Question

不确定我做错了什么，但不是直接从基类继承的属性。如果有：

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

   public Fruit()
   {
   }
}

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

   public Citrus()
   {
   }
}

我似乎无法在Citrus课程中设置GroupFruit。谢谢。

您需要在子类的构造函数中初始化它，并且它必须至少为protected：

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

    public Fruit()
    {
    }
}

public class Citrus : Fruit
{

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

继承自基类C＃
