Question

我只是想问为什么当我尝试发送一个字节时，它根本没有发送，我做了一个简单的程序，不知道为什么它现在正在工作（在客户端和服务器中发送属性）这是我的服务器端代码

    public void ServerStartReceiving()
    {
        sck = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
        sck.Bind(new IPEndPoint(0, 1980));
        sck.Listen(0);
        acc = sck.Accept();
        sck.Close();
        new Thread(() =>
        {
            while (true)
            {
                byte[] sizeBuff = new byte[4];
                acc.Receive(sizeBuff, 0, sizeBuff.Length, 0);
                int size = BitConverter.ToInt32(sizeBuff, 0);
                MemoryStream ms = new MemoryStream();

Answer 1

这是最明显的错误：

                while (read != buffer.Length)
                {
                    read += ns.Read(buffer, 0, buffer.Length);
                }

1）如果您已经读过一些字节，则不想读入buffer。你需要读入缓冲区的正确部分。

2）您不想阅读buffer.Length个字节。你想读取你还没读过的很多字节。

C＃发送字节不起作用
