嗯?如果真实)

问题描述

大家好，
我只是使用ReSharper重构一些旧代码，建议我更改此代码:

Hi All,
I''m just refactoring some old code using ReSharper and it''s suggested I change this:

var fileinfo = new FileInfo(file);
if(fileinfo != null)
{
}

对此:

to this:

var fileinfo = new FileInfo(file)
if(true)
{
}

我不确定我是否明白这一点，我现在有一个愚蠢的时刻，但这实际上在评估什么呢?缺少对对象的明确引用使我有些困惑.

谢谢，

Jammer

I''m not sure I get this, I''m having a stupid moment but what is this actually evaluating? The lack of explicit reference to an object has confused me a bit.

Thanks,

Jammer

推荐答案

var fileinfo = FileInfo.CreateNew(file);

1. if (true)真是愚蠢.
2. 如果某天某人会在两行之间插入fileinfo=null;怎么办?

1. if (true) is pretty silly.
2. What if some day, someone will insert fileinfo=null; between the two lines?

:)
