Regular expression: find spaces (tabs/space), but not newlines

How can I have a regular expression that tests for spaces or tabs, but not newlines?

I tried \s, but I found out that it tests for newlines too.

I use C# (.NET) and WPF, but it shouldn't matter.


Solution 1:

Use character classes: [ \t]

Solution 2:

Try this character set:

[ \t]

This does only match a space or a tabulator.
