Difference between “var” and “object” in C# [duplicate]

by

Beginning in Visual C# 3.0, variables that are declared at method scope can have an implicit type var. An implicitly typed local variable is strongly typed just as if you had declared the type yourself, but the compiler determines the type. The following two declarations of i are functionally equivalent:

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

var isn’t object

You should definitely read this : C# 3.0 – Var Isn’t Object
