@KirkWoll , with all respect , is that really important ? I guess question is something else !! — Mehran, May 14 '13 at 16:19
@Mehran, it's important because I can think of no conceivable (legitimate) reason that a person would want to write a program that broke their user's internet. — Kirk Woll, May 14 '13 at 16:20

one way is using command prompt in your program :

if you use this command : rasdial /disconnect it will disconnect your current internet connection from internet

for executing this command in c# you can use this code :

            string command = "rasdial /disconnect";
            System.Diagnostics.ProcessStartInfo procStartInfo = new System.Diagnostics.ProcessStartInfo("cmd", "/c " + command);
            procStartInfo.RedirectStandardOutput = true;
            procStartInfo.UseShellExecute = false;
            procStartInfo.CreateNoWindow = true;
            System.Diagnostics.Process proc = new System.Diagnostics.Process();
            proc.StartInfo = procStartInfo;
            proc.Start();

another solution from Windows API : RasHangUp function

Internet connection is still there – May 14 '13 at 17:30
execute `rasdial` on cmd , what's the output ? – Mehran May 14 '13 at 17:33
and still connected ? so I guess you should go with the API that mentioned above ! I'm not sure but I'm afraid that the API will do the same job as this command does ! – Mehran May 14 '13 at 17:35
yz still connected,is there any other way with wininet? – May 14 '13 at 17:37
I'll look around , I if find any other solution , I'll let you know ;) – Mehran May 14 '13 at 17:38
