Regular Expression for Alphabetic Letter with accent

问题

I need a validation a texbox in c# and asp.net using Regular Expression.

I need allow:

• alphabetic letters UPPERCASE and lowercase or any ComBINAtion
• accented letters like: èèéàù ...
• numbers
• only one white space " "

I need dot NOT allow:

• any special characters like: |!"£$%&/()<> ...

Any ideas? Thanks for your help

回答1:

If validation occurs at server side, you can use the pattern:

^\w*(\s\w*)?$

\w in .Net is Unicode aware - it should include all letters.

Note that \w also include the underscore and other word-connectors. You can use [\p{L}\p{Nd}] instead of \w to disallow them.

This might be a start

^([\w\d]+[ ]?)+$

\d matches the digits

\w matches "word characters". The.NET RegEx considers unicode characters as word characters. See: http://regexlib.com/CheatSheet.aspx

I'm not sure what you mean by "one white space". This expressions allows one space, but not double-spaces, between words.
