我的游戏有两个客户端＆amp;一台服务器。 client1通过在服务器和服务器上放置数据将数据发送到client2。 client2从服务器检索。类似地，client2通过服务器向client1发送数据。
当我从Client1向client2发送数据时，一切都很好但是当client2向client1发送数据时，它会收到不相关的数据。
我认为在第一次通信期间，服务器上的任何数据都不是清除＆amp;因此，当Clien2将数据发送回client1时，数据与服务器上的数据重叠。发送不相关的数据。
我对所有客户端使用相同的代码，但是客户端代码的多个实例。
以下是我正在使用的代码： -
private void OnKeyDown1(object sender, KeyEventArgs e)
{
tbxno = 1;
if (e.Key == Key.Enter || e.Key == Key.Return)
{
// Disable further edit on textbox
playerTbx1.IsReadOnly = true;
// Compare answers entered by user
char[] letters = new char[playerTbx1.Text.Length];
StringReader sr = new StringReader(playerTbx1.Text);
sr.Read(letters, 0, playerTbx1.Text.Length);
int c = 0;
Console.WriteLine(word[i - 1]);
string label = MainWordLabel.Content.ToString();
while (label.Contains(letters[c].ToString()))
{
c++;
if (c == letters.Length)
break;
}
int count = c;
MessageBox.Show("No. of words matching : " + c);
// Score calculation
score += c * 5;
PlayerScoreTbx.Text = score.ToString();
//Send data to server
byte[] buffer = System.Text.Encoding.ASCII.GetBytes(playerTbx1.Text);
byte[] length = new byte[2];
length[0] = (byte)(playerTbx1.Text.Length % 256);
length[1] = (byte)(playerTbx1.Text.Length / 256);
byte[] usernameBuffer = System.Text.Encoding.ASCII.GetBytes(Username_Textbox.Text);
byte[] unamelength = new byte[2];
unamelength[0] = (byte)(Username_Textbox.Text.Length % 256);
unamelength[1] = (byte)(Username_Textbox.Text.Length / 256);
byte[] scoreBuffer = System.Text.Encoding.ASCII.GetBytes(PlayerScoreTbx.Text);
byte[] scoreLength = new byte[2];
scoreLength[0] = (byte)(PlayerScoreTbx.Text.Length % 256);
scoreLength[1] = (byte)(PlayerScoreTbx.Text.Length / 256);
byte[] tno = new byte[1];
tno[0] = (byte)tbxno;
tcpClient.Client.Send(length);
tcpClient.Client.Send(buffer);
tcpClient.Client.Send(unamelength);
tcpClient.Client.Send(usernameBuffer);
tcpClient.Client.Send(scoreLength);
tcpClient.Client.Send(scoreBuffer);
tcpClient.Client.Send(tno);
}
}
从服务器收回数据时： -
void getdata（） {
while (tcpsocket.Connected)
{
NetworkStream stream = tcpClient.GetStream();
byte[] userName = new byte[1024];
byte[] buffer = new byte[256];
byte[] length = new byte[2];
byte[] userlength = new byte[2];
byte[] scoreBuffer = new byte[1024];
byte[] scoreLength = new byte[2];
// read length of username
int readUserlength = stream.Read(userlength, 0, 2);
int userLength = userlength[0] + (userlength[1] * 256);
// read username
stream.Read(userName, 0, userLength);
string userReceived = System.Text.Encoding.ASCII.GetString(userName, 0, userLength);
// read length of score
int readUScore = stream.Read(scoreLength, 0, 2);
int lengthOfScore = scoreLength[0] + (scoreLength[1] * 256);
// read score
stream.Read(scoreBuffer, 0, lengthOfScore);
string score = System.Text.Encoding.ASCII.GetString(scoreBuffer, 0, lengthOfScore);
// check if the same client is not receiving data
this.Dispatcher.Invoke(() =>
{
if (userReceived.Equals(Username_Textbox.Text) == false)
{
int readlength = stream.Read(length, 0, 2);
int dataLength = length[0] + (length[1] * 256);
stream.Read(buffer, 0, dataLength);
string data = System.Text.Encoding.ASCII.GetString(buffer,0,dataLength);
byte[] tbox = new byte[1];
stream.Read(tbox, 0, 1);
int count = tbox[0];
this.Dispatcher.Invoke(() =>
{
OppTbx1.Text = data;
OppScoreTbx.Text = score;
});
}
});
}
}
服务器上的代码： -
public delegate void Disconnected（ClientManager item）;
public delegate void MessageReceived(string item, string username, string score, byte textbox);
public class ClientManager
{
public Socket socket { get; set; }
private NetworkStream networkStream;
public event Disconnected OnDisconnected;
public event MessageReceived OnMessage;
public ClientManager(Socket clientSocket)
{
this.socket = clientSocket;
this.networkStream = new NetworkStream(this.socket);
Task.Factory.StartNew(() =>
{
while (socket.Connected)
{
// TextBox Data
byte[] dataBuffer = new byte[1024];
byte[] length = new byte[2];
int readlength = this.networkStream.Read(length, 0, 2);
if (readlength == 0)
break;
int dataLength = length[0] + (length[1] * 256);
int readDataBytes = this.networkStream.Read(dataBuffer, 0, dataLength);
if (readDataBytes == 0)
break;
string data = System.Text.Encoding.ASCII.GetString(dataBuffer, 0, dataLength);
// Username Information
byte[] username = new byte[1024];
byte[] userlength = new byte[2];
int readLengthbytes = this.networkStream.Read(userlength, 0, 2);
if (readLengthbytes == 0)
break;
int userLength = userlength[0] + (userlength[1] * 256);
int readUsername = this.networkStream.Read(username, 0, userLength);
if (readUsername == 0)
break;
string usernameString = System.Text.Encoding.ASCII.GetString(username, 0, userLength);
// score
byte[] scoreBuffer = new byte[1024];
byte[] scorLength = new byte[2];
int readscorelength = this.networkStream.Read(scorLength, 0, 2);
if (readscorelength == 0)
break;
int lenghtOfScore = scorLength[0] + (scorLength[1] * 256);
int readscore = this.networkStream.Read(scoreBuffer, 0, lenghtOfScore);
if (readscore == 0)
break;
string score = System.Text.Encoding.ASCII.GetString(scoreBuffer, 0, lenghtOfScore);
byte[] tbx = new byte[1];
this.networkStream.Read(tbx,0,1);
//send data,sername & score
OnMessage(data, usernameString, score, tbx[0]);
}
//socket.Disconnect(false);
if (OnDisconnected != null)
OnDisconnected(this);
});
}
}
}
向客户发回： -
void SendChatMessage（字符串消息，字符串用户名，字符串分数，字节tbox） { byte [] data = System.Text.Encoding.ASCII.GetBytes（message）; byte [] length = new byte [2]; length [0] =（byte）（message.Length％256）; length [1] =（byte）（message.Length / 256）;
byte[] usernameBuffer = System.Text.Encoding.ASCII.GetBytes(username);
byte[] userlength = new byte[2];
userlength[0] = (byte)(username.Length % 256);
userlength[1] = (byte)(username.Length / 256);
byte[] scoreBuffer = System.Text.Encoding.ASCII.GetBytes(score);
byte[] scoreLength = new byte[2];
scoreLength[0] = (byte)(score.Length % 256);
scoreLength[1] = (byte)(score.Length / 256);
byte[] tbxCount = new byte[1];
tbxCount[0] = tbox;
Task.Factory.StartNew(() =>
{
lock (tcpClients)
{
foreach (var item in tcpClients)
{
try
{
item.socket.Send(userlength);
item.socket.Send(usernameBuffer);
item.socket.Send(scoreLength);
item.socket.Send(scoreBuffer);
item.socket.Send(length);
item.socket.Send(data);
item.socket.Send(tbxCount);
}
catch (Exception ex)
{
ex.GetBaseException();
}
}
}
});
}
}
答案 0 :(得分：0)
正如在这些问题中看到的那样，你忽略了Read()返回的计数，并假设读取填充了缓冲区。没有指定这样做，或者传输任何多于一个字节：非阻塞模式下的零字节。您需要循环，直到您拥有所需或所需的所有数据。
