C# 3.0对象和集合初始化怎么实现

这篇文章主要讲解了"C# 3.0对象和集合初始化怎么实现"，文中的讲解内容简单清晰，易于学习与理解，下面请大家跟着小编的思路慢慢深入，一起来研究和学习"C# 3.0对象和集合初始化怎么实现"吧！

Point类

public class Point  {      public int X { get; set; }      public int Y { get; set; }  }

对象类初始化可以这样定义了

Point p = new Point { X = 3, Y = 99 };

如果是集合初始化，主要继承了System.Collections.Generic.IEnumerable< T> ，并且有个公共方法Add可以进行初始化集合初始化

集合初始化例子具体如下

List< Point> Square = new List< Point>          {              new Point { X=0, Y=5 },              new Point { X=5, Y=5 },              new Point { X=5, Y=0 },              new Point { X=0, Y=0 }          };

完整的例子源码

class Program      {          static List< Customer> CreateCustomers()          {           return new List< Customer>          {              new Customer(1) { Name = "Alex Roland",      City = "Berlin"        },              new Customer(2) { Name = "Oliver Cox",       City = "Marseille"     },              new Customer(3) { Name = "Maurice Taylor",   City = "London"        },              new Customer(4) { Name = "Phil Gibbins",     City = "London"        },              new Customer(5) { Name = "Tony Madigan",     City = "Torino"        },              new Customer(6) { Name = "Elizabeth A. Andersen", City = "Portland" },              new Customer(7) { Name = "Justin Thorp",  City = "London"       },              new Customer(8) { Name = "Bryn Paul Dunton",  City = "Portland"     }          };        }           static void Main(string[] args)          {              List< Customer> customers = CreateCustomers();               Console.WriteLine("Customers:\n");              foreach (Customer c in customers)                  Console.WriteLine(c);          }
