Question

现在我正在使用这段代码：

public static bool ContainsEmoji(this string text)
{
    Regex rgx = new Regex(@"\p{Cs}");
    return rgx.IsMatch(text);
}

它有点帮助。

其中大多数似乎被检测到，但有些则没有。

这是一个帮助的参考列表：http://unicode.org/emoji/charts/full-emoji-list.html

所有的笑脸看起来都很好，但这些特定的表情符号并没有被正则表达式所吸引：

1920 U +2614☔带雨滴的雨伞

1921 U +26F1⛱在地上的伞

1922年U +26A1⚡高压

1923年U + 2744❄雪花

在键盘上这些并不是彼此靠近，但是在列表中它们是相互跟随的，所以我只是假设有一个点它将开始不在表情符号列表中工作，并且它并没有真正验证。从1905年（天气般的表情符号），下降，一些被捕获在正则表达式，一些不是。似乎没有任何规则。

我无法承担全部ASCII码，因为我需要人们输入西里尔字符等字符，但我不能特别接受表情符号。我不知道如何从这里前进。

我读了MSDN docs about surrogates high/low pairs，但在这个阶段，这对我来说非常混乱，我认为一些正确方向的推动会有很长的路要走。

非常感谢您的时间：）

您可以使用以下正则表达式匹配Emoji Keyboard/Display Test Data for UTR #51 (Version: 11.0)文件中定义的所有3518表情符号字符：

Unicode 技术标准 #51 根据 Unicode 字符属性定义了 a regular expression pattern for detecting Emoji。它需要翻译成您选择的语言和 RegExp 库，并依赖于这些模式中的 Unicode 支持。

\p{RI} \p{RI} 
| \p{Emoji} 
  ( \p{EMod} 
  | \x{FE0F} \x{20E3}? 
  | [\x{E0020}-\x{E007E}]+ \x{E007F} )?
  (\x{200D} \p{Emoji}
    ( \p{EMod} 
    | \x{FE0F} \x{20E3}? 
    | [\x{E0020}-\x{E007E}]+ \x{E007F} )?
  )*

依靠这些字符属性，就不必维护自定义数据库或已知字符和组合表。 Unicode 规范更新应通过所提供的框架、语言或平台进行。
