RegExp selecting strings surrounded by brackets

Question

My purpouse is to select every character which is surrounded by { and }, this is easily achievable using this regexp {\w*}.

I've developed an extenstion method for strings:

    public static IEnumerable<string> ObtainTokens(this string originalString)
    {
        Regex expression = new Regex(@"{\w*}");
        foreach (Match element in expression.Matches(originalString))
        {
            //Exclude the brackets from the returned valued
            yield return Regex.Replace(element.Value, @"{*}*", "");
        }
    }

Is there a way to get rid of of Regex.Replace? Returning the values as IEnumerable is a good choice?

Modify your regexp: {(\w*)} and then replace:

yield return Regex.Replace(element.Value, @"{*}*", "");

with

yield return element.Groups[1].Value;

\$\begingroup\$ By applying your suggestion on the test string {THIS} is a {TEST} the response is an IEnumerable<string> containing two empty string. \$\endgroup\$
