C# WPF：获取下一个/上一个可视对象

我有一个

堆栈面板

，其中包含许多

文本框

。有没有办法获取下一个/上一个视觉元素

---

我想要的功能相当类似于jQuery的

.next（）

函数，它可以获取下一个对象。

您可以尝试以下方法来枚举可视化树

public static IEnumerable<T> FindVisualChildren<T>
(DependencyObject depObj, string childName) where T : DependencyObject
{

    if (depObj != null)
    {
        for (int i = 0; i < VisualTreeHelper.GetChildrenCount(depObj); i++)
        {

            DependencyObject child = VisualTreeHelper.GetChild(depObj, i);
            var frameworkElement = child as FrameworkElement;
            if (child != null && frameworkElement.Name == childName)
            {
                yield return (T)child;
            }

            foreach (T childOfChild in FindVisualChildren<T>(child, childName))
            {
                yield return childOfChild;
            }
        }
     }
}
