C# 构造函数缺陷

Question

这是我的部分代码：

class Tiger: Animal,IPredator
{
private double weight;
public static double AvgWeight;
public static int Population;
public static double TotalWeight;
public Tiger(double aWeight):this(aWeight,"Savannah"){}
public Tiger(double aWeight, params string[] aHabitat) : base(aWeight,"Panthera Tigris", "Mammalia", aHabitat)
{
    Population++;
    TotalWeight += Weight;
    AvgWeight = TotalWeight / Population;
    Console.WriteLine($"Let's all welcome our new Tiger: {Weight} kilos. Average pride weight: {AvgWeight}");
}
public  override double Weight
{
    get
    {
        return weight;
    }

    set
    {
        TotalWeight -= weight;
        weight = value;
        TotalWeight += weight;
        AvgWeight = TotalWeight / Population;
    }
}

看起来不错，但是当我创建一个实例并检查构造函数时，它显示新猫体重值的两倍。

Animal部分代码：

 abstract class Animal
     {
    private string kind;
    private string @class;
    public List<string> Habitat = new List<string>();
    public virtual double Weight { get; set; }
    public string Kind { get { return kind; } set { } }
    public string @Class { get { return kind; } set { Console.WriteLine("Class cannot be changed"); } }

    public Animal(double aWeight,string aKind, string aClass,params string[] aHabitat)
    {
        kind = aKind;
        @class = aClass;
        Habitat.AddRange(aHabitat);
        Weight = aWeight;
    }

我试图避免这些问题，这就是为什么我在 Tiger 中添加了一个额外的双字段。但我需要 Tiger's 像这样工作，而 Animals 绝对应该有重量属性。

好的，问题不在于继承或静态方法。它与 setter 和构造函数中的字符串相同：TotalWeight += value;
