我不得不说,mongodb官方驱动在与.net结合上做的不是很好,不是很理想,所以,我决定对它进行了二次封装,这是显得很必然了,每个人都希望使用简单的对象,而对使用复杂,麻烦,容易出错的对象尽而远之,这是正常的,人都是喜欢懒惰的,就像程序员,也是一样,喜欢偷懒,可能说,偷懒是程序员进步的一个标志,呵呵.

下面我是总结的几种标准的操作,主要是针对我封装的官方驱动而方的(MongoOfficialRepository<TEntity>)

1  插入对象和子对象

/// 
        /// 添加对象        /// 
        static public void Insert()        {            List
     
       list = new List
      
       ();            for (int i = 0; i < 10; i++)            {                //添加新对象                list.Add(new Person                {                    Address = new Address                    {                        City = "北京",                        District = "鸾翔凤集",                        Province = "luanxian",                    },                    AddList = new List
       
                {                 new Address                 {                    Seconds=1,                    City = "湖北",                    District = "鸾翔凤集",                    Province = "luanxian",                 },                  new Address                 {                    Seconds=1,                    City = "湖南",                    District = "小区",                    Province = "luanxian",                 }                },                    Age = 35,                    Birthday = DateTime.Now,                    LastContact = DateTime.Now,                    Name = "wangwu"                });            }            repository1.Insert(list);        }
      
     

2 更新对象和子对象集合元素,这是非常不错的功能,对于没有必要更新的记录,可以不去为它赋值

/// 
        /// 集合查询        /// 
        static public void Update()        {            repository1.Update
     
      (i => new Person              {                  Id = "556bfd1b2683c82060c2edd0",                  AddList = new List
      
                  {                    new Address                    {                      Id = "556bfd1b2683c82060c2edd3",                      City = "占占大师123",                      District = "鸾翔凤集",                      Seconds=2                    }                 }              });        }
     

3 分页,多字段查询和排序,这是项目开发中用的最多的东西了,写了个标准的给大家参考

/// 
        /// 分页，排序，查询        /// 
        static public void Select()        {            //排序和检索            var m1 = repository1.GetModel(new            {                Address = new                {                    City = "北京"                },                AddList = new                {                    Seconds = 1                }            }, new { Name = OrderType.Desc }, 1, 20);

4 分组,对于需要按着按些字段进行聚合(统计,求和,总数,最大值,最小值等),及多条件查询,这里有不错的实例

/// 
        /// 分组        /// 
        static public PagedList
     
       Group(string keyword, int? age, int page)        {            Specification
      
        spec = new TrueSpecification
       
        ();            //过滤            if (!string.IsNullOrWhiteSpace(keyword))            {                spec &= new DirectSpecification
        
         (i => i.Name == keyword);            }            if (age.HasValue)            {                spec &= new DirectSpecification
         
          (i => i.Age == age);            }            //分组            var linq = from data1 in repository1.GetModel().Where(spec.SatisfiedBy())                       group data1 by new                       {                           data1.Id,                           data1.Name                       } into g                       select new Person                       {                           Id = g.Key.Id,                           Name = g.Key.Name,                           Total = new Total                           {                               Count = g.Count(),                               Max = g.Max(i => i.Age),                           }                       };            return new PagedList
          
           (linq, page, 10); }
          
         
        
       
      
     

OK,以上是针对我的MongoDB仓储进行的一些二次说明,感觉还是比较有必要的,呵呵.
