&是什么QUOT;计数++ QUOT;在C＃中返回？
问题描述：
恰好碰到了一些代码，这不是做什么，我想它应该。难道其他人认为这应该返回1？是否有一个很好的解释，为什么它不？
Just ran into a bit of code that wasn't doing what I thought it should. Do other people think this should return 1? Is there a good explanation as to why it doesn't??
int count = 0;
count++.ToString(); // Returns 1 no?
我一直以为计数++是一样的计算= + 1 ...
I always thought count++ was the same as count = count + 1...
答
X ++ 是后的增量运营商。这意味着，值 X 递增，但的 老的（非增量）x值返回（在你的情况下0，到的ToString 应用）
x++ is a post increment operator. It means that the value of x is incremented, but the old (non-incremented) value of x is returned (0 in your case, to which ToString is applied).
要搞定的。你想要的行为，使用的前的递增运算符 ++ X 。
To get the behavior you want, use the pre increment operator ++x.
