Regex - Does not contain certain Characters

Question

I need a regex to match if anywhere in a sentence there is NOT either  lt  or     If either  lt  or   are in the string then it must return false   I had a partial success with this but only if my  lt    are at the beginning or end       lt   gt        I am using  Net if that makes a difference   Thanks for the help

lt  gt       The caret in the character class      means match anything but  so this means  beginning of string  then one or more of anything except  lt  and  gt   then the end of the string

Here you go       lt  gt       This will test for string that has no  lt  and no  gt   If you want to test for a string that may have  lt  and  gt   but must also have something other you should use just     lt  gt    or       lt  gt         Where   lt  gt   means any of  lt  or  gt  and    lt  gt   means any that is not of  lt  or  gt    And of course the mandatory link
