Regular Expression Question...

[Guest]

I am not sure if this is the correct forum to post this question so I thought
I would start here.

Is there any way to generate a new string (conditionally) based on an input
string and a regular expression?. Is there any method (such as Replace) of
the RegEx object that will do this?

For example...

string s1;
string s2;
string s3;

s1 = "^(?<dd>\\d{2, 2})$";
s2 = "YEAR : ${dd}";
s3 = RegEx.Replace("06", s1, s2");

The variable s3 now has the value "YEAR : 06". I would somehow like the
variable s3 to have the value "YEAR : 2006" (or the value "YEAR : 1980" if
the value of the first parameter was "80") using only the code above. The
criteria for prefixing the input with either "19" or "20" would depend on
whether he input was less than or equal to 60.

Thank you,

Check out the following overload of the Regex.Replace method. It takes a
MatchEvaluator delegate method parameter, which allows you to perform custom
logic in the replacement:
