Answer 1

when using Marc Gravell's RegEx solution, first check if a token is available using i.e. ContainsKey, this to prevent KeyNotFoundException errors :

string output = re.Replace(zpl, match => { return args.ContainsKey(match.Groups[1].Value) ? arg[match.Groups[1].Value] : match.Value; });

when using the following slightly modified sample code (1st parameter has different name):

    var args = new Dictionary(
        StringComparer.OrdinalIgnoreCase) 
        {
            {"nameWRONG", "Mr Smith"},
            {"date", "05 Aug 2009"},
            {"AMOUNT", "GBP200"}
        };

this produces the following:

"Dear $name$, as of 05 Aug 2009 your balance is GBP200"
