1、索引器
1 class Player
2 {
3 private int[] arr = new int[100];
4 public int this[int index]
5 {
6 get {
7 if (index < 10 || index >= 10)
8 {
9 return 0;
10 }
11 else
12 {
13 return arr[index];
14 }
15 }
16 set {
17 if (!(index < 0 || index >= 100))
18 {
19 arr[index] = value;
20 }
21 }
22 }
23 }

1 class Program
2 {
3 static void Main(string[] args)
4 {
5 Player p = new Player();
6 p[0] = 100;
7 p[1] = 101;
8 Console.WriteLine(p[0]);
9 Console.ReadKey();

2、应用程序域
把一个程序进程分为各个独立的小进程，各个小进程中相互隔离，互不影响。
demo1
1 class Player
2 {
3 private static int i;
4 public void SetValue(int a)
5 {
6 i = a;
7 }
8 public int GetValue()
9 {
10 return i;
11 }
12 }
1 class Program
2 {
3 static void Main(string[] args)
4 {
5 Player p1 = new Player();
6 p1.SetValue(5);
7 Player p2 = new Player();
8 p2.SetValue(10);
9 Console.WriteLine(p1.GetValue());
10 Console.WriteLine(p2.GetValue());
11 Console.ReadKey();
12 }
13 }
demo2
1 public class Player:MarshalByRefObject
2 {
3 private static int i;
4 public void SetValue(int a)
5 {
6 i = a;
7 }
8 public int GetValue()
9 {
10 return i;
11 }
12 }
1 private void Form1_Load(object sender, EventArgs e)
2 {
3 AppDomain appDomain1 = AppDomain.CreateDomain("domain1");
4 Player play1 = (Player)appDomain1.CreateInstanceFromAndUnwrap("WindowsFormsApplication1.exe", "WindowsFormsApplication1.Player");
5 play1.SetValue(5);
6 AppDomain appDomain2 = AppDomain.CreateDomain("domain2");
7 Player play2 = (Player)appDomain2.CreateInstanceFromAndUnwrap("WindowsFormsApplication1.exe", "WindowsFormsApplication1.Player");
8 play2.SetValue(100);
9 MessageBox.Show(play1.GetValue().ToString());
10 MessageBox.Show(play2.GetValue().ToString());
11 }
3、CTS、CLS、CLR区别
cts:Comment Type System
通用系统类型，int32、int16--->int,String----->string,Boolean---->bool
不同语言变量类型不同，最后在.net上转换后都是同一种形式。
cls:Comment Language Specification 通用语言规范，不同语言语法不同，最后在.net上转换后都是同一种形式。
clr:Comment Language Runtime 公共语言运行时
