如何在WPF中获得顶层对象(窗口或页面)[[副本]

这对我很有用:

Window parentWindow = Window.GetWindow(this);

var parent = VisualTreeHelper.GetParent(this);
while (!(parent is Page))
{
    parent = VisualTreeHelper.GetParent(parent);
}
(parent as Page).DoStuff();

可以使用VisualTreeHelper类检索顶级控件:

DependencyObject GetTopLevelControl(DependencyObject control)
{
    DependencyObject tmp = control;
    DependencyObject parent = null;
    while((tmp = VisualTreeHelper.GetParent(tmp)) != null)
    {
        parent = tmp;
    }
    return parent;
}

我认为最好的办法是

var obj = VisualTreeHelper.GetParent((DependencyObject)Content);
