推荐答案
使用 休息
。
与您的问题无关,我在您的代码中看到以下行:
Unrelated to your question, I see in your code the line:
Violated = !(name.firstname == null) ? false : true;
在这一行中,您使用布尔值(name.firstname ==空)
。然后,对它应用!
运算符。然后,如果该值为true,则将Violated设置为false;否则,将其设置为false。否则为真。因此,基本上,将Violated设置为与原始表达式(name.firstname == null)
相同的值。为什么不使用它,如:
In this line, you take a boolean value (name.firstname == null)
. Then, you apply the !
operator to it. Then, if the value is true, you set Violated to false; otherwise to true. So basically, Violated is set to the same value as the original expression (name.firstname == null)
. Why not use that, as in:
Violated = (name.firstname == null);
