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.
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.
