Regex to match words

I'm looking for a Regex (using .NET) to match the word ass. The Reg开发者_如何学运维ex shouldn't match words like assignment.

How can I do this?

You are looking for word boundaries (\b):

\bass\b

This will match ass but not bass or assignment.

How about \bass\b ? This uses word boundaries to limit it to the single word.

Visit this page for full manual Word Boundaries

Most modern regular expression engines support the \b anchor, meaning a zero-width word boundary.

See this page for some examples using that (and other) anchor characters.

Will this work for you?

\bass\b

\b(ass)\b or \bass\b should be good.
