单行如果有2个动作声明 [英] Single line if statement with 2 actions

问题描述

我想要做的单行if语句超过1行动

I'd like to do a single line if statement with more than 1 action.

默认是这样的：

(if) ? then : else

userType = (user.Type == 0) ? "Admin" : "User";

不过，我并不需要一个其他而已，我需要一个否则，如果

But I don't need an "else" only, I need an "else if"

一样，在​​多行：

if (user.Type == 0)
    userType = "Admin" 
else if (user.Type == 1)
    userType = "User"
else if (user.Type == 2)
    userType = "Employee"

有没有在单行的可能？

推荐答案

听起来像是你真的想要一个词典< INT，串> 也可能是开关语句...

Sounds like you really want a Dictionary<int, string> or possibly a switch statement...

您的 的可与运营商有条件做到这一点，但：

You can do it with the conditional operator though:

userType = user.Type == 0 ? "Admin"
         : user.Type == 1 ? "User"
         : user.Type == 2 ? "Employee"
         : "The default you didn't specify";

虽然你的可能的提出，在一条线，我强烈敦促你不要

While you could put that in one line, I'd strongly urge you not to.

我通常的只有的做到这一点不同的条件，虽然 - 不只是几个不同的可能值，这是更好的处理地图。

I would normally only do this for different conditions though - not just several different possible values, which is better handled in a map.
