1. 自动属性(Automatic Properties) 
相信C#开发者都曾遇到类似如下繁琐的get/set:
(重复性的机械劳动啊!我曾经为此而心烦不已,后来干脆在VS中安装一个叫VSProperty的插件)
    public class Person 
    {

        private string _trueName;
        private string _nickName;
        private int _age;
        
        public string TrueName 
        {
            get {
                return _trueName;
            }
            set {
                _trueName= value;
            }
        }

        public string NickName 
        {
            get {
                return _nickName;
            }
            set {
                _nickName= value;
            }
        }

        public int Age 
        {

            get {
                return _age;
            }
            set {
                _age = value;
            }
        }
    }

庆幸的是,在VS2008中有了改观,你可以这样了:
    public class Person
    {
        public string TrueName {    get; set;        }
        public string NickName {    get; set;        }
        public int Age {            get; set;        }
    }

2. 对象初始化器(Object Initializers):

之前初始化方式:
   Person person = new Person();
   person.TrueName = "Johson";
   person.NickName = "大可山";
   person.Age = 30;

现在你可以:
   Person person = new Person { TrueName="Johnson", NickName = "大可山", Age=30 }; //一行搞定,真是方便!

要加上通讯地址怎么办?
可以改成:
   Person person = new Person
   {
      TrueName = "Johnson",
      NickName = "大可山"
      Age = 30,
      Address = new Address {
         Street = "福田区深南大道6008号深圳报业集团",
         City = "深圳市",
         Province = "广东省",
         Zip = 518009
      }
   };
注意看Address也是新加的,直接new!

3.集合初始化器(Collection Initializers)
可以使用这样:
  List<Person> people = new List<Person>();
          
  people.Add( new Person { TrueName = "Johnson", NickName = "大可山", Age = 30 } );
  people.Add( new Person { TrueName = "Bill", NickName = "比尔大哥", Age = 40 } );
  people.Add( new Person { TrueName = "Jim", NickName = "小靓哥", Age = 20 } );

甚至可以这样:
List<Person> people = new List<Person> {
      new Person { TrueName = "Johnson", NickName = "大可山", Age = 30 },
      new Person { TrueName = "Bill", NickName = "比尔大哥", Age = 40 },
      new Person { TrueName = "Jim", NickName = "小靓哥", Age = 20 }
   };
(又少了几个Add)

一句话,越来越人性化了!
