Why use dynamic typing in c#?

Question

At first I thought something like:

var aName=getAllSomethings();

Is very unreadable, and so I\'ll use dynamic typing just when there\'s

Answer 1

As everyone else has mentioned, the 'var' keyword does not give us dynamic typing. The type is inferred at compile time.

I use var when I think it makes sense; namely, when the type is obvious and it cuts down on the verbosity of a declaration:

var someDict = new Dictionary();

Instead of...

Dictionary() someDict = new Dictionary();

However, in your example here:

var aName=getAllSomethings();

I wouldn't use 'var' because, as you have noticed already, you then have to check the return type of 'getAllSomethings()' (bad naming style for C# BTW) in order to know what 'aName' is, which just makes the code less readable.
