大家下午好！
项目目标：构建一个带有客户端、控制台和服务器可执行文件的通知程序。只有选定的用户才能收到通知。
问题：有时代码运行良好，一切正常（20% 的运行）。其余时间，它会弄乱数据发送的顺序。
代码：服务器（控制台 = TCPclient）：
private void Connect()
{
string username = ReadFromConsole();
if (IsUserAllowed(username)) // Receive username
SendToConsole(bool.TrueString); // Send confirmation
else
{
SendToConsole(bool.FalseString); // Send denial
console.Close();
return;
}
string messageID = ReadFromConsole(); // Receive MessageID
string recipientCount = ReadFromConsole();
int numOfRecipients = int.Parse(recipientCount); // Receive and parse number of recipients
List<string> recipients = new List<string>();
for (int i = 0; i < numOfRecipients; i++)
{
string recipient = ReadFromConsole();
recipients.Add(recipient); // Receive recipient, add to list (required for Message)
}
string department = ReadFromConsole(); // Receive department string
string visibleTime = ReadFromConsole(); // Receive visibility timespan
string expiration = ReadFromConsole(); // Receive expiration datetime
StoreRTF(messageID); // Receive and store RTF file
console.Close(); // Connection is done, close
Message message = new Message(messageID, department, recipients, visibleTime, expiration);
}
控制台（服务器 = TCPclient）：
private void SendMessage()
{
SendToServer(Environment.UserName);
if (bool.Parse(ReadFromServer()))
{
// User is allowed, continue
string messageID = DateTime.Now.ToUniversalTime().Ticks.ToString();
SendToServer(messageID); // MessageID
string recipientCount = lvRecipients.Items.Count.ToString();
SendToServer(lvRecipients.Items.Count.ToString()); // Amount of recipients
foreach (string item in lvRecipients.Items) // Loop to send each recipient
{
SendToServer(item);
}
string department = TB_Department.Text;
SendToServer(department); // Send department string
string visibleTime = TimeSpan.FromSeconds(SLIDER_VisibleTime.Value).Ticks.ToString();
SendToServer(visibleTime); // Send message visibility time
string expiration = DateTime.Now.ToUniversalTime().AddMinutes(2).ToString();
SendToServer(expiration); //TODO add UI control for this
SendRTFToServer(); // Send RTF file
MessageBox.Show(
"Your designated MessageID is: " + messageID + Environment.NewLine +
"Message upload is succesful.",
"Complete",
MessageBoxButton.OK);
}
else
{
// User is not allowed. Report to user. Disconnect (will be managed by the finally block)
MessageBox.Show("You are not allowed to upload messages to the server.", "Access denied", MessageBoxButton.OK, MessageBoxImage.Stop);
return;
}
}
发送和接收部分（控制台/服务器/客户端之间相同）：
private void SendToServer(string toSend)
{
while (server.GetStream().DataAvailable)
{
// Should wait
}
StreamWriter writer = new StreamWriter(server.GetStream());
writer.WriteLine(toSend);
writer.Flush();
}
private void SendRTFToServer()
{
while (server.GetStream().DataAvailable)
{
// Should wait
}
File.Open(RTFLocation, FileMode.Open, FileAccess.Read).CopyTo(server.GetStream());
server.GetStream().Flush();
server.GetStream().Close();
}
private string ReadFromServer()
{
server.GetStream().Flush();
StreamReader reader = new StreamReader(server.GetStream());
return reader.ReadLine();
}
我也尝试过不同的循环、实现、切换到 byte[]...
经过大量调试后，我一无所获。我已经检查了哪些信息正在离开控制台，并且所有信息都已签出并且顺序正确。但是，在服务器端，它似乎以完全不同的顺序接收它。
有人知道是什么原因造成的吗？
