Доброго времени суток!
Имеется следующий код мультипоточного сервера и клиента.
Сервер:
Код:
namespace Server_Test
{
class Server
{
static void Main(string[] args)
{
Server serv = new Server();
}
private TcpListener listener { get; set; }
private NetworkStream stream { get; set; }
public Server()
{
listener = new TcpListener(IPAddress.Parse("192.168.1.2"), 5052);
listener.Start();
new Thread(ListenForClients).Start();
}
private void ListenForClients()
{
while (true)
{
TcpClient client = this.listener.AcceptTcpClient();
new Thread(HandleClient).Start(client);
}
}
private void HandleClient(object tcpClient)
{
TcpClient client = (TcpClient)tcpClient;
while (client.Connected)
{
Recieve(client);
}
}
private void Recieve(TcpClient client)
{
byte[] buffer = new byte[client.ReceiveBufferSize];
Array.Clear(buffer, 0, buffer.Length);
try
{
stream = client.GetStream();
stream.Flush();
int bytesRead = stream.Read(buffer, 0, 12);
if (bytesRead == 0) return;
ushort id = BitConverter.ToUInt16(buffer, 0);
long len = BitConverter.ToInt64(buffer, 2);
ushort nameLen = BitConverter.ToUInt16(buffer, 10);
stream.Read(buffer, 0, nameLen);
string fileName = Encoding.UTF8.GetString(buffer, 0, nameLen);
if (id == 1)
{
using (BinaryWriter writer = new BinaryWriter(new FileStream(fileName, FileMode.Create)))
{
int recieved = 0;
while (recieved < len)
{
bytesRead = stream.Read(buffer, 0, client.ReceiveBufferSize);
recieved += bytesRead;
writer.Write(buffer, 0, bytesRead);
Console.WriteLine("{0} bytes recieved.", recieved);
}
}
Console.WriteLine("File length: {0}", len);
Console.WriteLine("File Name: {0}", fileName);
Console.WriteLine("Recieved!");
stream.Flush();
Array.Clear(buffer, 0, buffer.Length);
}
else
{
Console.WriteLine(fileName);
}
}
catch (Exception ex)
{
stream.Close();
client.Close();
Console.WriteLine(ex);
}
finally
{
stream.Flush();
Array.Clear(buffer, 0, buffer.Length);
}
}
}
}
Клиент:
Код:
namespace ClientTest
{
internal class Program
{
private static TcpClient client;
private static NetworkStream stream;
private static void Main(string[] args)
{
string temp;
client = new TcpClient("192.168.1.2",5052);
//stream = client.GetStream();
Console.WriteLine(client.SendBufferSize);
/*while ((temp = Console.ReadLine()) != "exit")
{
Send(temp);
}*/
Thread one=new Thread(()=> SendFile(new FileInfo(@"1.doc")));
one.Start();
Thread two=new Thread(()=> SendFile(new FileInfo(@"2.docx")));
two.Start();
// Console.ReadKey(true);
}
public static void SendFile(FileInfo file)
{
stream = client.GetStream();
stream.Flush();
byte[] id = BitConverter.GetBytes((ushort)1);
byte[] size = BitConverter.GetBytes(file.Length);
byte[] fileName = Encoding.UTF8.GetBytes(file.Name);
byte[] fileNameLength = BitConverter.GetBytes((ushort)fileName.Length);
byte[] fileInfo = new byte[12 + fileName.Length];
id.CopyTo(fileInfo, 0);
size.CopyTo(fileInfo, 2);
fileNameLength.CopyTo(fileInfo, 10);
fileName.CopyTo(fileInfo, 12);
stream.Write(fileInfo, 0, fileInfo.Length); //Размер файла, имя
byte[] buffer = new byte[1024 * 32];
int count;
long sended = 0;
using (FileStream fileStream = new FileStream(file.FullName, FileMode.Open))
while ((count = fileStream.Read(buffer, 0, buffer.Length)) > 0)
{
stream.Write(buffer, 0, count);
sended += count;
Console.WriteLine("{0} bytes sended.", sended);
}
stream.Flush();
Array.Clear(buffer, 0, buffer.Length);
}
}
Проблема состоит в следующем:
При попытке передачи с клиента на сервер более одного файла, код не работает.
Какие исправления нужно внести в код, чтобы клиент мог передавать сразу несколько файлов, а сервер-принимать их?
Заранее спасибо за ответы!
