Regex.Match Uppercase

Is there any way when using .net's Regex.Match() to work out if a string only contains capitals?

I am working in an application (so I don't have access to the code) which allows me to see if a field matches a certain regex pattern (using Regex.Match() behind the scene). So I want to use this to work out if the string is only capitals.

Thanks!

You can use the following regex. This will match any uppercase letter that has a lowercase variant.

^\p{Lu}+$

Or you can simply match only uppercase letter characters.

^[A-Z]+$

Use this as your match string for only capital letters and no special characters, including space.

^[A-Z]*$

To allow for special characters(only contains characters not lower case):

^[^a-z]*$
