好吧,对于我的游戏,我设置了一个服务器/客户端对等连接,来回发送位置等。
尽管我的消息实际上并没有发送得那么快,而且也不可靠。由于部分字符串丢失,有时发送只是停止并且线程不继续(不知道为什么).t
无论如何,我的接收代码在这里:
public void RecieveAsync()
{
if (netStream == null) netStream = Server.GetStream();
if (netStream.DataAvailable == false) return;
netStream.BeginRead(ReadBuffer, 0, ReadBuffer.Length, new AsyncCallback(recieveCallBack), netStream);
}
public void recieveCallBack(IAsyncResult ar)
{
//try
//{
String content = String.Empty;
Console.WriteLine("Stuck trying to get data");
int rec = netStream.EndRead(ar);
if (rec > 0)
{
Console.WriteLine(Encoding.ASCII.GetString(
ReadBuffer, 0, rec));
string packet = Encoding.ASCII.GetString(
ReadBuffer, 0, rec);
bool completedPacket = false;
int appendTo = rec;
if (packet.Contains("<eof>"))
{
appendTo = packet.IndexOf("<eof>");
packet.Replace("<eof>", "");
completedPacket = true;
}
SB.Append(packet, 0, appendTo);
// Check for end-of-file tag. If it is not there, read
// more data.
content = SB.ToString();
if (completedPacket)
{
// All the data has been read from the
// client. Display it on the console.
if (DataRecieved != null)
{
string RecievedData = SB.ToString();
DataRecieved(RecievedData);
netStream.Flush();
Array.Clear(ReadBuffer, 0, ReadBuffer.Length);
ReadBuffer = new byte[1024];
}
SB.Clear();
// Echo the data back to the client.
}
else
{
// Not all data received. Get more.
Array.Clear(ReadBuffer, 0, ReadBuffer.Length);
ReadBuffer = new byte[1024];
netStream.BeginRead(ReadBuffer, 0, ReadBuffer.Length, recieveCallBack, netStream);
}
}
}
我的发送代码在这里:
public void Send(byte[] data, int index, int length)
{
//add data as state
//socket.NoDelay = true;
if (netStream == null) netStream = TcpClient.GetStream();
netStream.BeginWrite(data, 0, length, sendCallback, netStream);
}
private void sendCallback(IAsyncResult ar)
{
//try
//{
netStream.EndWrite(ar);
//if (ar.AsyncState != null)
//{
// byte[] buffer = (byte[])ar.AsyncState;
// socket.BeginSend(buffer, 0, buffer.Length, SocketFlags.None, sendCallback, null);
// return;
//}
if (OnSend != null)
{
OnSend(this);
}
netStream.Flush();
//catch (Exception ex)
//{
// System.Windows.Forms.MessageBox.Show(ex.ToString());
// return;
//}
}
数据包位于 Encoding.ASCII.Getbytes 下。
并且服务器和客户端都在使用 Thread.Sleep(1) 更新 while (true) 线程。
