Emacs: how to select all text in double-quotes automatically from current focused position?

emacs

Solution

If you're one to work with the mouse, double-clicking selects text including the double-quotes.

expand-region allows you to select expanding lexical units of text one of the stopping points is string without quotes, and the one after that is string including quotes.

Problem

After search for a long time, I refer to here. if current position is between 2 double-quotes, is there any command can mark all text in the 2 double-quotes?
