问题描述
我的问题可能听起来有点愚蠢,但每次我面对它时都会让我烦恼.有什么区别:
My question might sound a little foolish but it bugs me every time i face it. What is the difference between :
where value.HasValue
和
where value != null
HasValue 是否检查 value 是否为空?
Does HasValue checks if value is null?
推荐答案
他们都做同样的事情,只是选择一个并坚持下去,这样你就有了一致性.最终两者都没有得到任何好处.
They both do the same thing, just pick one and stick with it so that you have consistency. There is nothing to gain by using either in the end.
