新线的定期到期？ [英] Regular expiration for new line?

问题描述

我希望正则表达式在第5个空格后换成新行吗？

它会一直持续到文件结尾...

I Want regex for after 5th white space replace into new line?
it will be continue up to end of file...

推荐答案

在正则表达式中，新行也是一个空格，所以你可能意味着空间（或者也可能是制表符）...

In regular expression new line is also a whitespace, so you probably meant space (or maybe tab too)...

string szOriginal = "whatever you have";
string szPattern = "[ \t]{5,}" // space or tab, 5 or more in a row...
Regex oRegex = new Regex(szPattern);
string szResult = oRegex.Replace(szOriginal , Environment.NewLine);
