在WPF窗口中按类型查找所有控件

这应该可以解决问题

public static IEnumerable<T> FindVisualChildren<T>(DependencyObject depObj) where T : DependencyObject{    if (depObj != null)    {        for (int i = 0; i < VisualTreeHelper.GetChildrenCount(depObj); i++)        { DependencyObject child = VisualTreeHelper.GetChild(depObj, i); if (child != null && child is T) {     yield return (T)child; } foreach (T childOfChild in FindVisualChildren<T>(child)) {     yield return childOfChild; }        }    }}

然后您像这样枚举控件

foreach (TextBlock tb in FindVisualChildren<TextBlock>(window)){    // do something with tb here}
