在 C# 中的 if 语句中测试多个值 [英] Test for multiple values in an if statement in C#

问题描述

是否有 C# 中的速记语法来实现这一点:

Is there a shorthand syntax in C# to make this:

if ((x == 1) || (x==2) || (x==5) || (x==13) || (x==14))

...更短?类似(假设)

... shorter? Something like (hypothetically)

if (x in {1, 2, 5, 13, 14})

我感觉"它存在，我只是在精神上和谷歌上表现不佳.实际上，我必须经常测试一堆枚举，而且它只是不可读.如果语言已经支持它，我也讨厌创建一个小辅助函数.

I "feel" like it exists, I'm just coming up short mentally and Googly. In reality I have to test a bunch of enums frequently and it's just unreadable. I also hate to make a little helper function if the language supports it already.

提前致谢！

编辑

有一些涉及列表的巧妙解决方案……但我希望有某种纯粹的逻辑结构.如果它不存在，那就这样吧.谢谢！

There are clever solutions involving lists... but I was hoping for a pure logical construct of some kind. If it doesn't exist, so be it. Thanks!

推荐答案

试试这个:

if ((new[]{1, 2, 5, 13, 14}).Contains(x)) ...
