Question

C# 下面这些代码 出现错误Customerlnfo不实现接口，怎么回事？如果有时间，请讲解一下泛型的意思，谢谢

class Customerlnfo:IComparable<Customerlnfo>
{
public string id{get;set;}
public string name{get;set;}
public string address{get;set;}
public Customerlnfo(string myid,string myname,string myaddress)
{
this.id=myid;
this.name=myname;
this.address=myname;

}
public int ASV(Customerlnfo ASD)
{
return(this.name.CompareTo(ASD.name));//返回按照姓名比较的结果
}

这个错误和泛型没有什么关系。错误出在：你的CustomInfo类继承了IComparable<T>接口，那你在类中就必须实现这个接口！

   class Customerlnfo : IComparable<Customerlnfo>
    {
        public string id { get; set; }
        public string name { get; set; }
        public string address { get; set; }
        public Customerlnfo(string myid, string myname, string myaddress)
        {
            this.id = myid;
            this.name = myname;
            this.address = myname;

        }
        public int ASV(Customerlnfo ASD)
        {
            return (this.name.CompareTo(ASD.name));//返回按照姓名比较的结果
        }
         
        // 必须实现 IComparable<Customerlnfo>接口  
        public int CompareTo(Customerlnfo other)
        {
           ……
        }
    }
