@ Operator on variable of type Func

Question

So I was digging through some code and I saw something along these lines.

Func<T> @delegate = ...

My question is what is the @ operator used for in this case?

I've seen it used when creating string literals but never when referencing something other than a string.

`delegate` is a **key word**, you can't put `Func delegate =` — Dmitry Bychenko, Sep 04 '15 at 14:35
Well whomever wrote this line of code did and it compiles just fine. — DotNetRussell, Sep 04 '15 at 14:36
Ohhh you're saying the @ symbol makes it a valid variable name.... Who the hell would do this.... — DotNetRussell, Sep 04 '15 at 14:37
@AnthonyRussell Sometimes a descriptive variable name happens to coincide with a language keyword. It's nice that the language provides a way to escape the keywords into usable identifiers. — Kyle, Sep 04 '15 at 15:24

Func<T> is a generic delegate in C#.

delegate is a reserved word in C# so the developer prefixed it with @ to use it as a valid variable name.

You will see it in asp.net MVC project for HTML helpers where for setting class we use @class as class is a reserved word in C# so we can't have a variable with name class
