how to ignore spaces in c# regex

Question

what is the c# equivalent of /x in perl for regex, so the /x at the end would ignore all the whitespaces newlines and whatnot in your regex expression. Otherwise, my expression would be a giant one liner instead of a little block. Any other way around it?

Answer 1

您正在寻找RegexOptions.IgnorePatternWhitespace 。

Answer 2

There's an option you can specify when constructing the Regex :

new Regex("...expression here...", RegexOptions.IgnorePatternWhitespace)

Since RegexOptions is a flag type, you can binary-OR this flag with any existing flags you may specify.

Answer 3

The /x inline character is supported. See here .
