I have a regular expresion like:

@"^[A-Z][a-z\-\'] ((\s[A-Z][a-z\-\'\.]*)?) (\s[A-Z][a-z\-\'\.]*)?"

which allows a name to be written like Name, Name LastName or Name LastName LastName. I added the special characters ', -,. for special names. But i want to add the condition that after the '-' the letter could be capital. But only after the dash. Nowhere else in the word, execptin the beggining. Any ideas?

CodePudding user response：

This regex would meet your dash criteria, although I can't speak for other naming variations that might be prevented.

^(?:[“"]?[A-Za-z][a-z]*["”'.,]?(-[A-Z][a-z] )?(?: (?!$))?) $

It matches the following:

Leonardo da Vinci
