use MatchEvaluator
public class MyData
{
string[] values = {"a","b","c","d","e","f","h","k","l"};
public string GetValue(Match m)
{
string n = m.Groups[1].Value;
return values[Convert.ToInt32(n)];
}
}
static void Test70()
{
string s = "bbs.aspx?ID={8}&TypeID={3}";
Regex re = new Regex(@"\{(\d+)\}");
MyData md = new MyData();
string s2 = re.Replace(s,new MatchEvaluator(md.GetValue));
Console.WriteLine(s2);

you don't need to use regular expressions, just use String.Format
dim s as string = "bbs.aspx?ID={0}&TypeID={1}"
dim s2 as string = String.Format(s,data(0),data(1))
dim s as string = "bbs.aspx?ID={0}&TypeID={1}"
dim s2 as string = String.Format(s,data(0),data(1))
