In C# code, I am trying to pass chinese characters: " 中文ABC123"
.
When I use alphanumeric in general using "^[a-zA-Z0-9\s]+$"
,
it doesn't pass for "中文ABC123"
and regex validation fails.
What other expressions do I need to add for C#?
To match any letter character from any language use:
\p{L}
If you also want to match numbers:
[\p{L}\p{Nd}]+
\p{L}
... matches a character of the unicode category letter.
it is the short form for [\p{Ll}\p{Lu}\p{Lt}\p{Lm}\p{Lo}]
\p{Ll}
... matches lowercase letters. (abc)
\p{Lu}
... matches uppercase letters. (ABC)
\p{Lt}
... matches titlecase letters.
\p{Lm}
... matches modifier letters.
\p{Lo}
... matches letters without case. (中文)
\p{Nd}
... matches a character of the unicode category decimal digit.
Just replace: ^[a-zA-Z0-9\s]+$
with ^[\p{L}0-9\s]+$
