导读：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. 他们中的大多数似乎被发现,但有些则没有. 这是一个参考列表,以帮助：http://unicode.org/emoji/

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.

他们中的大多数似乎被发现,但有些则没有.

这是一个参考列表,以帮助：http://unicode.org/emoji/charts/full-emoji-list.html

所有的笑脸似乎都很好,但这些特定的表情符号并没有被正则表达式所抓住：

1920 U2614?伞与雨滴

1921年U26F1?伞在地上

1922年U26A1?高压

1923年U 2744?雪花

在键盘上这些并不是彼此靠近,但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,并且它不是真正的验证.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.

我不能只是去全ASCII,因为我需要人们输入像西里尔字母这样的字符,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,这对我来说非常困惑,我认为一些正确的方向推进将会有很长的路要走.

非常感谢您的宝贵时间：)

解决方法

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：

请参阅regex demo(尽管使用了JS选项,正则表达式在C#中产生相同的结果.)

该模式是从表情符号列表中动态创建的,并使用正则表达式进行收缩,并通过几个后处理步骤进一步缩小模式.
