Ask how to use c # for grammar or other optimization the following code

 
Int iWTian=0;//(per week) on the day of the library value time less than now -- on the 
If (the Convert. ToDateTime (DateTime. Now. ToString (wTime)) & lt;=a DateTime. Now) {iWTian=7; }//on the 1 week 

Int iWeek=the Convert. ToInt32 (DateTime. Today. DayOfWeek. ToString (" d "));//the current week, week number formatting 0 to 6 
Int iTian=0;//increase the number of days
