WPF:如何处理后台工作人员的错误

呼叫Dispatcher.BeginInvoke。基本上,您需要这样的代码:

void UpdateState(WhatEverType someObject)
{
    if (! Dispatcher.CheckAccess())
    {
        Dispatcher.BeginInvoke(DispatcherPriority.Normal, new Action(()=>UpdateState(someObject));
    }
    else
    {
        //make the UI changes here.
    }
}
