消息队列学习

学习了beniao的消息队列，自己也敲打了些代码写出了自己设计的简单消息队列

1 简单的消息队列的Demo

 

//附带的实体类
    public class people
    {
        private string _name;
        private int? _age;
        private DateTime _birthday;
        private bool _IsMale;

        public string Name
        {
            get { return _name; }
            set { _name = value; }
        }
        public int? Age
        {
            get { return _age; }
            set { _age = value; }
        }
        public DateTime Birthday
        {
            get { return _birthday; }
            set { _birthday = value; }
        }
