推荐答案

我认为您在评论中有足够的提示问题。



您已经知道如何使用 SelectionStart 和 SelectionLength <来控制选择/ code>。您也可以使用它： https：// msdn。 microsoft.com/en-us/library/system.string.split%28v=vs.110%29.aspx [ ^ ]。



最后一个问题是用于行尾字符的内容。不幸的是，它们依赖于平台： http://en.wikipedia.org/wiki/Newline [ ^ ]。



因此，您需要使用此属性： https：/ /msdn.microsoft.com/en-us/library/system.environment.newline%28v=vs.110%29.aspx [ ^ ]。



现在你知道解决问题的一切。现在，轮到你了。

I think you got enough hints in the comments to the question.

You already know how to control selection with SelectionStart and SelectionLength. You also can use this: https://msdn.microsoft.com/en-us/library/system.string.split%28v=vs.110%29.aspx[^].

The final problem is what to use for end-of-line characters. Unfortunately, they are platform-dependent: http://en.wikipedia.org/wiki/Newline[^].

So, you need to use this property: https://msdn.microsoft.com/en-us/library/system.environment.newline%28v=vs.110%29.aspx[^].

Now you know everything to solve the problem. Now, it's your turn.
