指在一線程里面調用另一線程join方法時，表示將本線程阻塞直至另一線程終止時再執行???
? 比如??

?1using?System;
?2
?3namespace?TestThreadJoin
?4{
?5????class?Program
?6????{
?7????????static?void?Main()
?8????????{
?9????????????System.Threading.Thread?x?=?new?System.Threading.Thread(new?System.Threading.ThreadStart(f1));
10????????????x.Start();
11????????????Console.WriteLine("This?is?Main.{0}",?1);
12????????????x.Join();
13????????????Console.WriteLine("This?is?Main.{0}",?2);
14????????????Console.ReadLine();
15????????}
16????????static?void?f1()
17????????{
18????????????System.Threading.Thread?y?=?new?System.Threading.Thread(new?System.Threading.ThreadStart(f2));
19????????????y.Start();
20????????????y.Join();
21????????????Console.WriteLine("This?is?F1.{0}",1);
22????????}
23
24????????static?void?f2()
25????????{
26????????????Console.WriteLine("This?is?F2.{0}",?1);
27????????}
28????}
29}
這兒有三個線程在處理(包括主線程),大家可看看執行結果.
結果:
This is Main.1
This is F2.1
This is F1.1
This is Main.2

如果: 注釋//? x.Join();
結果:
This is Main.1
This is Main.2
This is F2.1
This is F1.1
