c# - Replace Multiple References of a pattern with Regex -

i have string in following form

$kl\u#, $as\gehaeuse#, $kl\tol_plus#, $kl\tol_minus# 

basically string made of following parts

• $ = delimiter start
• (some text)
• # = delimiter end
• (all of n times)

i replace each of these sections meaningful text. therefore need extract these sections, based on text inside each section , replace section result. resulting string should this:

12v, 0603, +20%, -20% 

the commas , else not contained within section stays is, sections replaced meaningful values.

for question: can me regex pattern finds out these sections can replace them?

you need use regex.replace method , use matchevaluator delegate decide replacement value should be.

the pattern need can $ except #, #. put middle bit in brackets stored separate group in result.

\$([^#]+)# 

the full thing can (up correct appropriate replacement logic):

string value = @"$kl\u#, $as\gehaeuse#, $kl\tol_plus#, $kl\tol_minus#";  string result = regex.replace(value, @"\$([^#]+)#", m => {     // method takes matching value , needs return correct replacement     // m.value e.g. "$kl\u#", m.groups[1].value bit in ()s between $ , #     switch (m.groups[1].value)     {         case @"kl\u":             return "12v";         case @"as\gehaeuse":             return "0603";         case @"kl\tol_plus":             return "+20%";         case @"kl\tol_minus":             return "-20%";         default:             return m.groups[1].value;     } });
