Optimizating Concatenation

[Mehyar]

Man. once you get in to the depth of optimizing code you get obsessed.

Anyone knows which is better to use,

String.Concat()
or
Simply the & operator
to concatinate strings...

 

[PlausiblyDamp]

For large strings using a StringBuilder rather than String.Concat or & operator.
As far as I'm aware the & and String.Concat compile down to the same instructions anyway.
