无法从C#中的线程类继承? [英] Unable to inherit from a Thread Class in C# ?

问题描述

类 Thread 是一个密封的类，意味着它不能继承，我需要一个可重用的 Thread 实例，该实例应从 Thread 继承类.有谁知道我可以重新使用胎面吗?

The class Thread is a sealed class meaning it cannot be inherited from and I need an instance of a reusable Thread that should inherit from the Thread class. Does anyone have an idea how i can reuse tread ?

推荐答案

正如您自己指出的， Thread 是一个密封的类.显然，这意味着您不能从中继承.但是，您可以创建自己的 BaseThread 类，使用

As you yourself noted, Thread is a sealed class. Obviously this means you cannot inherit from it. However, you can create your own BaseThread class that you can inherit and override to provide custom functionality using Composition.

abstract class BaseThread
{
    private Thread _thread;

    protected BaseThread()
    {
        _thread = new Thread(new ThreadStart(this.RunThread));
    }

    // Thread methods / properties
    public void Start() => _thread.Start();
    public void Join() => _thread.Join();
    public bool IsAlive => _thread.IsAlive;

    // Override in base class
    public abstract void RunThread();
}

public MyThread : BaseThread
{
    public MyThread()
        : base()
    {
    }

    public override void RunThread()
    {
        // Do some stuff
    }
}

您明白了.
