That's nice to know. Re the "for" loop, that's there intentionally and it's not part of what I wanted to measure... it's there to measure multiple times for a more accurate final result. If I didn't have the for loop, the operation would probably too fast to measure accurately. Flyswat: I have not looked at string.Format vs "+". I hope to experiment some and will post back here with the results. AJ.NET: Thanks for the info re string.Concat. That’s nice to know.

What about String.Format(”{0}{1}”,string1,string2);

If you write "string s= a + b + c;" the compiler will actually emit "string s= string.Concat(a,b,c);". It has to be one statement though, which is one reason why your sample loop didn't use it. Have a look at http://ajdotnet.wordpress.com/2007/05/20/about-the-virtue-of-not-improving-performance/ for details. Regarding the "stringbuilder in loop" example: There may be cases when you cannot avoid such code. It may however be improved by allocating the stringbuilder before the loop and reusing it.

It appears to be a better way to concatenate up to four dynamic strings than the "+" operator because it allocates memory for all the values in advance. I hope to shed some more light on string.Concat in a follow-up article. Lars: I didn’t even know about string.Concat before today.
