find all word with apostrophe using regex

Question

I have a hard time solving this problem I need to get all the word that contains apostrophe, sometimes the single used as apostrophe

This is my regex:

[\u0027\u2019]

And this is my sample words:

'Chapert 2' 
Chapter's
chapters'

My expected output is

Chapter's
chapters'

But my code right now is it gets all the word that contains apostrophe or single qoute. How can i get all the word that doesn't start with apostrophe or single qoute?

This should give you the desired result:

Regex rgx = new Regex(@"^[^'].*'.*$");
List<string> list = new List<string>() { "'Chapert 2'", "Chapter's", "chapters'" };

foreach(var item in list)
{
    if (rgx.IsMatch(item))
        Console.WriteLine(item);
}

Breakdown

^ - Start of string.
[^'] - One character that is NOT the '.
.* - Zero or more any characters.
' - There has to be at leas one '
.* - Zero or more any characters again to end the string.
$ - End of string.

Thank you for the solution and details about the regex. I choose this answer because of the completeness. — Ramon bihon, Aug 02 '18 at 08:34

^[^'] is enough.

The first ^ matches the beginning of a string
[^…] matches every character except the ones inside brackets

So ^[^'] matches strings that start with a non-apostrophe character.

This won't work. Not only they shouldn't start with an apostrophe, OP also says that, _I need to get all the word that contains apostrophe_. – Sach Aug 02 '18 at 16:20
Alright, I'm embarrassed for my carelessness. I forgot what you said at the beginning. – Xiaofeng Zheng Aug 03 '18 at 04:29
