C#.NET获取拨号连接的宽带连接方法

 class SinASDL { //ASDL在注册表中的存放位置，这个是针对WinXP的， //不知道Win7是否是这个，待验证 private static String _adlskeys = @"RemoteAccess\Profile"; public static String adlskeys { get { return _adlskeys; } } /// 
 /// 获取本机的拨号名称，也就是本机上所有的拨号 /// 
 ///  public static String[] GetASDLNames() { RegistryKey RegKey = Registry.CurrentUser.OpenSubKey(adlskeys); if (RegKey != null) return RegKey.GetSubKeyNames(); else return null; } private String _asdlname = null; private ProcessWindowStyle _windowstyle = ProcessWindowStyle.Hidden; /// 
 /// 实例化一个ASDL连接 /// 
 /// ASDL名称，如“宽带连接” /// 用户名 /// 密码 /// 窗口显示方式，默认为因此拨号过程 public SinASDL(String asdlname, String username = null, String password = null, ProcessWindowStyle windowstyle = ProcessWindowStyle.Hidden) { this.ASDLName = asdlname; this.Username = username; this.Password = password; this.WindowStyle = windowstyle; } /// 
 /// 拨号名称 /// 
 public String ASDLName { get { return this._asdlname; } set { this._asdlname = value; } } /// 
 /// 拨号进程的窗口方式 /// 
 public ProcessWindowStyle WindowStyle { get { return this._windowstyle; } set { this._windowstyle = value; } } private String _username = null;  //用户名 private String _password = null;  //密码 /// 
 /// 用户名 /// 
 public String Username { get { return this._username; } set { this._username = value; } } /// 
 /// 密码 /// 
 public String Password { get { return this._password; } set { this._password = value; } } /// 
 /// 开始拨号 /// 
 /// 返回拨号进程的返回值 public int Connect() { Process pro = new Process(); pro.StartInfo.FileName = "rasdial.exe"; pro.StartInfo.Arguments = this.ASDLName + " " + this.Username + " " + this.Password; pro.StartInfo.WindowStyle = this.WindowStyle; pro.Start(); pro.WaitForExit(); return pro.ExitCode; } ///

 //SinASDL asdl = new SinASDL("宽带连接", "08793312221", "123456"); //宽带连接 //使用枚举到的第一个进行拨号 SinASDL asdl = new SinASDL(SinASDL.GetASDLNames()[0], "08793312221", "123456", System.Diagnostics.ProcessWindowStyle.Normal); if (asdl.Connect() == 0) { MessageBox.Show("Success"); } else { MessageBox.Show("Fail"); }
