c#重载等号和不等号

public abstract class IdenticalObject
{
    public IdenticalObject(string id)
    {
        this.ID = id;
    }

    public string ID { get; private set; }

    public static bool operator ==(IdenticalObject obj1, IdenticalObject obj2)
    {
        return obj1.ID == obj2.ID;
    }

    public static bool operator !=(IdenticalObject obj1, IdenticalObject obj2)
    {
        return obj1.ID != obj2.ID;
    }

    public override bool Equals(object obj)
    {
        return this.Equals(obj);
    }

    public override int GetHashCode()
    {
        return base.GetHashCode();
    }
}

继承此类，就可以实现了
