多线程的顺序执行
有4个类，分别开一个线程，怎样才能按照a-b-c-d的顺序执行呢？ 最好能贴出代码窗体代码：
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
A a = new A();
B b = new B();
C c = new C();
D d = new D();
Thread t1=new Thread (new ThreadStart (a.a));
Thread t2 = new Thread(new ThreadStart(b.b));
Thread t3 = new Thread(new ThreadStart(c.c));
Thread t4 = new Thread(new ThreadStart(d.d));
t1.Start();
t2.Start();
t3.Start();
t4.Start();
}
类代码：
class A
{
public void a()
{
//方法
}
}
class B
{
public void b()
{
//方法
}
}
class C
{
public void c()
{
//方法
}
}
class D
{
public void d()
{
//方法
}
}
怎样才能按照a-b-c-d的顺序执行,最好能贴出代码 --------------------编程问答-------------------- 咋没人回复呢？ --------------------编程问答-------------------- Join --------------------编程问答-------------------- 如果你是说执行完A以后，在执行B可以yon下面的方法
--------------------编程问答-------------------- 如果说是A开始以后接着执行B，则这样：
using System;
using System.Collections.Generic;
using System.Text;
using System.Text.RegularExpressions;
using System.Threading;
namespace test
{
class Program
{
static void Main(string[] args)
{
A a = new A();
B b = new B();
C c = new C();
D d = new D();
Thread t1 = new Thread(new ThreadStart(a.a));
Thread t2 = new Thread(new ThreadStart(b.b));
Thread t3 = new Thread(new ThreadStart(c.c));
Thread t4 = new Thread(new ThreadStart(d.d));
t1.Start();
t1.Join();
t2.Start();
t2.Join();
t3.Start();
t3.Join();
t4.Start();
t4.Join();
Console.Read();
}
}
class A
{
public void a()
{
//方法
Console.WriteLine("Execute a().\n");
}
}
class B
{
public void b()
{
//方法
Console.WriteLine("Execute b().\n");
}
}
class C
{
public void c()
{
//方法
Console.WriteLine("Execute c().\n");
}
}
class D
{
public void d()
{
//方法
Console.WriteLine("Execute d().\n");
}
}
}

楼上都说了 --------------------编程问答-------------------- 晕 提交慢了... --------------------编程问答-------------------- 设置一个全局变量 --------------------编程问答-------------------- 你可以考虑把他们设置为不同的优先级别 --------------------编程问答-------------------- 是执行完A后执行B，执行完B后执行C，执行完C后执行D
用join（）方法，主线程也堵塞了，和不用线程有什么区别？ --------------------编程问答-------------------- 我有个笨办法，在A方法里结束的地方执t2.start()
在B的结束处执行t3.start()
类推～～ --------------------编程问答-------------------- 我的第二种方法可以阿，只要A开始执行了，就可以执行B了.. --------------------编程问答-------------------- 如果前一个线程因为某种原因挂起或阻塞怎么办??我认为这里的方法除了我的以外其他的都行不通 --------------------编程问答-------------------- 奇怪
为什么不用一个方法呢？？
public void E
{
a();
b();
c();
d();
}
用一个线程就可以了啊。。。 --------------------编程问答-------------------- 可能他的几个方法是有可能无法执行完的吧.... --------------------编程问答-------------------- to:newnazi
线程一开始运行怎么会挂起？优先级别高的就一定会先执行吗？
楼主的意思只是按顺序执行，不过到底是怎么按顺序执行没有说清楚。 --------------------编程问答-------------------- LS:
t1.Start 是什么意思? 你能理解吗?
如果这个线程无法得到时间片当然会被挂起 既是Start方法你确定证哪个线程先被执行吗?
如果用一个线程到可以保证前面的代码先被执行. --------------------编程问答-------------------- 我觉得这个问题本身就很有问题.
既然不需要异步,又要顺序,何需要多线程??
a();
b();
c();
d();
不是最简单最好么? --------------------编程问答-------------------- 自用C#以来，很少用到涉及多线程的东西，最多的是System.Threading.Thread.Sleep(int x); --------------------编程问答-------------------- 路过.................. --------------------编程问答--------------------
