使用BeginInvoke进行UI更新挂起，直到线程完成？
|
我有1个类（acBL），可处理2个线程（fpDoWork）。在fpDoWork中完成的任何工作都会触发一个事件回到acBL类。在我的表单上，我声明了acBL类并在acBL上关联了事件处理程序-这样，无论何时调用事件，它都“应该”使用更改来更新UI。
没有发生什么事，当每个fpDoWork线程启动时，它执行操作，然后调用ProcessingEvent并进入frmMain.handlerProcessing1事件。到达要点，调用this.BeginInvoke（new Processing2Event（handlerProcessing2），status），然后它挂起并等待线程完成工作，然后继续更新UI。我尝试了这个。调用，但是该方法似乎挂起了。有任何想法吗？
frmMain中的代码
之前的代码：
this.acBL.Processing1Event += new acBL.Processing1(handlerProcessing1);
this.acBL.Processing2Event += new acBL.Processing2(handlerProcessing2);
private void handlerProcessing1(string status) {
if (InvokeRequired) {
this.BeginInvoke(new MethodInvoker(this.Refresh));
this.BeginInvoke(new Processing1Event (handlerProcessing1), status);
}
else {
Console.WriteLine(\"UPDATING 1: \"+status);
lblForProcessing1.Text = status;
this.Refresh();
return;
}
}
private void handlerProcessing2(string status) {
if (InvokeRequired) {
this.BeginInvoke(new MethodInvoker(this.Refresh));
this.BeginInvoke(new Processing2Event (handlerProcessing2), status);
}
else {
Console.WriteLine(\"UPDATING 2: \"+status);
lblForProcessing2.Text = status;
this.Refresh();
return;
}
}
bool thread1Complete = false;
fpDoWork fpDoWork1 = new fpDoWork();
fpDoWork1.GUIForm = frmMain;
fpDoWork1.ProcessingEvent += new fpDoWork.Processing(handlerProcessing1Event);
fpDoWork1.ThreadCompleteEvent += new fpDoWork.ThreadComplete(thread1Complete);
Thread fpDoWork1Thread= new Thread(new ThreadStart(fpDoWork1.StartWork));
bool thread2Complete = false;
fpDoWork fpDoWork2 = new fpDoWork();
fpDoWork2.GUIForm = frmMain;
fpDoWork2.ProcessingEvent += new fpDoWork.Processing(handlerProcessing2Event);
fpDoWork2.ThreadCompleteEvent += new fpDoWork.ThreadComplete(thread2Complete);
Thread fpDoWork2Thread= new Thread(new ThreadStart(fpDoWork2.StartWork));
Console.WriteLine(\"Work for 1 Thread started...\");
fpDoWork1Thread.Start();
Console.WriteLine(\"Work for 2 Thread started...\");
fpDoWork2Thread.Start();
while (!thread1Complete && !thread2Complete ) {
if (!thread1Complete && !thread2Complete ) {
Console.WriteLine(\"Waiting for both copying threads...\");
}
else if (!thread1Complete && thread2Complete ) {
Console.WriteLine(\"Waiting for thread 1...\");
}
else if (thread1Complete && !thread2Complete ) {
Console.WriteLine(\"Waiting for thread 2...\");
}
Thread.Sleep(1000);
}
Console.WriteLine(\"All done\");
public delegate void ProcessingFor1 (string filename);
public delegate void ProcessingFor2 (string filename);
public event ProcessingFor1 ProcessingEventFor1;
public event ProcessingFor2 ProcessingEventFor2;
private void handlerProcessing1Event(string filename) {
Console.WriteLine(\"Processing 1: \" + filename);
ProcessingEventFor1(filename);
}
private void handlerProcessing1Event(string filename) {
Console.WriteLine(\"Processing 2: \" + filename);
ProcessingEventFor2(filename);
}
