C#中的多线程使用 -- Thread 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();
