Я разрабатываю приложение передачи файлов через среднего уровень жадной маршрутизацию, в котором файл отправляет жадные и жадные отправляет файл снова маршрутизатор но проблема некоторое время клиент получает полный файл и через некоторое время он получит какую-то часть файлаПоловина передачи файлов в C# через сокет?
Вот мой код идет сторона SERVER
IPAddress[] ipAddress = Dns.GetHostAddresses("127.0.0.1");
IPEndPoint ipEnd = new IPEndPoint(ipAddress[0], 5655);
Socket clientSock = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.IP);
string filePath = "";
fileDes = fileDes.Replace("\\", "/");
while (fileDes.IndexOf("/") > -1)
{
filePath += fileDes.Substring(0, fileDes.IndexOf("/") + 1);
fileDes = fileDes.Substring(fileDes.IndexOf("/") + 1);
}
byte[] fileNameByte = Encoding.ASCII.GetBytes(fileDes);
lblError.Text = "";
lblError.Text = "Buffering ...";
byte[] fileData = File.ReadAllBytes(filePath + fileDes);
byte[] clientData = new byte[4 + fileNameByte.Length + fileData.Length];
byte[] fileNameLen = BitConverter.GetBytes(fileNameByte.Length);
fileNameLen.CopyTo(clientData, 0);
fileNameByte.CopyTo(clientData, 4);
fileData.CopyTo(clientData, 4 + fileNameByte.Length);
lblError.Text = "";
lblError.Text = "Connection to server ...";
clientSock.Connect(ipEnd);
lblError.Text = "";
lblError.Text = "File sending...";
// System.Threading.Thread.Sleep(1000);
clientSock.Send(clientData);
label3.Text = clientData.Length.ToString();
lblError.Text = "";
lblError.Text = "Disconnecting...";
clientSock.Close();
lblError.Text = "";
lblError.Text = "File transferred.";
В клиенте
class DestCode
{
IPEndPoint ipEnd;
Socket sock;
public DestCode()
{
ipEnd = new IPEndPoint(IPAddress.Any, 5656);
sock = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.IP);
sock.Bind(ipEnd);
}
public static string receivedPath;
public static string curMsg = "Stopped";
public static int res;
public void StartServer()
{
try
{
curMsg = "Starting...";
sock.Listen(100);
curMsg = "Running and waiting to receive file.";
Socket clientSock = sock.Accept();
byte[] clientData = new byte[1024 * 5000];
int receivedBytesLen = clientSock.Receive(clientData);
curMsg = "Receiving data...";
int fileNameLen = BitConverter.ToInt32(clientData, 0);
string fileName = Encoding.ASCII.GetString(clientData, 4, fileNameLen);
BinaryWriter bWrite = new BinaryWriter(File.Open(receivedPath +"/"+ fileName, FileMode.Append)); ;
bWrite.Write(clientData,4 + fileNameLen, receivedBytesLen - 4 - fileNameLen);
res = receivedBytesLen;
if (receivedPath == "")
{
MessageBox.Show("No Path was selected to Save the File");
}
curMsg = "Saving file...";
bWrite.Close();
clientSock.Close();
curMsg = "File Received ...";
StartServer();
}
catch (Exception ex)
{
curMsg = "File Receving error.";
}
}
}
В жадного
class ReceiverCode
{
IPEndPoint ipEnd;
Socket sock;
public ReceiverCode()
{
ipEnd = new IPEndPoint(IPAddress.Any, 5655);
sock = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.IP);
sock.Bind(ipEnd);
}
public static string receivedPath;
public static string curMsg = "Stopped";
public static string Rout = "";
public static int rlength = 0;
public static string MsgStatus = "";
public static byte[] send;
public void StartServer()
{
try
{
curMsg = "Starting...";
sock.Listen(100);
curMsg = "Running and waiting to receive file.";
Socket clientSock = sock.Accept();
byte[] clientData = new byte[1024 * 5000];
int receivedBytesLen = clientSock.Receive(clientData);
System.Threading.Thread.Sleep(5000);
rlength = receivedBytesLen;
curMsg = "Receiving data...";
int receive = clientSock.Receive(clientData);
send = new byte[receivedBytesLen];
Array.Copy(clientData, send, receivedBytesLen);
Rout = "Start";
clientSock.Close();
curMsg = "Reeived & Saved file; Server Stopped.";
StartServer();
}
catch (Exception ex)
{
curMsg = "File Receving error.";
}
}
}
Пожалуйста, кто-нибудь помочь мне
