wpf 遍历所有控件？

Question

wpf 遍历所有控件？

Answer 1

打个比方，如果你想找一个wpf页面里所有TextBox，可以使用VisualTreeHelper的方法去找private void EnumVisual(Visual myVisual){for (int i = 0; i < VisualTreeHelper.GetChildrenCount(myVisual); i++){Visual childVisual = (Visual)VisualTreeHelper.GetChild(myVisual, i);if (childVisual != null){if (childVisual is TextBox) (childVisual as TextBox).Text = "Winner";EnumVisual(childVisual);}}}传参数的时候传this即可
