Question

Using type inference we can write:

var myList = new List<int>();

but it’s not really helping is it? Because the still requires us to only add ints, so wouldnt it have been easier to just declare the variable of ‘int’ instead of ‘var’ ?

Answer 1

The var doesn’t change the output of the compiler – it only makes the code shorter.

The only time that var offers anything else is in regards to anonymous types:

var foo = new { Bar = 123 };

It is important to understand that var doesn’t mean dynamic or variable (in the sense that it allows the type of the object to vary) – it just allows you to declare a variable and have the compiler infer the type as if you had declared it.
