在Razor中显示表达式值 [英] Display expression value in Razor

问题描述

我想在剃刀视图中将以下表达式的值显示为文本.

I want to display the value of the below expression as a text in razor view.

@(doc.Extension ?? string.Empty).ToUpperInvariant(); 

我尝试了所有变体，但似乎无济于事. 我知道我可以使用temp变量来存储此表达式的值，但是我想知道是否有一种方法可以内联.

I've tried every variant but nothing seems to work. I know i can use a temp variable to store the value of this expression but I was wondering if there was a way to do this inline.

@((doc.Extension ?? string.Empty).ToUpperInvariant();)
@{@:@(doc.Extension ?? string.Empty).ToUpperInvariant();} 

推荐答案

如果不使用分号，Razor会将代码解释为表达式而不是语句.例如:

If you don't use a semicolon, Razor will interpret your code as an expression instead of a statement. E.g.:

@((doc.Extension ?? string.Empty).ToUpperInvariant())
