var keyword runtime or compile time?

Question

var keyword gets the type at the runtime or compile time?

or depends?

Answer 1

Plain and simple: compile time

var isn't a type. The actual type is figured out at compile-time.

var variables are also known as Implicitly Typed Local Variables (C# Programming Guide)

Answer 2

var type gets at compile time .

Var is an implicitly typed local variable is strongly typed just as if you had declared the type yourself, but the compiler determines the type

var i = 10; // implicitly typed
int i = 10; //explicitly typed

Answer 3

The var keyword is implicitly typed. This means that it is strongly typed, but the compiler determines the type.
