有人可以给我一个提示...我正在尝试使用 dotRAS .NET 控件，并且此代码internetConnected使用事件处理程序更改 (boolean) 的值...
但似乎该状态RasConnectionState.Disconnected不是由 dotRAS hangup() 触发的..
有任何想法吗？我做错了……还是我设法找到了一个错误？
public class USBModem
{
// private vars
private RasDialer dialer = new RasDialer();
private bool internetConnected = false;
/// <summary>
/// Default constructor for USBModem
/// </summary>
public USBModem()
{
// Add Events for dialer
dialer.StateChanged += new EventHandler<StateChangedEventArgs>(dialer_StateChanged);
}
void dialer_StateChanged(object sender, StateChangedEventArgs e)
{
// Handle state changes here
switch (e.State)
{
case RasConnectionState.Connected:
internetConnected = true;
Console.WriteLine(e.State.ToString());
break;
case RasConnectionState.Disconnected:
internetConnected = false;
Console.WriteLine(e.State.ToString());
break;
default:
Console.WriteLine("INFO -> Unhandled state: " + e.State.ToString());
break;
}
}
public void ConnectInternet(string connectionName)
{
// Dial
dialer.PhoneBookPath = RasPhoneBook.GetPhoneBookPath(RasPhoneBookType.AllUsers);
dialer.EntryName = connectionName;
dialer.DialAsync();
}
public void DisconnectInternet()
{
foreach (RasConnection connection in dialer.GetActiveConnections())
{
connection.HangUp();
}
}
}
