如何使MonoDevelop从C#6.0中识别nameof语法? [英] How do I make MonoDevelop recognize nameof syntax from C# 6.0?

问题描述

我正在使用MonoDevelop v5.9.6.尽管它似乎支持C#6.0，但该编辑器无法识别nameof关键字，并且将其标记为红色，因为它试图将其识别为标识符.

I'm in MonoDevelop v5.9.6. Although it seems to support C# 6.0, the editor doesn't recognize the nameof keyword, and it marks it red, because it tries to recognize it as if it were an identifier.

在没有以某种方式破坏编译的情况下，我可以使用任何技巧使它在编辑器中工作吗?

Is there any hack I can use to make it work in the editor, without breaking the compilation somehow?

推荐答案

此技巧有效:

// hack to make MonoDevelop recognize nameof syntax from C#6.0
using nameof = System.Func<string>;

编辑器将其识别为返回字符串"，并且与参数一起使用时不会出现任何错误，例如nameof(object.Equals).

The editor recognizes it as "returning a string" and doesn't give any errors when used with an argument, like, for instance nameof(object.Equals).

当我 Ctrl + Shift + Space 显示调用的签名时，VSCode会忽略它，而MonoDevelop会显示以下内容:

When I Ctrl+Shift+Space to show the signature of the call, VSCode ignores it, and MonoDevelop shows this:

VSCode(支持nameof语法)也没有抱怨.词法分析器将nameof识别为关键字(红色)，但是当我将鼠标悬停时将其识别为委托.
无论如何我都不会出错.

VSCode (which supports the nameof syntax) doesn't complain about it either. The lexer recognizes the nameof as a keyword (in red) but identifies it as a delegate when I hover.
In any case I don't get any errors.

更令人着迷的是，编译器(Mono和VS)只是忽略了using指令，还接受了nameof的用法，该用法正常工作.

What is even more intriguing, the compilers (both Mono and VS) simply ignore the using instruction and also accept usages of nameof, which works normally.

现在，后续问题将会是...为什么?编译器为什么不抱怨呢?

Now, the followup question would be... why though? Why won't the compilers complain about it?
