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();
