c# - 使用正则表达式匹配包含数字字母和破折号的字符串

我需要匹配此字符串011Q-0SH3-936729，而不是345376346或asfsdfgsfsdf
它必须包含字符，数字和破折号

模式可以是011Q-0SH3-936729或011Q-0SH3-936729-SDF3或000-222-AAAA或011Q-0SH3-936729-011Q-0SH3-936729-011Q-0SH3-936729-011Q-0SH3-936729，我希望它能够匹配任何一个。原因是我真的不知道格式是否固定，而且我也找不到办法，因此我需要为具有任意破折号的模式提出一个通用解决方案，并且该模式会重复出现任意数量的破折号。次。

抱歉，这可能是一个愚蠢的问题，但是我真的很讨厌正则表达式。

TIA

最佳答案

foundMatch = Regex.IsMatch(subjectString,
    @"^             # Start of the string
    (?=.*\p{L})     # Assert that there is at least one letter
    (?=.*\p{N})     # and at least one digit
    (?=.*-)         # and at least one dash.
    [\p{L}\p{N}-]*  # Match a string of letters, digits and dashes
    $               # until the end of the string.",
    RegexOptions.IgnorePatternWhitespace);

应该做你想做的。如果用字母/数字表示“仅ASCII字母/数字”（而不是国际/ Unicode字母），则使用

foundMatch = Regex.IsMatch(subjectString,
    @"^             # Start of the string
    (?=.*[A-Z])     # Assert that there is at least one letter
    (?=.*[0-9])     # and at least one digit
    (?=.*-)         # and at least one dash.
    [A-Z0-9-]*      # Match a string of letters, digits and dashes
    $               # until the end of the string.",
    RegexOptions.IgnorePatternWhitespace | RegexOptions.IgnoreCase);
