I’m having trouble creating a Regex to match either a GUID or an error message from a response stream.

For example, the response is either:

{ "uuid": "8e5b0721-26c4-11df-b354-002170de47d3" }

or

{ "error": "<--Error Message-->" }

I have the Regex for a GUID:

new Regex(@"^(\{){0,1}[0-9a-fA-F]{8}\-[0-9a-fA-F]{4}\-[0-9a-fA-F]{4}\-[0-9a-fA-F]{4}\-[0-9a-fA-F]{12}(\}){0,1}$"

But I’m not entirely sure that the response will always be a GUID.

I guess I’m looking for a GUID that will return a the contents of the second set of quotation marks regardless of type.

This is a json format string.

Instead of using regex to get the data, use a json parer instead.
