c# - C#运行时错误声明主体，因为它没有被标记为抽象，外部或局部

Question

嗨，我在运行这段代码时遇到了一些麻烦，因为我收到Kennel.Kennel()的运行时错误，必须声明一个主体，因为它没有被标记为抽象，外部或部分。请提供建议和帮助。非常感激。

using System;
using System.Collections.Generic;
using System.Text;

public class Kennel : IComparable<Kennel>
{
    private string _name;
    private string _breed;

    public string Name
    {

        get { return _name; }
        set { _name = value; }
    }

    public string Breed
    {
        get { return _breed; }
        set { _breed = value; }
    }

    public override string ToString()
    {
        return String.Format("Name: {0}, Breed: {1}", Name, Breed);
    }

    public Kennel();

    public Kennel(string name, string breed)
    {
        this._name = name;
        this._breed = breed;
    }

    #region #IComparable<Kennel> Members

    public int CompareTo(Kennel other)
    {
        return other.Name.CompareTo(this.Name);
    }

    #endregion

}


class Run
{
public static void Main()
        {
            List<Kennel> kennels = new List<Kennel>();
            kennels.Add(new Kennel("Alan", "French Bulldog"));
            kennels.Add(new Kennel("Larry", "English Terrier"));
            kennels.Add(new Kennel("Moe", "Gold Retriever"));
            kennels.Add(new Kennel("Curly", "Chihuahua"));

            foreach (Kennel k in kennels)
            {
                Console.WriteLine("Name: {0}, Breed: {1}", k.Name, k.Breed);
            }


            kennels.Sort();
            foreach (Kennel k in kennels)
            {
                Console.WriteLine("Name: {0}, Breed: {1}", k.Name, k.Breed);
            }


        }
}

public Kennel();

这没有道理。

对于空的无参数构造函数，您仍然需要一个主体:

public Kennel()
{}
