这是我的代码。我无法弄清楚为什么这段代码给出“由于StackOverFlowException而终止了进程”。

namespace SadiSDAL4
{
    class Program
    {
        static void Main(string[] args)
        {
            PrivateVehical privateV = new PrivateVehical("001");
            PrivateVehical pVehical = (PrivateVehical)privateV.Clone();
            Console.WriteLine("Cloned : {0}", privateV.name);
            Console.WriteLine("Cloned : {0}", pVehical.name);
            privateV.name = "Sadia's Car";
            Console.WriteLine("Cloned : {0}", privateV.name);
            Console.WriteLine("Cloned : {0}", pVehical.name);
            pVehical.name = "Waheed's Car";
            Console.WriteLine("Cloned : {0}", privateV.name);
            Console.WriteLine("Cloned : {0}", pVehical.name);
            Console.WriteLine(privateV.GetHashCode().ToString());
            Console.WriteLine(pVehical.GetHashCode().ToString());
            PublicVehical publicV = new PublicVehical("002");
            Console.WriteLine(publicV.id);
            PublicVehical pubVehi = (PublicVehical)publicV.Clone();
            Console.WriteLine("Cloned : {0}", pubVehi.id);
        }
    }
    abstract class Vehical
    {
        private string vehicalId = "01";
        public string name = "Car_1";
        public Vehical(string id)
        {
            this.vehicalId = id;
        }
        public string id
        {
            get { return id; }
            set { this.vehicalId = id; }
        }
        public abstract Vehical Clone();
    }
    class PrivateVehical : Vehical
    {
        public PrivateVehical(string id)
            : base(id)
        {

        }
        public override Vehical Clone()
        {
            return (Vehical)this.MemberwiseClone();
        }
    }
    class PublicVehical : Vehical
    {
        public PublicVehical(string id)
            : base(id)
        {

        }
        public override Vehical Clone()
        {
            return (Vehical)this.MemberwiseClone();
        }
    }
}

这是输出。

有人可以解释原因吗?为什么它在第一部分起作用而不在另一部分起作用?

最佳答案

看一下这段代码:

    public string id
    {
        get { return id; }
        set { this.vehicalId = id; }
    }

具体来说get { return id; }。您正在将属性返回给自身,从而导致SO错误。

这是您想要的吗?
    public string id
    {
        get { return this.vehicalId; }
        set { this.vehicalId = value; }
    }
