C# Thread.Join()用法的理解 轉

指在一線程裏面調用另外一線程join方法時，表示將本線程阻塞直至另外一線程終止時再執行
好比

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),你們可看看執行結果.
結果:
This is Main.1
This is F2.1
This is F1.1
This is Main.2

若是: 註釋// x.Join();
結果:
This is Main.1
This is Main.2
This is F2.1
This is F1.1
