本文对比了C# 2.0与3.0中对象初始化语法的不同，展示了如何更简洁地创建和初始化对象。通过具体的代码示例，介绍了列表初始化及单个对象属性设置的变化。

 List<Customer> customers = new List<Customer>

            {

              new Customer { Id = 1, Name="Dave", City="Sarasota" },

              new Customer { Id = 2, Name="John", City="Tampa" },

              new Customer { Id = 3, Name="Abe", City="Miami" }

            };

而在2.0时代,我们为列表对象赋值要这样写:

            List<Customer> customers2 = new List<Customer>();

            customers2.Add(new Customer { Id = 1, Name = "Dave", City = "Sarasota" });

            customers2.Add(new Customer { Id = 2, Name = "John", City = "Tampa" });

            customers2.Add(new Customer { Id = 3, Name = "Abe", City = "Miami" });

而在对象单个实体赋值时也就方便了,而且可读性也强了

2.0时代:          

Customer customer = new Customer();

            customer.Id = 1;

            customer.Name = "zzl";

            customer.City = "beijing";

 

 3.0时代     

           Customer customer2 = new Customer

            {

                Id = 1,

                Name = "zzl",

                City = "beijing"

            };
