在TCP套接字上丢失一个字节

Question

public class Packet
{
    public byte[] Buffer;

    public Packet(string message)
    {
        Buffer = new byte[255];

        byte[] messageArray = Encoding.ASCII.GetBytes(message);

        Buffer[0] = (byte)messageArray.GetLength(0);

        for (int i = 0; i < messageArray.GetLength(0); i++)
        {
            Buffer[i+1] = messageArray[i];
        }

    }
    public Packet(byte[] buffer)
    {
        Buffer = buffer;
    }
    public string GetMessage()
    {
        List<byte> messageBuffer = new List<byte>();

        for (int i = 1; i <= Buffer[0]; i++)
        {
            messageBuffer.Add(Buffer[i]);
        }

        return Encoding.ASCII.GetString(messageBuffer.ToArray());
    }

}

class Client
{
    public static List<Client> connectedClients = new List<Client>();
    public Socket Sock;
    public byte[] Buffer = new byte[255];

    public Client(Socket pSock)
    {
        Sock = pSock;
        Sock.BeginReceive(Buffer, 0, 255, SocketFlags.None, new AsyncCallback(RecieveCallBack), null);
    }

    public void Send(byte[] pBuffer)
    {
        Sock.BeginSend(pBuffer, 0, pBuffer.GetLength(0), SocketFlags.None, new AsyncCallback(SendCallBack), null);
    }

    public void SendCallBack(IAsyncResult AR)
    {
        Console.WriteLine("Sent");
        Sock.EndSend(AR);
    }
    public void RecieveCallBack(IAsyncResult AR)
    {
        Sock.EndReceive(AR);

        Packet recPacket = new Packet(Buffer);
        Console.WriteLine(recPacket.GetMessage());

        Sock.BeginReceive(Buffer, 0, 255, SocketFlags.None, new AsyncCallback(RecieveCallBack), null);
    }
}

    public Client(Socket pSock)
    {
        Sock = pSock;
        Sock.BeginReceive(Buffer, 0, 255, SocketFlags.None, new AsyncCallback(RecieveCallBack), null);
    }

    public void Send(byte[] pBuffer)
    {
        Sock.BeginSend(pBuffer, 0, pBuffer.Length, SocketFlags.None, new AsyncCallback(SendCallBack), null);
    }

    public void SendCallBack(IAsyncResult AR)
    {
        Console.WriteLine("Sent");
        Sock.EndSend(AR);
    }
    public void RecieveCallBack(IAsyncResult AR)
    {
        Sock.EndReceive(AR);

        Packet recPacket = new Packet(Buffer);
        Console.WriteLine(recPacket.GetMessage());

        Sock.BeginReceive(Buffer, 0, 255, SocketFlags.None, new AsyncCallback(RecieveCallBack), null);
    }
}`

已解决

错误是在发送方法中，我没有包括。

sock.BeginSend(sentBuffer[0].Buffer, 0, sentBuffer[0].Buffer[0], SocketFlags.None, new AsyncCallback(SendCallBack), null);

sentBuffer是一个列表，是一个队列。我把它改成了255,它工作了
