How can I edit particular word one by one in a text line?

Question

Let's say I have a text:

"His name is Jack. Jack likes to ride a bike"

What method would you recommend using to edit word "Jack" one by one, for example, I want to make specific changes for each "Jack". I've tried using Remove() and Replace(), but these methods edit all "Jack" in the text.

The Regex.Replace(String, MatchEvaluator) may be what you need. In the specified input string, it replaces all strings that match a specified regular expression with a string returned by a MatchEvaluator delegate.
So your MatchEvaluator delegate can decide what to replace every single "Jack" with.
For example:

string s = "His name is Jack. Jack likes to ride a bike";
int count = 0;
string s2 = Regex.Replace(s, "Jack", match => {
    count++;
    return count > 1 ? "Jack2" : "Jack1";
});

s2 is:

His name is Jack1. Jack2 likes to ride a bike
