从基类 C# 继承

Question

Not sure what i'm doing wrong but are Properties not directly inherited from a base class. If there is:

public class Fruit{
   string[] GroupFruit{get;set;}

   public Fruit()
   {
   }
}

public class Citrus : Fruit{
    GroupFruit = new string[]{"lemon", "lime", "orange"}

   public Citrus()
   {
   }
}

I don't seem to be able to set GroupFruit in the Citrus class. Thanks.

You need to initialize it in the constructor of the child class and it must be at least protected :

public class Fruit
{
    protected string[] GroupFruit { get; set; }

    public Fruit()
    {
    }
}

public class Citrus : Fruit
{

    public Citrus()
    {
        base.GroupFruit = new string[] {"lemon", "lime", "orange"};
    }
}
