class GrandParent
{
public virtual void Foo() { ... }
}
class Parent : GrandParent
{
public override void Foo()
{
base.Foo();
//Do additional work
}
}
class Child : Parent
{
public override void Foo()
{
//How to skip Parent.Foo and just get to the GrandParent.Foo base?
//Do additional work
}
}
如上面的代码所示,我如何使Child.Foo()调用到GrandParent.Foo()而不是进入Parent.Foo()？ base.Foo()首先将我带到Parent类.
解决方法
你的设计是错误的,如果你需要这个.
相反,将每类逻辑放在DoFoo中,不需要调用base.DoFoo.
相反,将每类逻辑放在DoFoo中,不需要调用base.DoFoo.
class GrandParent
{
public void Foo()
{
// base logic that should always run here:
// ...
this.DoFoo(); // call derived logic
}
protected virtual void DoFoo() { }
}
class Parent : GrandParent
{
protected override void DoFoo()
{
// Do additional work (no need to call base.DoFoo)
}
}
class Child : Parent
{
protected override void DoFoo()
{
// Do additional work (no need to call base.DoFoo)
}
}
