Yes. And String.Empty, but please don't worry about it.
The difference between String.Empty and “” are pretty small, but there is a
difference. “” actually creates an
object, it will likely be pulled out of the string intern pool and String.Empty creates no object, so if you are really looking for ultimate
memory efficiency, I suggest String.Empty.
However, you should keep in mind the difference is so trival you will
like never see it in your code…
