Lambda变量名称-简称还是不简称? [英] Lambda variable names - to short name, or not to short name?

问题描述

通常，当我使用lambdas时，我只使用"a，b，c，d ..."作为变量名，因为可以轻松推断类型，并且我发现短名称更易于阅读.这是一个示例:

Typically, when I use lambdas, I just use "a, b, c, d..." as variable names as the types are easily inferred, and I find short names to be easier to read. Here is an example:

var someEnumerable = GetSomeEnumerable();
var somethingElseList = someEnumerable.Select(a => a.SomeProperty)
                                      .OrderBy(a => a.SomePropertyField);
var someDictionary = somethingElseList.ToDictionary(a => new SomeClass(a.Prop1),
                                                    a => a);

对此命名有些疑问，并且希望看到长键入的名称，如下所示:

Some question this naming, and would prefer to see long typed out names, like this:

var someEnumerable = GetSomeEnumerable();
var somethingElseList = someEnumerable.Select(importantObj => importantObj.SomeProperty)
                                      .OrderBy(objsInfo => objsInfo.SomePropertyField);
var someDictionary = somethingElseList.ToDictionary(theInfoId => new SomeClass(theInfoId.Prop1),
                                                    theInfoId2 => theInfoId2);

由于范围非常狭窄(在括号之间)，除非您变​​得愚蠢并嵌套它们，否则我发现更容易读取短名称.

Since the scope is so narrow (between the parens), unless you're getting stupid and nesting them, I find it easier to read short names.

在不陷入我上面使用的愚蠢命名示例的情况下，关于Lambda变量名称的一般共识是什么?是短名还是短名?

Without getting caught up in the silly naming examples I used above, what is the general consensus on Lambda variable names? To short name, or not to short name?

推荐答案

我通常采用的方式取决于您要枚举的集合.如果集合的名称暗示了lambda参数的类型，那么我只使用单个字母，但是，如果集合的描述性不强，那么我将使用一个单词.

The way I usualy do it depends on the collection you're enumerating over. If the name of the collection implies what type the lambda parameter will be, then I just go with the single letter, however if the collection isn't as descriptive, then I'll use a word.

IE:

myCollection.Where(person =>....); //non descriptive collection name

myPeopleCollection.Where(p=>...); // descriptive collection name
