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.

Negated Character Classes If you don't want a negated character class to match line breaks, you need to include the line break characters in the class. [^0-9\r\n] matches any character that is not a digit or a line break.
To match a character having special meaning in regex, you need to use a escape sequence prefix with a backslash ( \ ). E.g., \. matches "." ; regex \+ matches "+" ; and regex \( matches "(" . You also need to use regex \\ to match "\" (back-slash).
^[^<>]+$ 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.

Here you go:
^[^<>]*$
This will test for string that has no < and no >
If you want to test for a string that may have < and >, but must also have something other you should use just
[^<>] (or ^.*[^<>].*$)
Where [<>] means any of < or > and [^<>] means any that is not of < or >.
And of course the mandatory link.
