這篇文章主要講解了“C# 3.0對(duì)象和集合初始化怎么實(shí)現(xiàn)”,文中的講解內(nèi)容簡(jiǎn)單清晰,易于學(xué)習(xí)與理解,下面請(qǐng)大家跟著小編的思路慢慢深入,一起來(lái)研究和學(xué)習(xí)“C# 3.0對(duì)象和集合初始化怎么實(shí)現(xiàn)”吧!
Point類(lèi)
public class Point { public int X { get; set; } public int Y { get; set; } }
對(duì)象類(lèi)初始化可以這樣定義了
Point p = new Point { X = 3, Y = 99 };
如果是集合初始化,主要繼承了System.Collections.Generic.IEnumerable< T> ,并且有個(gè)公共方法Add可以進(jìn)行初始化集合初始化
集合初始化例子具體如下
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 } };
完整的例子源碼
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); }
