChanged;
  
              if (!connectionDeviceList.ContainsKey(devInfo.Id))
              {
                  connectionDeviceList.Add(devInfo.Id, devInfo);
              }
          }
          catch(Exception ex)
          {
              Debug.Write(ex.StackTrace);
          }           
      }
  
      private void WfdDevice_ConnectionStatusChanged(WiFiDirectDevice sender, object args)
      {
          try
          {
              if (sender.ConnectionStatus == WiFiDirectConnectionStatus.Disconnected)
              {
                  if (connectionDeviceList.ContainsKey(sender.DeviceId))
                  {
                      connectionDeviceList.Remove(sender.DeviceId);
                  }
              }
          }
          catch(Exception ex)
          {
              Debug.Write(ex.StackTrace);
          }
      }
  

  DeviceInformation的名称是您连接wifi热点的设备的MAC，您可以通过设置断点获取更多信息 . 当您断开连接时，WiFiDirectDevice将调用ConnectionStatusChanged事件 .
