string input = @"I have a line XX,VV,A01,A02,A03,A11,A12,A13,A14,B11,B12,B13,ZZ,DD
I need a regular expression for
If I find A01,A02,A03 or A11,A12,A13,A14 in my line, I have to replace with ""AA""
If I find B11,B12,B13 I have to replace with ""BB""
I have tried using
if (Regex.IsMatch(Value, ""^A0[2-9]"")|| Regex.IsMatch(Value, ""^A1[0-5]""))
It didnt work -- so basically if i have A02,A03, A04, A05, A06, A07 or A10,A11,A12....... A15 , I have to replace with ""AA""";
RegexOptions options = RegexOptions.Multiline | RegexOptions.IgnoreCase | RegexOptions.IgnorePatternWhitespace;
Regex regex = new Regex(pattern, options);
string result = regex.Replace(input, substitution);
}
