WPF不同线程之间的控件是不同访问的，为了能够访问其他线程之间的控件，需要用Dispatcher.Invoke执行一个新的活动即可。
例如：
public void SetNotes(string notes)
{
if (Dispatcher.Thread != Thread.CurrentThread)
{
this.txtNote.Dispatcher.Invoke(new Action(() =>
{
this.txtNote.Text += notes;
this.txtNote.Text += "\r";
this.txtNote.ScrollToEnd();
}));
}
else
{
this.txtNote.Text += notes;
this.txtNote.Text += "\r";
this.txtNote.ScrollToEnd();
}
}
WinForm中：
private delegate void delegateCrossThread(string message); private void SetStatus(string message) { if (this.m_StatusLabel.InvokeRequired == true) { delegateCrossThread ct = new delegateCrossThread(SetStatus); this.Invoke(ct, new object[] { message }); } else { this.m_StatusLabel.Text = message; this.m_StatusLabel.Refresh(); } }
3、异步打开窗口
Thread newWindowThread = new Thread(new ThreadStart(ThreadStartingPoint)); newWindowThread.SetApartmentState(ApartmentState.STA); newWindowThread.Start(); private void ThreadStartingPoint() { SurveyStatWindow surveyStatDialog = new SurveyStatWindow(); if (m_StatDataTable != null) { surveyStatDialog.TimeData = m_StatDataTable; surveyStatDialog.Init(); } surveyStatDialog.ShowDialog(); }
4、全局异步调用
Application.Current.Dispatcher.Invoke(new Action(() =>
{
AddText();
}));
this.Dispatcher.Invoke(new Action(() =>
{
AddText();
}));
Application.Current.Dispatcher.Invoke(new Action(delegate { AddText();}));
