Using Regex.Replace to keep characters that can be vary

Question

I have the following:

string text = \"version=\\\"1,0\\\"\";

I want to replace the comma for a dot, while keeping

Answer 1

You need a regex like this to locate the comma

Regex reg = new Regex("(version=\"[0-9]),([0-9]\")");

Then do the repacement:

text = reg.Replace(text, "$1.$2");

You can use $1, $2, etc. to refer to the matching groups in order.
