我最近再玩網路連線時，遇到了一些問題
我的程式 可以自己連自己
可是卻無法使用2台區網內的電腦進行連線
以下是我的CODE
************************
Server端
************************
private void button1_Click(object sender, EventArgs e)
{
threadA = new Thread(new ThreadStart(UDPserverBMP));
threadA.Start();
}
private void UDPserverBMP()
{
IPEndPoint ipeq = new IPEndPoint(IPAddress.Any, 5555);
Socket newsock = new Socket(AddressFamily.InterNetwork,
SocketType.Dgram, ProtocolType.Udp);
newsock.Bind(ipeq);
while (true)
{
this.Invoke((shoeinformation)delegate
{
listBox1.Items.Add("Wait.....");
});
IPEndPoint Asender = new IPEndPoint(IPAddress.Any, 5555);
EndPoint Remote = (EndPoint)Asender;
byte[] tmp = new byte[50];
int recv = newsock.ReceiveFrom(tmp, ref Remote);
string str = (string)Deserialize(tmp);
try
{
byte[] data = new byte[109182];
Bitmap bmp = new Bitmap(160, 120);
Graphics g = Graphics.FromImage(bmp);
g.Clear(Color.Black);
data = Serialize(bmp);
newsock.SendTo(data, Remote);
data = null;
this.Invoke((shoeinformation)delegate
{
listBox1.Items.Add("___________________________");
listBox1.Items.Add("Okay!!!");
listBox1.Items.Add("GET"+str);
listBox1.Items.Add("接收時所用的");
listBox1.Items.Add(ipeq.Address.ToString());
listBox1.Items.Add(ipeq.Port.ToString());
listBox1.Items.Add("");
listBox1.Items.Add("___________________________");
});
}
catch (Exception e)
{
MessageBox.Show(e.ToString());
}
}
}
***************************************
Client
***************************************
private void button1_Click(object sender, EventArgs e)
{
threadA = new Thread(new ThreadStart(UDPgetBMP));
threadA.Start();
}
private void UDPgetBMP()
{
try
{
byte[] data = new byte[1024 * 1024 * 8];
IPEndPoint ipep = new
IPEndPoint(IPAddress.Parse("192.168.1.3"), 5555);
Socket server = new Socket(AddressFamily.InterNetwork,
SocketType.Dgram, ProtocolType.Udp);
string str="this is client";
byte[] buffer = Serialize((object)str);
server.SendTo(buffer, buffer.Length, SocketFlags.None,
ipep);
IPEndPoint Asender = new
IPEndPoint(IPAddress.Parse("192.168.1.3"), 5556);
EndPoint Remote = (EndPoint)ipep;
int rece = server.ReceiveFrom(data, ref Remote);
object tmp = Deserialize(data);
this.Invoke((showinformation)delegate
{
pictureBox1.Image = (Bitmap)tmp;
});
}
catch (Exception e)
{
MessageBox.Show(e.ToString());
}
}

在區網內進行連線時就無法連線
懇請各位大大們為我解答

錯誤訊息是
遠端主機已強制關閉一個現存的連線。...
