newline character in c# string
提问by peter
I have some html code in a C# string. If I look with the Text Visualizer of Visual Studio I can see it has numerous newlines in it. However, after i apply this code
我在 C# 字符串中有一些 html 代码。如果我使用 Visual Studio 的 Text Visualizer 进行查看，我可以看到其中有许多换行符。但是，在我应用此代码后
string modifiedString = originalString.Replace(Environment.NewLine, "<br />");
and then I look with the Text Visualizer at modifiedString I can see it doesn't have anymore newlines except for 3 places. Are there any other character types than resemble newline and I am missing?
然后我用文本可视化器查看 modifiedString 我可以看到它除了 3 个地方外不再有换行符。除了类似换行符之外，还有其他字符类型吗？我失踪了吗？

They might be just a \ror a \n. I just checked and the text visualizer in VS 2010 displays both as newlines as well as \r\n.
它们可能只是一个\r或一个\n。我刚刚检查过，VS 2010 中的文本可视化器同时显示为换行符和\r\n.
This string
这个字符串
string test = "blah\r\nblah\rblah\nblah";
Shows up as
显示为
blah
blah
blah
blah
in the text visualizer.
在文本可视化工具中。
So you could try
所以你可以试试
string modifiedString = originalString
.Replace(Environment.NewLine, "<br />")
.Replace("\r", "<br />")
.Replace("\n", "<br />");

A great way of handling this is with regular expressions.
处理这个问题的一个好方法是使用正则表达式。
string modifiedString = Regex.Replace(originalString, @"(\r\n)|\n|\r", "<br/>");
This will replace any of the 3 legal types of newline with the html tag.
这将用 html 标记替换 3 种合法类型的换行符中的任何一种。
