ASP.NET MVC Razor:三元 [英] ASP.NET MVC Razor: Ternary

问题描述

在 Razor 视图引擎中使用三元时遇到了一些麻烦.

Having a little bit of trouble figuring out using a ternary with Razor view engine.

我的模型有一个字符串属性.如果该字符串属性为空，我想在视图中呈现 null.如果属性不为空，我希望它使用前导和尾随 ' 呈现属性值.

My model has a string property. If that string property is null, I want to render null in the view. If the property is not null, I want it to render the property value with a leading and trailing '.

我该怎么做?

更新:抱歉，稍微改变了问题.

UPDATE: Sorry, changed question slightly.

推荐答案

您应该能够像标题建议的那样使用三元运算符:

You should just be able to use a ternary operator like the title suggests:

@(string.IsNullOrEmpty(Model.Prop) ? "null" : "'" + Model.Prop + "'")
