Initialize properties in an object

For example, you have a class which looks like this:

class Customer
{
   public string account_code { get; set; }
   public string name { get; set; }
   public string email { get; set; }
}

This is what we used to do to initialize the properties in a new object:

   Customer c1 = new Customer();
   c1.account_code = "a001";
   c1.name = "ABC Ltd Co";
   c1.email = "info@abc.testing.com";

Starts from C# 3.0, you may initialize the properties in a new object instance in a single line of code which looks like this:

   Customer c2 = new Customer()
   { account_code = "a001", 
     name = "ABC Ltd Co", 
     email = "info@abc.testing.com" };
