cls_interface.localHost cls_interface._socketRev 是static的
这是接收的代码
cls_interface.localHost = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 8001);
cls_interface._socketRev = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
cls_interface._socketRev.Bind(cls_interface.localHost);
while (!cls_interface.IsStopRev)
{
if (!cls_interface.IsSuspendRev)
{
byte[] buffer = new byte[1024];
int len = 0;
IPEndPoint remoteEP = new IPEndPoint(IPAddress.Any, 0);
EndPoint Remote = (EndPoint)remoteEP;
len = cls_interface._socketRev.ReceiveFrom(buffer, ref Remote);
//获取读取到的信息
if (len > 0)
{
byte[] revbts = new byte[len];
for (int i = 0; i < len; i++)
{
revbts[i] = buffer[i];
}
get_udp_data(revbts);
pointsCount++;
}
}//判断是否暂停
}
这是发送代码
public void SendData()
{
double x = 0;
double i = 0;
while (true)
{
i+=0.5;
revdData revdata;
/* revdata 结构体赋值*/
//将结构体转换成byt[]
Type type = typeof(revdData);
int size = Marshal.SizeOf(type);
IntPtr buffer=Marshal.AllocHGlobal(size);
Marshal.StructureToPtr(revdata, buffer, false);
byte[] bts=new byte[size];
Marshal.Copy(buffer,bts,0,size);
double sd = Math.Sin(x);
_socket.SendTo(bts, new IPEndPoint(IPAddress.Parse("192.168.1.2"), 8001));
Marshal.FreeHGlobal(buffer);
Thread.Sleep(100);
x += 0.1;
}
}
