如何将 TextBlock 从 WPF 转换为 C# 中的字符串？
如何将 TextBlock 从 wpf 转换为 c# 中的字符串？我有一个包含文本块的列表框，以便更改前景色。但是当我得到 listbox.selecteditem 时，它显然返回一个文本块，但我需要知道文本块是什么，转换为字符串。我该怎么做？
How do you convert a TextBlock to a string in c# from wpf? i have a listbox that contains a textblock in order to change the foreground color. but when i get listbox.selecteditem, it obviously returns a textblock, but i need to know what the textblock is, converted into a string. how do i do that?

TextBlock.Text？编辑：引用我链接到的文档：
如果您现在仍然无法想出任何方法将文本从 TextBlock 中取出，那么...我什至不知道接下来该怎么做。
编辑：
这大约是您能得到的最模糊的信息。
开始回答（因为这并不明显）根据您的一些评论，您显然尝试根据从列表框获得的 TextBlock 重新构建信息。 TextBlock 确实（并且应该）不包含对象状态信息，如果您拥有的信息不仅仅是文本，您应该创建一个具有相应属性的新类，绑定到此类对象的集合，并且datatemplate 集合 适当地。这样 SelectedItem 将成为包含您需要的信息的类的对象，如果您编辑该信息，UI将反映这些变化。 TextBlock 不是顺势疗法设备。结束答案您在这个上接受的答案问题 在我看来，您只是不想费心学习数据绑定以及使 WPF 成为如此出色平台的所有内容。坚持容易出错的命令式 UI 创建的方法。采取 9001：
这个？

TextBlock.Text?Edit: To quote the documentation i linked to:
If you still cannot think of any way to get the text out of a TextBlock now then... i don't even know what then.
Edit:
This is about as vague as you can get.
Begin Answer (Since this was not apparent)Based on some of your comments you apparently try to recostruct information based on the TextBlock you get from a ListBox. TextBlocks do (and should) not contain object state information, if you have more information than just text you should create a new class with the respective properties, bind to a collection of such objects, and datatemplate the collection appropriately.That way the SelectedItem will be an object of the class which contains the information you need, and if you edit that information the UI will reflect those changes. TextBlocks are not homeopathic devices.End AnswerFrom what answer you accepted on this question it looks to me like you just don't want to bother learning about data binding and all the things that make WPF such a great platform. Way to cling to error-prone imperative UI creation.Take 9001:
This?
您无法将 TextBlock 转换为字符串。如果你指的是内容，请看HB的回答。
You can't convert a TextBlock to a string. If you mean the content, look H.B.'s answer.
