我有一个Paragraph对象,我尝试从与创建它不同的线程访问,然后发布我的问题在此处搜索一个在线解决方案,我发现了“Dispatcher”解决方案,这对我来说不管用。调用线程无法访问此对象,因为不同的线程拥有它,即使在使用调度程序时

下面的代码:

Run r = new Run((string)name + Environment.NewLine); 
r.Foreground = Brushes.Green; 
Dispatcher.Invoke(new Action(() => { currentlyOnlineParagraph.Inlines.Add(r); }), DispatcherPriority.ContextIdle); 

我得到这个错误:

InvalidOperationException was unhandled 
An unhandled exception of type 'System.InvalidOperationException' occurred in mscorlib.dll 
Additional information: The calling thread cannot access this object because a different thread owns it.

我怎样才能解决这个问题?

从代码,我看到了几行字,我会尝试在图形线程上创建的所有图形对象,包括Run对象:

Dispatcher.Invoke(new Action(() => { 
    Run r = new Run((string)name + Environment.NewLine); 
    r.Foreground = Brushes.Green; 
    currentlyOnlineParagraph.Inlines.Add(r); 
}), DispatcherPriority.ContextIdle);
