自定义类：无法在数组中比较两个元素

Question

我有抽象类元素的列表，当我试图解决它，我得到与“无法比较数组中的两个元素”

消息异常抽象类：

​​

派生类：

public class Interrior : Node 
{ 
    public Interrior(byte age, Node left, Node right) 
    { 
     Age = age; 
     Left = left; 
     Right = right; 
     Weight = Left.Weight + Right.Weight; 
    } 
    public byte Age { get; } 
    public Node Left { get; } 
    public Node Right { get; } 
    public override int CompareTo(Interrior node) 
    { 
     var result = CompareWeights(node); 
     if (result == 0) result = this.Age < node.Age ? -1 : 1; 
     return result; 
    } 
    public override int CompareTo(Leaf node) 
    { 
     var result = CompareWeights(node); 
     if (result == 0) result = 1; 
     return result; 
    } 
} 
public class Leaf : Node 
{ 
    public Leaf(byte symbol) 
    { 
     Symbol = symbol; 
     Weight = 1; 
    } 
    public byte Symbol { get; } 
    public override int CompareTo(Interrior node) 
    { 
     var result = CompareWeights(node); 
     if (result == 0) result = -1; 
     return result; 
    } 

    public override int CompareTo(Leaf node) 
    { 
     var result = CompareWeights(node); 
     if (result == 0) result = this.Symbol < node.Symbol ? -1 : 1; 
     return result; 
    } 
} 

有人能告诉我什么，我做错了什么？我想创建节点列表并调用一个排序方法，谢谢。

您没有可用的余额<Node>。实现它，并将它委托给您为Interior和Leaf实施的那些。
