Answer 1

it really depends on what you need. Generally, if you need to concat strings, the best performance in runtime will be achieved by using StringBuilder. If you're referring in source code something like var str = "String1"+"String2" it will be converter into string str = "String1String2" on compilation. In this case you have no concatenation overhead
