正则表达式的问题 [英] problem with regular expressions

问题描述

请帮助解决我的下列问题。

Hi,
please, kindly help to solve my following problem.

string str = "\"phone-number\"";
           string str1 = "<div class=" + str + ">" + "(101) 1010-1234" + "</div>";

           string str2 = "<div class=\"phone-number\"><\\(\\d{3}\\) \\d{3}\\-\\d{4}/div>";



           Match _match = Regex.Match(str1, str2);

           string value = _match.Value;

           Console.WriteLine(value);

我没有得到任何价值。

拜托，如果我错了，请帮我纠正我的代码。

推荐答案

Ahem：

Ahem:

string str1 = "<div class=" + str + ">" + "(101) 1010-1234" + "</div>";
string str2 = "<div class=\"phone-number\"><\\(\\d{3}\\) \\d{3}\\-\\d{4}/div>";

仔细观察：

Look closely:

\\d{3}\\-\\d{4}

是三位数，后跟一个连字符，后跟四位数。

Is three digits, followed by a hyphen, followed by four digits.

1010-1234

四位数后跟一个连字符，后跟四位数。



获取 Expresso [ ^ ] - 它是免费的，它会检查并生成正则表达式。

Is four digits, followed by a hyphen, followed by four digits.
