Solution 1

An empty Guid is always the same value: 00000000-0000-0000-0000-000000000000
So the Regex would be trivial:

00000000-0000-0000-0000-000000000000

Why do I get the feeling this is not the question you meant to ask?

Solution 2

try this:

C#

public static bool IsGUID(string expression)
{
    if (expression != null)
    {
        Regex guidRegEx = 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})$");

        return guidRegEx.IsMatch(expression);
    }
    return false;
}
