.net - Is StringBuilder.Replace() more efficient than String.Replace?

Question

If you have to use String.Replace() to replace test 50 times, you essentially have to create a new string 50 times. Does StringBuilder.Replace() do this more efficiently? E.g., should I use a StringBuilder if I'm going to be replacing a lot of text, even while I won't be appending any data to it?

I'm using .NET, but I assume this would be the same as Java and possibly other languages.

Answer 1

This is exactly the type of thing StringBuilder is for - repeated modification of the same text object - it's not just for repeated concatenation, though that appears to be what it's used for most commonly.
