Replacing Regex matches using lambda expression

Question

I\'m looking for a simple regex find and replace solution were I can just provide a lambda expression for replacing each matches. E.g:

regex.MatchReplace(tex         


        

Answer 1

Regex already has one. For ex,

string input="abc123def";
var output = Regex.Replace(input, @"\d", m=>(m.Value[0]-'0'+ 5).ToString());
Console.WriteLine(output);

OUTPUT: abc678def
