C#抽象方法和公共(public)代码

Question

我想用抽象方法声明一些继承抽象类的类。 我还希望子类中的某些方法自动调用公共(public)代码(即日志代码)

public abstract class AbstractClass
{
    public abstract void AbstractMethod();
    public void CommonCode()
    {
        //do something
    }
}

public class ChildClass : AbstractClass
{
    public void AbstractMethod()
    {
        //automatically call CommonCode in base class
        //do something
    }
}

事件可以帮助我吗？

不必太花哨，您可以使抽象方法成为您希望继承者执行的操作的“核心”，并从基类的包装器方法中调用它。例如:

public abstract class AbstractClass
{
    // Note that this protected since consumers won't call it directly
    protected abstract void AbstractMethod();

    // Instead, consumers will use this method which calls CommonCode
    // before the abstract method.
    public void AbstractMethodWrapper()
    {
        CommonCode();
        AbstractMethod();
    }

    public void CommonCode()
    {
        //do something
    }
}

public class ChildClass : AbstractClass
{
    protected override void AbstractMethod()
    {
        // The wrapper method in the base handles calling common code
        //do something
    }
}
