问题描述
当我试图将控件添加到我的UserControl列表时，它抛出调用线程无法访问此对象，因为另一个线程拥有它。例外。
panel_PanelHolder.Children.Clear（）;
panel_PanelHolder.Children.Add（usr_panel） ;
但是当我使用下面的代码时，
Dispatcher.BeginInvoke（DispatcherPriority.Background，new Action（（）=>
{
panel_PanelHolder.Children.Clear（）;
panel_PanelHolder.Children.Add（usr_panel）;
}））;
它抛出调用目标引发了异常。例外。
我需要的是清除控件，并向面板添加一个控件。我不确定如何尽快解决这个问题。我正在使用STA线程动态操作WPF窗口控件。有人可以帮我吗？
谢谢
While I was trying to add Controls to my UserControl list it threw "The calling thread cannot access this object because a different thread owns it." exception.
panel_PanelHolder.Children.Clear();
panel_PanelHolder.Children.Add(usr_panel);
But when I used below code,
Dispatcher.BeginInvoke(DispatcherPriority.Background, new Action(() =>
{
panel_PanelHolder.Children.Clear();
panel_PanelHolder.Children.Add(usr_panel);
}));
It throws "Exception has been thrown by the target of an invocation." exception.
What I need is to clear controls, and add a control to the panel. I''m not sure how to fix this ASAP. I''m using a STA thread to manipulate WPF window controls dynamically. Can someone help me on this?
Thanks
