遍历WPF窗体元件的两种方法

1、使用VisualTreeHelper

public static void Scan(object AComponent){    if (!(AComponent is DependencyObject)) return;    int vCount = VisualTreeHelper.GetChildrenCount((DependencyObject)AComponent);    for (int i = 0; i < vCount; i++)    {        DependencyObject vChild = VisualTreeHelper.GetChild((DependencyObject)AComponent, i);        Scan(vChild);    }}

2、使用反射获取未公开的属性

public static void Scan(object AComponent){    PropertyInfo FI;    MethodInfo MI;    Visual vChild;    int vCount;    UIElement u;    FI = AComponent.GetType().GetProperty("VisualChildrenCount", BindingFlags.Instance | BindingFlags.NonPublic);    MI = AComponent.GetType().GetMethod("GetVisualChild", BindingFlags.Instance | BindingFlags.NonPublic);    if ((FI != null) && (MI != null))    {        vCount = (int)FI.GetValue(AComponent, null);        for (int i = 0; i < vCount; i++)        {            object[] vParams = new object[1];            vParams[0] = i;            vChild = (Visual)MI.Invoke(AComponent, vParams);            Scan(vChild);        }    }}
