Note

Strictly speaking,

var

is not a C# keyword. It is permissible to declare variables, parameters, and fields

named “var” without compile-time errors. However, when the 

var

token is used as a data type, it is contextually

treated as a keyword by the compiler. For simplicity, I will use the term “

var

keyword,” rather than the more cum-

bersome “contextual 

var

token.”

In this case, the compiler is able to infer that myInt is in fact a System.Int32, myBool is a

System.Boolean, and myString is indeed of type System.String, given the initially assigned value.

You can verify this by printing out the type name via reflection:

static void DeclareImplicitVars()

{
