Hi Folks , As per my earlier post on C# Orcas I am going to share my
experience on the various enhancements of C# 3.0 .Today I am going to talk
about implicity local variables . Implicitly typed local variable provides
the facility to declare the variable without specify the type , compiler will
implicitly declare the type of the variable based on the value initialize .To
declare the local variable use the keyword called var for example var
name= Hello MUGH;
// this is equals to
string name = Hello MUGH; //define a generic type
var myList = new List<int>();
myList.Add(100); Implicitly local variable makes our job very easy but it
work with few constraints like Implicitly type declaration must have
initialize to a value
// value must initialize
var x; // its a compile time error The initializer expression
cannot be the null type var x = null;
The initializer cannot be an object or collection initializer by itself, but
it can be a new expression that includes an object or collection initializer.
// collection initializer not allowed
var x = { 1, 2, 3}; // it can be declare as
var numbers = new int[] { 1, 2, 3};
Cheers
Anand
