不接收客户端上的所有数据

Question

可能的重复：
C# Begin/EndReceive - 如何读取大数据？
C# 异步套接字服务器接收问题

我在套接字上编写了异步客户端和服务器应用程序（TCP）。例如，当我从服务器发送 300000 字节时，我在客户端仅收到其中的一部分。然后我再次调用 Receive 方法并接收其余数据。虽然Receive方法必须接收所有数据。问题是什么？

Here the code of the Receive method on client side:

 public class ConnectionInfo
 {
        public Socket _socketReply;
        public Socket _SocketCommand;
        public byte[] _bufferSendReply;
        public byte[] _bufferReceive;
        public byte[] _bufferSendCommand;
        public int _numberBytesSentReply = 0;
        public int _numberBytesSentCommand = 0;
        public List<byte> _fullBufferReceive;
        public uint _id = 0;

        public ConnectionInfo()
        {
            _fullBufferReceive = new List<byte>();
        }
 }

 private void RecieveCallback(IAsyncResult asyncResult)
    {
        ConnectionInfo connection = (ConnectionInfo)asyncResult.AsyncState;
        try
        {
            int bytesRead = connection.Socket.EndReceive(asyncResult);

            if (bytesRead > 0)
            {
                for (int i = 0; i < bytesRead; i++)
                    connection.FullBufferReceive.Add(connection.BufferReceive[i]);
                if (bytesRead == connection.BufferReceive.Length)
                {
                    connection.Socket.BeginReceive(connection.BufferReceive, 0, connection.BufferReceive.Length, 0,
                                                   new AsyncCallback(RecieveCallback), connection);
                    Console.WriteLine("Bytes recieved -- " + bytesRead + " by " + connection.Id);
                }
                else
                {
                    Console.WriteLine("All -- Bytes -- recieved " + bytesRead + " by " + connection.Id);

                    ConnectionInfo NewCI = new ConnectionInfo(connection);
                    Recieve(connection);
                    _serverController.SpreadReceivedData(NewCI);
                }
            }
            else
                CloseConnection(connection);
        }
        catch (ObjectDisposedException ode)
        {
            CloseConnection(connection);
            Console.WriteLine("ObjectDisposedException: " + ode.Message);
        }
        catch (SocketException exc)
        {
            CloseConnection(connection);
            Console.WriteLine("Socket exception: " + exc.SocketErrorCode);
        }
        catch (Exception e)
        {
            CloseConnection(connection);
            Console.WriteLine(e.ToString());
        }
    }

 public void Recieve(ConnectionInfo connection)
 {
        try
        {
            connection.BufferReceive = new byte[Settings.bufferLength];
            connection.FullBufferReceive.Clear();
            connection.NumberBytesSentReply = 0;

            connection.Socket.BeginReceive(connection.BufferReceive, 0, connection.BufferReceive.Length, 0,
                                          new AsyncCallback(RecieveCallback), connection);
        }
        catch (SocketException exc)
        {
            CloseConnection(connection);
            Console.WriteLine("Socket exception: " + exc.SocketErrorCode);
        }
        catch (Exception e)
        {
            Console.WriteLine(e.ToString());
        }
    }
