我晚上写了一个文件传输，比较简单。分发送方和接收方。在本机上测试之后，确实可以收到文件，但是会一直接收数据，导致获得的文件变得异常的大。请大家赐教，本人新手，可能写的地方有错误，请指出。谢谢。
//接收方代码。我把名称空间都删了，
namespace rece
{
    public partial class Form1 : Form
    {
        private Thread rece;
        private TcpListener tcplisten;
        private TcpClient tcpc;
        private NetworkStream ne;
        private FileStream fi;

        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {  
        }

        private void button1_Click(object sender, EventArgs e)
        {
            IPEndPoint ip = new IPEndPoint(IPAddress.Any, int.Parse(textBox1.Text));
            tcplisten = new TcpListener(ip);
            tcplisten.Start();
            rece = new Thread(new ThreadStart(receive));
            rece.SetApartmentState(ApartmentState.STA);
            rece.Start();
          }
        private void receive()
        {
            tcpc = tcplisten.AcceptTcpClient();
            ne = tcpc.GetStream();
            byte[] name=new byte[128];
            ne.Read(name,0,name.Length);
            string filename = Encoding.Unicode.GetString(name);
            saveFileDialog1 = new SaveFileDialog();
            saveFileDialog1.FileName = filename;
            saveFileDialog1.ShowDialog();
            string path = saveFileDialog1.FileName;
            fi = new FileStream(path,FileMode.Create);
            byte[] re = new byte[1];
            int count = ne.Read(re, 0, re.Length);
            while (count!=0)
            {
                fi.Write(re, 0, re.Length);
                ne.Read(re, 0, re.Length);
 
            }
            fi.Close();
            ne.Close();
            tcpc.Close();
            tcplisten.Stop();
            rece.Abort();
            this.Close();
           
        }
    }
}

//发送方
namespace CLIENT
{
    public partial class Form1 : Form
    {
        private NetworkStream s1;
        private TcpClient tcpclient=new TcpClient();

        private Thread thr;
        private FileStream f1;

        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }

        private void button1_Click(object sender, EventArgs e)
        {
            IPEndPoint ip = new IPEndPoint(IPAddress.Parse(textBox1.Text), int.Parse(textBox2.Text));
            TcpClient tcpclient = new TcpClient();
            tcpclient.Connect(ip);
            s1 = tcpclient.GetStream();
        }

        private void button2_Click(object sender, EventArgs e)
        {
            thr = new Thread(new ThreadStart(star));
            thr.SetApartmentState(ApartmentState.STA);
            thr.Start();

        }
        private void star()
        {

     

            if (openFileDialog1.ShowDialog() == DialogResult.OK)
            {
                FileInfo fi = new FileInfo(openFileDialog1.FileName);
                f1 = fi.OpenRead();
                string filename = fi.Name;
                byte[] se = new byte[128];
                se = Encoding.Unicode.GetBytes(filename.ToCharArray());
                s1.Write(se, 0, se.Length);
                int bytes;
                byte[] read = new byte[1];
                while (true)
                {
                  bytes = f1.Read(read, 0, read.Length);

                    if (bytes == 0)
                    {
                        break;
                    }

                     s1.Write(read, 0, read.Length);
                }

                f1.Close();
                s1.Close();
                tcpclient.Close();
                thr.Abort();
              
            }
        }
    }
}

自己顶一下，这不是水帖。

内阁请问你有网络编程这方面的视频吗?我想学学socket做局域网通信~发文字都没做明白~自学的这方面、现在只懂监听端口、以及链接服务端~~

接收方代码
int count = ne.Read(re, 0, re.Length);
while (count!=0)
{
    fi.Write(re, 0, re.Length);
    ne.Read(re, 0, re.Length);
}
当count不为0时进入while循环，这时count不为0，之后永远都不会为0，因为没有再为count赋过值了，while将永远执行下去。

那个，我也是自学的。看书的。看别人的代码。

恩，我知道了，谢了。
