任何人发现使用" VAR"比LINQ其他？ [英] Anyone found a use of "var" other than for LINQ?

问题描述

只是好奇。 ？我约99.999％肯定是没有的......但什么

Just curious. I'm about 99.999% sure there is none...but anything?

编辑：这些都是OK的回答（节省打字时间或使代码为可读性更简洁）。我想我应该澄清我的意思是用 - 一些结构/设计，不能没有VAR来完成。

These are OK answers (saving typing time or making the code less verbose for "readability"). I guess I should have clarified what I meant by "use" - some construct/design that couldn't be done without "var" .

推荐答案

请告诉我更好的可读性方面？

Whats better in terms of readability?

AReallyReallyLongBusinessObjectName obj = new AReallyReallyLongBusinessObjectName();

或

var obj = new AReallyReallyLongBusinessObjectName();

我说，在可读性方面，因为使用VAR绝对没有看到，因为这两种说法对你的应用程序的影响。编译时会产生相同的IL

I say in terms of readability because using var has absolutely no impact on your app seeing as the two statements generate the same IL when compiled.

响应编辑：有什么要求您使用VAR（除匿名类型） - 其只是语法糖。

Response to edit: there is nothing that requires you to use var (other than anon types) - its just syntactic sugar.
