包装和解包

int变量可以用ToString方法隐式的转换为一个System.Object对象，这个过程叫包装；一个System.Object也可以转换为一个值变量，这个过程叫解包

1 using System;
2  using System.Collections.Generic;
3 using System.Linq;
4 using System.Text;
5
6 namespace ConsoleApplication2
7 {
8 class Program
9 {
10 static void Main(string[] args)
11 {
12 int myInt1 = 10;
13
14 //包装
15 Console.WriteLine("myInt1.ToString() = " + myInt1.ToString());
16 Console.WriteLine("myInt1.GetType() = " + myInt1.GetType());
17
18 int myInt2 = 10;
19 object myObject = myInt2;
20 Console.WriteLine("myInt2 =" + myInt2);
21 Console.WriteLine("myObject =" + Int2);
22
23 //解包
24
25 int myInt3 = (int)myObject;
26 Console.WriteLine("myInt3 = " + myInt3);
27 }
28 }
29 }
