WPF:有没有办法直接获取控件所在的Window对象？

public static T FindVisualParent<T>(DependencyObject obj) where T : DependencyObject
{
    DependencyObject parent = VisualTreeHelper.GetParent(obj);
    while (parent != null && !(parent is T))
    {
        parent = VisualTreeHelper.GetParent(parent);
    }
    return parent as T;
}

Window window = FindVisualParent<Window>(control);

public static T FindLogicalParent<T>(DependencyObject obj) where T : DependencyObject
{
    DependencyObject parent = LogicalTreeHelper.GetParent(obj);
    while (parent != null && !(parent is T))
    {
        parent = LogicalTreeHelper.GetParent(parent);
    }
    return parent as T;
}

Window window = FindLogicalParent<Window>(control);
