三元最佳实践 [英] Ternary Best Practice

问题描述

我有一点code，虽然简单或许不能立即为它做什么显而易见的。

I have a bit of code, that while simple perhaps isn't immediately obvious as to what it does.

I found @(Model.Count() == 0 ? "no" : Model.Count().ToString()) @(Model.Count() == 1 ? "person" : "people")
@foreach (var item in Model) {
   <div>@item.Name at @item.Email</div>
}

和之前我写的很多code这样的，我想知道这是否是这样做的一个很好的方式。

And before I write lots of code like this, I wanted to know if this is a good way of doing this.

因此​​，问题是，在.NET中是有这样做的更好的框架的方法，或者是三元法细

Thus the question is, in .NET is there a better framework way of doing this, or is the Ternary method fine

在premise显然

• 0记录=我发现没有人
• 1纪录=我发现1人
• 2+记录=我发现2人

推荐答案

在我看来，这是精绝使用三元有条件的运营商这种状况。

In my opinion it is absolutely fine to use the Ternary conditional operator for this kind of condition.

有经验的开发人员了解它，而不考虑它，但如果你想，以方便阅读对于初学者来说，你也可以使用如果和其他结构。

Developers with experience understand it without thinking about it, but if you want to make it easy readable for beginners, you can also use an if and else construct.

不过，我会用任何（）作为@ I4V在注释中。

But I would use Any() as @I4V mentioned in the comment.

I found @(Model.Any() ? Model.Count().ToString() : "no") @(Model.Count() == 1 ? "person" : "people")


@foreach (var item in Model) {
   <div>@item.Name at @item.Email</div>
}
