怎样使用TCP在服务器和客户端传输大量得图片文件？

[thymelaea]

有谁做过类似得工作，在服务器和客户端建立TCP通道，然后由服务器给客户端传输图片文件，每次传输得大小大约是20M左右，这里是我写得代码，但是传到客户端之后文件里边就为空了，有谁知道为什么嘛？
private void Form1_Load(object sender, System.EventArgs e)
{
Thread tcp=new Thread(new ThreadStart(ThreadedTcpSrvr1));
tcp.IsBackground=true;
tcp.Start();
}
public Socket server;
public string stringdata;
public void ThreadedTcpSrvr1()
{
client=new TcpListener(IPAddress.Parse("192.168.10.54"),5801);
client.Start();
while(true)
{
while(!client.Pending())
{
Thread.Sleep(2000);
}
threadlistener=client;
Thread newthread=new Thread(new ThreadStart(HandleConnection));
newthread.IsBackground=true;
newthread.Start();
}
}

public void HandleConnection()
{
TcpClient tcpclient=threadlistener.AcceptTcpClient();
NetworkStream ns=tcpclient.GetStream();
FileStream fs=new FileStream("d:\\ff.yaan",FileMode.Open,FileAccess.Read);
byte[] send=new byte[2229888];
BinaryReader br=new BinaryReader(fs);
fs.Read(send,0,send.Length-1);
br.Read(send,0,send.Length-1);
ns.Write(send,0,send.Length-1);
ns.Close();
tcpclient.Close();
}
以上是服务器端得发送代码

private bool connect()
{
IPEndPoint ipep=new IPEndPoint(IPAddress.Parse("192.168.10.54"),5801);
client1=new Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp);
try
{
client1.Connect(ipep);
return true;
}
catch
{
return false;
}
}
if(connect()==true)
{
FileStream fs=new FileStream("d:\\f1.yaan",FileMode.Create);
byte[] receive=new byte[229888];
BinaryWriter bw=new BinaryWriter(fs);
client1.Receive(receive);
fs.Write(receive,0,receive.Length);
bw.Write(receive,0,receive.Length);
fs.Close();
bw.Close();
client1.Close();
以上是客户端得代码
分不够可以再加！！

自己顶一下，怎么没有人回答啊

up

你得把文件分成固定大小的包再进行传送

[thymelaea]

能说得具体点嘛？我试着把它分成1000个字节逐次发送，但是接收端如何接收呢？我那样试后什么都接不到了啊

让我想想呀，没搞过这个。

FileMode.OpenorCreate

应该比较easy，帮你看看

Sorry,I'll tell you the result tommorrow.

先接一下分

1
//while(true)
// {
while(!client.Pending())
{
Thread.Sleep(2000);
}
threadlistener=client;
Thread newthread=new Thread(new ThreadStart(HandleConnection));
newthread.IsBackground=true;
newthread.Start();
// }


2

//fs.Read(send,0,send.Length-1);
br.Read(send,0,send.Length);
ns.Write(send,0,send.Length);


3
client1.Receive(receive);
//fs.Write(receive,0,receive.Length);
bw.Write(receive);//,0,receive.Length);
