I was instructed by the master yesterday
The test used
= =? : and if else () ()
xzyHe is the value of DropDownlist, which is 0 if it is empty
Another writing method:

xzyHe is the value of DropDownlist, which is 0 if it is empty
if (xzyHe ==""){int xzyHe==0;else{int xzyHe = DropDownlist.Text.Trim();}
Another writing method:
int xzyHe = ConVert.ToInt32(xzyHe == ""?0:int.Parse(DropDownlist.Text.Trim()));
