'var' keyword in c#

Answer 1

Sure, just check one of the many links here : http://stackoverflow.com/search?q=c%23+var+keytword ;)

Answer 2

You can use the var keyword to infer the type of an object.

For example:

//without using the "var" keyword
Dictionary<List<string>,int> myCustomDictionary = new Dictionary<List<string>, int>();

//with the "var" keyword
var myCustomDictionary = new Dictionary<List<string>, int>();

Which is easier to read? :)
