Thread.SetData与ThreadStatic

今天在这里看到一篇关于Thread.SetData的文章,忽然想起了ThreadStatic特性一样可使变量线程唯一,于是修改了一下代码测试下:
 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Text;
 5 using System.Threading;
 6 
 7 namespace ThreadSetDataTest
 8 {
 9     class Program
10     {
11         static void Main(string[] args)
12         {
13             Thread[] t = new Thread[4];
14             for (int i = 0; i < t.Length; i++)
15             {
16                 t[i] = new Thread( new ThreadStart(Slot.SlotTest));
17                 t[i].Start();
18             }
19         }
20     }
21 
22     class Slot
23     {
24         static Random randomGenerator = new Random();
25 
26         [ThreadStatic]
27         public static int threadStaticData;
28 
29         public static void SlotTest()
30         {
31             Thread.SetData(Thread.GetNamedDataSlot("Random"), randomGenerator.Next(0, 200));
32             threadStaticData = randomGenerator.Next(10, 100);
33 
34             Console.WriteLine("Data is Thread_{0}'s data solt :{1,3}, ThreadStatic Data is {2}",
35                 AppDomain.GetCurrentThreadId(),
36                 Thread.GetData(Thread.GetNamedDataSlot("Random")).ToString(), threadStaticData);
37 
38             Thread.Sleep(1000);
39 
40             Console.WriteLine("Data is Thread_{0}'s data solt :{1,3},ThreadStatic Data is {2}",
41                 AppDomain.GetCurrentThreadId(),
42                 Thread.GetData(Thread.GetNamedDataSlot("Random")).ToString(), threadStaticData);
43 
44             Thread.Sleep(1000);
45 
46             Other o = new Other();
47             o.ShowSoltData();
48         }
49 
50     }
51 
52     class Other
53     {
54         public void ShowSoltData()
55         {
56             Console.WriteLine("Data is Thread_{0}'s data solt :{1,3},ThreadStatic Data is {2}",
57                AppDomain.GetCurrentThreadId(),
58                Thread.GetData(Thread.GetNamedDataSlot("Random")).ToString(), Slot.threadStaticData);
59         }
60     }

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Text;
 5 using System.Threading;
 6 
 7 namespace ThreadSetDataTest
 8 {
 9     class Program
     {
         static void Main(string[] args)
         {
             Thread[] t = new Thread[4];
             for (int i = 0; i < t.Length; i++)
             {
                 t[i] = new Thread( new ThreadStart(Slot.SlotTest));
                 t[i].Start();
             }
         }
     }
 
     class Slot
     {
         static Random randomGenerator = new Random();
 
         /// <summary>
         /// 线程唯一的变量
         /// </summary>
         [ThreadStatic]
         public static int threadStaticData;
 
         public static void SlotTest()
         {
             // 在每条线程中设置随机的值
             Thread.SetData(Thread.GetNamedDataSlot("Random"), randomGenerator.Next(0, 200));
 
             // 同样在每条线程中设置随机的值
             threadStaticData = randomGenerator.Next(10, 100);
 
             Console.WriteLine("Data is Thread_{0}'s data solt :{1,3}, ThreadStatic Data is {2}",
                 AppDomain.GetCurrentThreadId(),
                 Thread.GetData(Thread.GetNamedDataSlot("Random")).ToString(), threadStaticData);
 
             Thread.Sleep(1000);
 
             Console.WriteLine("Data is Thread_{0}'s data solt :{1,3},ThreadStatic Data is {2}",
                 AppDomain.GetCurrentThreadId(),
                 Thread.GetData(Thread.GetNamedDataSlot("Random")).ToString(), threadStaticData);
 
             Thread.Sleep(1000);
 
             Other o = new Other();
             o.ShowSoltData();
         }
 
     }
 
     class Other
     {
         public void ShowSoltData()
         {
             Console.WriteLine("Data is Thread_{0}'s data solt :{1,3},ThreadStatic Data is {2}",
                AppDomain.GetCurrentThreadId(),
                Thread.GetData(Thread.GetNamedDataSlot("Random")).ToString(), Slot.threadStaticData);
         }
     }
 }
 

出来结果:
