和FirstOrDefault(func)&之间的区别哪里(func).FirstOrDefault()? [英] And difference between FirstOrDefault(func) & Where(func).FirstOrDefault()?

问题描述

 DataFeedManager.LoadAllDataFeeds().FirstOrDefault(d => d.ItemID == itemId);

和

DataFeedManager.LoadAllDataFeeds().Where(d=>d.ItemID = itemId).FirstOrDefault();

是否有特定的原因要优先于另一个?

Is there a particular reason to prefer one over the other?

推荐答案

为简洁起见，请优先选择第一个.

Prefer the first for brevity if you're comfortable with it.

如果您对可用的各种重载不太熟悉，请优先选择第二个.

Prefer the second for clarity if you're not as familiar with the various overloads available.

(当然，"you"实际上是每个人都在处理代码".)

(Where "you" is really "everyone working on the code" of course.)
