When writing a program today, I accidentally forgot the conversion format, and the result is wrong, and I am wrong.
Similar to Messagebox.show ("" 1) .tostring ()); this code, the compiler actually does not report.
Interested friends may wish to try themselves. As for the reasons. I guess that there is Tostring () outside the brackets, which may be called to change to Tostring to each element in parentheses () .. only guess, hope masters Finger.
