C# 正则表达式从字符串中删除 BBCode 颜色

Question

string s = "I am an example of [color red]being colored[/color] at [color blue] any time[/color]";

如何检测所有 [color x] 和 [/color] 单词并将它们全部删除？

Answer 1

You can easily get the text with the below regex:

\[/?color\b[^][]*]

The regex matches:

• \\[/? - a literal [ and an optional / after it ( ? means 1 or 0 repetitions )
• color\\b - a whole word color ( \\b is a word boundary)
• [^][]* - 0 or more characters other than [ and ]
• ] - a literal ]

See IDEONE demo

string s = "I am an example of [color red]being colored[/color] at [color blue] any time[/color]";
Console.WriteLine(Regex.Replace(s, @"\[/?color\b[^][]*]", string.Empty));

Answer 2

Lucas Trzesniewski's solution works:

Regex.Replace(text, @"[/?color\\b.*?]", string.Empty)
