C#don'；t重写重写方法

是否有

属性

或

模式

告诉编译器不允许重写可重写方法

例如：

车辆

public class Vehicle
{
    public virtual void Start() { }
}

public class Car : Vehicle
{
    // ################
    [DontAllowOverrideAgain] //I need something like this attribute
    // ################
    public override void Start()
    {
        // Todo => codes that every car must invoke before start ...
        CarStart();
        // Todo => codes that every car must invoke after start ...
    }

    public virtual void CarStart() { }
}

public class CoupeCar : Car
{
    // throw and error or show a message to developer
    public override void Start() { }

    public override void CarStart() { }
}

汽车

public class Vehicle
{
    public virtual void Start() { }
}

public class Car : Vehicle
{
    // ################
    [DontAllowOverrideAgain] //I need something like this attribute
    // ################
    public override void Start()
    {
        // Todo => codes that every car must invoke before start ...
        CarStart();
        // Todo => codes that every car must invoke after start ...
    }

    public virtual void CarStart() { }
}

public class CoupeCar : Car
{
    // throw and error or show a message to developer
    public override void Start() { }

    public override void CarStart() { }
}

CoupeCar

public class Vehicle
{
    public virtual void Start() { }
}

public class Car : Vehicle
{
    // ################
    [DontAllowOverrideAgain] //I need something like this attribute
    // ################
    public override void Start()
    {
        // Todo => codes that every car must invoke before start ...
        CarStart();
        // Todo => codes that every car must invoke after start ...
    }

    public virtual void CarStart() { }
}

public class CoupeCar : Car
{
    // throw and error or show a message to developer
    public override void Start() { }

    public override void CarStart() { }
}

当然，只需将第一个覆盖创建为

sealed

，这将导致开发人员可以看到的编译时失败

public class Car : Vehicle
{
    public sealed override void Start()
    {
        // Todo => codes that every car must invoke before start ...
        CarStart();
        // Todo => codes that every car must invoke after start ...
    }

    public virtual void CarStart() { }
}

给你，用密封的

非常感谢，我也不知道如何使用方法。
