线程使用方法 带参 不带参 线程类

现在C#已经建议摈弃使用 Suspend, Resume 暂停/恢复线程, 也尽量少用 Abort方法中断一个线程.

建议使用线程的同步手段有: Mutex、ManualResetEvent、AutoResetEvent, Monitor.

下面再对此进行详细描述.

Thread类的构造函数有2类:

一种是不带参数(ThreadStart 委托) --

public Thread(ThreadStart start);

另一种是带参数(ParameterizedThreadStart 委托) --

public Thread(ParameterizedThreadStart start);

ParameterizedThreadStart 委托签名:

public delegate void ParameterizedThreadStart(Object obj);

示例:

1. 不带参数:

// 定义线程方法:

private static void ThreadMain()
{
Console.WriteLine("This is other thread main method.");
}

　　　　// 调用:

Thread mythread = new Thread(ThreadMain);
mythread.Start();

2. 带参数:

// 定义线程方法:

private static void MainThreadWithParameters(object o)
{
Data d = (Data)o; //类型转换
Console.WriteLine("Running in a thread, received {0}", d.Message);
}

public struct Data
{
public string Message;
}

// 调用:

var data = new Data { Message = "Info" };
Thread t2 = new Thread(MainThreadWithParameters);
t2.Start(data); // 传入参数

3. 通过定义类传递参数:

// 定义存放数据和线程方法的类:

public class MyThread
{
private string message;
public MyThread(string data)
{
this.message = data;
}
public void ThreadMethod()
{
Console.WriteLine("Running in a thread, data: {0}", this.message); 
}
}

// 调用

var obj = new MyThread("info");
Thread myThread = new Thread(obj.ThreadMethod); //ThreadStart 委托
mythread.Start();
