启用IgnorePatternWhitespace时，.NET正则表达式匹配空格字符

Question

I have a large regular expression and I've turned on IgnorePatternWhitespace so I can make it more readable. My problem is that I want to match a literal space character. What's the best way to do that?

An example:

Regex myRegex = new Regex(@"
  (?> <table[^>]*> ) # Find a table
  (?> .*?<tr> ) # Find the first row
  (?> .*?<th> ) # Find the first header column
  My phrase # Look for our key phrase
  etc.
", RegexOptions.IgnorePatternWhitespace);

In the above example, "My phrase" should include a space.

Answer 1

使用“\\ s”或“[]”

Answer 2

看起来您可以使用反斜杠简单地转义空格字符：

My\ phrase
