Mavzu: Kliyent tomondan holatni boshqarish Reja: c # da tarmoq aloqasi.(Tcp protokoli) Server qismining asoslari Windows 0, va 7-da Telnet-ni sozlash. Mijoz(Client) qismining asoslari

TcpClient client = server.AcceptTcpClient();
// Server parametrini o`rnatish
IPAddress localAddr = IPAddress.Parse("127.0.0.1");
int port = 8888;
TcpListener server = new TcpListener(localAddr, port);
// serverni ishga tushirish
server.Start();
// chekzis takrorlanish

// Cliyentga ulanish
TcpClient client = server.AcceptTcpClient();
NetworkStream stream = client.GetStream();
// ma’lumot almashish
try
{
if (stream.CanRead)
{
byte[] myReadBuffer = new byte[1024];
StringBuilder myCompleteMessage = new StringBuilder();
int numberOfBytesRead = 0;
do
{
numberOfBytesRead = stream.Read(myReadBuffer, 0, myReadBuffer.Length);
myCompleteMessage.AppendFormat("{0}", Encoding.UTF8.GetString(myReadBuffer, 0, numberOfBytesRead));
}
while (stream.DataAvailable);
Byte[] responseData = Encoding.UTF8.GetBytes("Muvafaqqiyatli amalga oshirildi!");
stream.Write(responseData, 0, responseData.Length);

E'tibor bering, mijoz tomonidan farqli o'laroq, server avval kiruvchi xabarni qabul qiladi va shundan keyingina javob yuboradi (harakatlarning teskari tartibi).
Shuni ham ta'kidlash kerakki, istisno holatida, server to'xtab qoladi va cheksiz sikl tugaydi, shunda juda muhim xatolik yuz berganda dastur "osilib qolmaydi".
Tarmoq va dastur bilan ishlash
Tarmoq orqali aloqa juda ko'p vaqt talab qilishi mumkin. O'z navbatida, mijozning serverga ulanishini kutish umuman doimiy davom etishi mumkin. Bularning barchasi dasturga kirish imkoni bo'lmasligiga olib kelishi mumkin (“Uzoq to`xtalishi").
Bunga yo'l qo'ymaslik uchun Tarmoq oqimida tarmoq bilan ishlash qat'iyan tavsiya etiladi.
3. Windows 10, 8 va 7-da Telnet-ni sozlash.
Windows 10,8 da 7 ta Telnet mijozi va server boshlang`ich bo'yicha o'chirib qo'yilgan. Siz ularni buyruq satri yoki boshqaruv paneli yordamida yoqishingiz mumkin.
Buyruq satridan foydalanib Telnet-ni ishga tushirish:
1. Buyruqlar satrini administrator sifatida ishga tushiring: qidiruv satrida Windows-ning istalgan versiyasidagi usullardan biri cmd => kiriting va taklif qilingan variant ustiga o'ng tugmasini bosing => administrator sifatida ishga tushiring;
2. Telnet mijozini yoqish uchun pkgmgr / iu kiriting: "TelnetClient" yoki dism / onlayn / Enable-Feature / FeatureName: TelnetClientand buyrug'i va Enter tugmasini bosing;
