在C#中,\ p {Han}匹配中文字符和日文平假名和片假名。我想区分它们,所以我该怎么办?将每个char转换为unicode,然后检测该字符是否在范围内?
答案 0 :(得分:1)
//For chinese chars
public bool IsChinese(string text)
{
return text.Any(c => c >= 0x20000 && c <= 0xFA2D);
}
//For japanese chars
private static IEnumerable<char> GetCharsInRange(string text, int min, int max)
{
return text.Where(e => e >= min && e <= max);
}
用法:
var romaji = GetCharsInRange(searchKeyword, 0x0020, 0x007E);
var hiragana = GetCharsInRange(searchKeyword, 0x3040, 0x309F);
var katakana = GetCharsInRange(searchKeyword, 0x30A0, 0x30FF);
var kanji = GetCharsInRange(searchKeyword, 0x4E00, 0x9FBF);
