Regex - Does not contain certain Characters

Question

I need a regex to match if anywhere in a sentence there is NOT either < or >.

If either < or > are in the string then it must return false.

I had a partial success with this but only if my < > are at the beginning or end:

(?!<|>).*$

I am using .Net if that makes a difference.

Thanks for the help.

Answer 1

^[^<>]+$

The caret in the character class ([^) means match anything but, so this means, beginning of string, then one or more of anything except < and >, then the end of the string.
