What's the use/meaning of the @ character in variable names in C#?

I was doing some .net development and I noticed I could add an @ symbol before any method call, i.e.:

var message = dog.@SayHello();

Just wondering, why is the reason this can be done ??

Answer 1

The @ symbol can escape keywords and turn them into ordinary identifiers. Most .net languages support a mechanism like this since keywords are language dependent, and thus code written in other languages might collide with a keyword in your language without even noticing it.

Some people like using @this for the first parameter extension methods.

public static void MyExtension(this MyType @this)

another scenario where this can be useful is when using members to represent html attributes. Then without this feature you could not represent the class attribute.
