If the data is tokenized (i.e. "Dear $name$, as of $date$ your balance is $amount$"), then a Regex
can be useful:
static readonly Regex re = new Regex(@"$(w+)$", RegexOptions.Compiled);
static void Main() {
string input = @"Dear $name$, as of $date$ your balance is $amount$";
var args = new Dictionary<string, string>(
StringComparer.OrdinalIgnoreCase) {
{"name", "Mr Smith"},
{"date", "05 Aug 2009"},
{"amount", "GBP200"}
};
string output = re.Replace(input, match => args[match.Groups[1].Value]);
}
However, without something like this, I expect that your Replace
loop is probably about as much as you can do, without going to extreme lengths. If it isn't tokenized, perhaps profile it; is the Replace
actually a problem?
