ASP.NET MVC Razor中新的空条件运算符 [英] The new null-conditional operator in ASP.NET MVC Razor

问题描述

因此，自从C#6.0发布以来，我就一直在使用null条件运算符.示例:

So since C# 6.0 came out, I've been using the null-conditional operator quite a lot. Example:

Model?.Person?.Zip

但是，现在我遇到的情况是，我有一个解决方案，客户在视图中对域模型进行操作.虽然我会用斧头追捕开发人员，但发现在视图中进行一些空检查会更容易.

However, I now have a situation where I have a solution where the customer operates on domain models in the view. While I would hunt down the developer with an axe, I find it easier to just do some null checks in the view.

但是，当我在Razor中进行此操作时:

However, when I go this in Razor:

@Model?.Person?.Zip

我的Model?被视为动态的，但?破坏了动态的事物，其余的则呈现为文本.

My Model? is seen as dynamic, but ? breaks the dynamic things and rest is rendered as text.

您如何解决这个问题?

推荐答案

只是一个猜测

@(Model?.Person?.Zip)
