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, @"{*}*", "");


yield return element.Groups[1].Value;

ps: full code is avaialbe here

By applying your suggestion on the test string {THIS} is a {TEST} the response is an IEnumerable<string> containing two empty string. – Abaco Dec 13 '12 at 9:54
regex has beed updated to capture groups: {(\w*)} – Akim Dec 13 '12 at 10:16
