我需要一些关于Powershell和WPF的帮助。
我正在修改某人使用WPF和PowerShell创建的加载项。因此，我不能100％确定xaml结构是如何布局的。我想要做的是修改运行时生成的某个元素的Text属性。我使用了Snoop2.8.0并找到了我要修改的元素，它有一个Name属性＆＃34; FreeTextBox＆＃34;。我打算使用FindName方法来获取元素，但FindName方法不返回任何内容。
我在一些帖子中读到有一个名为contentPresenter的单独的东西，其中存储了这些运行时元素，我需要引用它来到我的文本框，但是，我不知道如何做到这一点。如果有人能指出我正确的方向，我将不胜感激。
此致 伊利亚斯

从第二个代码的最后一行可以看出，我试图使用findname来获取从主应用程序创建的FreeTextBox。不幸的是，我没有创建文本框的代码，因为这是一个从主应用程序调用的插件。我使用snoop来找出元素本身的属性，但是堆栈还不允许我发布图像。
答案 0 :(得分：0)
FreeTextBox可能在另一个用户控件或datatemplate中加载到您的窗口，因此位于不同的NameScope中。 FindName仅在当前的名称范围内查找元素。
您需要使用VisualTreeHelper API以递归方式遍历窗口的整个可视子树，并检查每个元素的name属性以便找到FreeTextBox。只需使用GetChildrenCount和GetChild方法。
