我的应用程序启动并绘制 MDI 父窗体。此时，它等待事件发生。为了启动主循环，用户必须单击工具栏按钮。这调用了主处理例程，这里是代码。
private void MainAPRSTW_Main()
{
//frmSplash objfrmSplash = new frmSplash();
//objfrmSplash.ShowDialog();
//this is the main list
TopNodeList MainList = new TopNodeList(this);
//setup the filter
FilterList CallFilter = new FilterList();
CallFilter.ReadPassList();
CallFilter.ReadBlockList();
//load what's in the cache
MainList.ReadCache(this);
//initiate the Socket
Socket server = new Socket(AddressFamily.InterNetwork,
SocketType.Stream,
ProtocolType.Tcp);
//initiate the endpoints
IPEndPoint AGWPEServer=new IPEndPoint(IPAddress.Parse(AGWIPAddress), AGWPort);
try
{
server.Connect(AGWPEServer);
}
catch (SocketException e)
{
System.Windows.Forms.MessageBox.Show("Unable to connect to server.");
junk = e.ToString();//this keeps the compiler from complaining
return;
}
//send command to enable monitor frames
try
{
server.Send(MonitorCommand, 36, SocketFlags.None);
}
catch (SocketException e)
{
System.Windows.Forms.MessageBox.Show("Unable to write monitor command.");
junk = e.ToString();//this keeps the compiler from complaining
return;
}
//-problem code starts here--------------------------------------------
while (TerminateFlag == false)
{
if (server.Available > 35)
{
//only go here if we have enough data available to process
//get the next header
TelemetryHeader.readHeader(server);
//read the rest of the packet and ignore
int recv = server.Receive(AGWServerData,
TelemetryHeader.MessageSize,
SocketFlags.None);
//Is it a telemetry packet?
if (Detector.isTelemetry(AGWServerData,TelemetryHeader.SourceCallsign))
{
if (CallFilter.Find(TelemetryHeader.SourceCallsign))
MainList.ProcessPacket(AGWServerData, Detector, this);
}
}//close If (server.Available).......
}//close while (terminateflag)......
//-problem code stops here-------------------------------------------
}//close MainAPRSTW_Main
您可以看到我在哪里描述了问题代码。如果我保留此代码，则子窗体只会部分填充，并且程序将无响应。这是一个屏幕截图。

如果我注释掉问题代码，所有子窗体都会绘制。这是那个屏幕截图。

所以对我来说很明显我需要做一些不同的事情。我猜这个循环太紧了。是这种情况还是有其他问题？
问题是，什么是正确的方法？我使用后台工作者吗？还有其他方法吗？
