一段代码如下：
public class ClassA {
  public ClassA() { }
 
  public virtual void FunA() {}
  public virtual void FunB() {}
}

public class ClassB {
  public ClassB() { }
 
  public override void FunA() {}
  public override void FunB() {}
}

public class ClassC {
  public ClassC() { }
 
  public override void FunA() {}
  public override void FunB() {}
}

public class ClassD {
  public ClassD() { }
 
  public override void FunA() {}
  public override void FunB() {}
}

ClassD instance = new ClassD();
怎么写可以在new ClassD时，按照
ClassA.FunA
ClassB.FunA
ClassC.FunA
ClassD.FunA
ClassA.FunB
ClassB.FunB
ClassC.FunB
ClassD.FunB
的次序执行，在new ClassC时，按照
ClassA.FunA
ClassB.FunA
ClassC.FunA
ClassA.FunB
ClassB.FunB
ClassC.FunB
的次序执行，在new ClassB时，按照
ClassA.FunA
ClassB.FunA
ClassA.FunB
ClassB.FunB
的次序执行？
