我想知道是否有一种方法可以用 '\n' 替换所有 CRLF 实例。有办法实现吗？
I was wondering if there is a way to replace all instances of CRLF with '\n'. Is there a way to accomplish that?

你尝试过哪些方法不起作用？ CRLF 表示回车，行饲料。回车符为
\r，换行符为\n，因此用换行符替换 CRLF 将是这就像任何其他字符串替换一样。需要注意的是 Replace 是一个返回新字符串的方法，因此您需要将结果分配回某个变量，在大多数情况下，它可能与您已经使用的变量名称相同。
编辑：根据下面的评论，您可能会根据 Notepad++ 的行尾转换设置将 CRLF 误认为 LF。在十六进制编辑器中打开文件，看看里面到底有什么。您将看到 CRLF 为
0D 0A（因此回车符为0D，换行符为0A）。Notepad++ 将向您显示您想看到的内容。单击

Edit: based on your comment below, you are probably mistaking CRLF for LF based on Notepad++'s end of line conversion setting. Open your file in a hex editor to see what is really there. You will see CRLF as
0D 0A(so carriage return is0Dand line feed is0A).Notepad++ will show you what you want to see. Checked your end of line conversion by clicking

If you really want to replace a carriage return/linefeed pair with the explicit string "\n" you need to escape the backslash:
我认为看起来我一直在尝试以错误的方向进行替换。
