哪个是在C#中使用的更好的"if语句"

Question

这两种方法都有效,但是使用以下方法的方法更好:

PlaceHolder PH = ctl.PlaceHoldNu == 1 ? (PlaceHolder)Page.Master.FindControl("PlaceHolder1") : (PlaceHolder)FindControl("PlaceHolder" + ctl.PlaceHoldNu);

要么

           PlaceHolder PH;
                    if (ctl.PlaceHoldNu == 1)
                        PH = (PlaceHolder)Page.Master.FindControl("PlaceHolder1");
                    else
                        PH = (PlaceHolder)FindControl("PlaceHolder" + ctl.PlaceHoldNu);

Answer 1

另一种解决方案是:

PlaceHolder PH = ctl.PlaceHoldNu == 1
    ? (PlaceHolder)Page.Master.FindControl("PlaceHolder1") 
    : (PlaceHolder)FindControl("PlaceHolder" + ctl.PlaceHoldNu);

此解决方案使用最少的行但保持可读性.
