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. Eg:

regex.MatchReplace(text, match => "replacement string");

This way I can create my own logic for generating the replacement string which may involve invoking various methods etc. ie things you can't do with substitution patterns. Anyone know how I can accomplish this?

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

Please have a look at the following:

You can define an extension method for the RegEx class which will allow you to specify an Action<> as an argument.
