问题描述
我正在重写 PhoneTextBox 的样式，将默认背景更改为透明"，将前景更改为白色"，将边框刷更改为白色"，因为我想设计一个深色主题.
I'm rewriting the style for the PhoneTextBox, changing the default background to "transpanrent", the foreground to "White" and the BorderBrush to "White", because I want to design a Dark-Theme.
但是出现了一个问题，就是 text-input-indicator 消失了.我感谢原因是text-input-indicator的前景是黑色的，所以用户看不到它.但是我找不到定义文本输入指示器前景的方法.任何提示都将被应用.
But a problem came up that the text-input-indicator disappeared. I thank the reason is that the foreground of the text-input-indicator is black, so the user can't see it. But I can not find a way to define the foreground of the text-input-indicator. Any tips will be appricated.
附注.我不知道如何描述指标，所以我组成了文本输入指标"这个词，如下所示:
PS. I don't konw how to decribe the indicator, so I make up the word "text-input-indicator", which is shown below:
正常情况，黑色竖线出现.
Nomal situation,the black Vertical line shows up.
重写样式后，用户看不到黑色竖线:
After rewriting the style, the user can't see the black vertical line:

推荐答案
可能您正在寻找 CaretBrush、SelectionBackground 和 SelectionForeground.我不知道 toolkit:PhoneTextBox 中是否绑定了这些属性，但您绝对可以在任何情况下手动重新设置样式.
Probably you looking for CaretBrush, SelectionBackground and SelectionForeground. I don't know these properties are binded or not in toolkit:PhoneTextBox, but you definitely can restyle it manually in any case.
