Using var or not using var [duplicate]

Answer 1

It is subjective, but I don't like using vars. As for me they don't improve readability.

But general guideline on var usage is following:

Use var when it is absolutely clear what type of the variable is being declared:

Dictionary> varOfSomeLongType = new Dictionary>();

or when you are declaring variable of anonymous type:

var linqResult = from element in SomeCollection
                 select new { element.A, element.B }
