使用NoRM操作MongoDB

NoRM是.NET平台下MongoDB的第三方驱动，可以使用强类型的类操作MongoDB。使用NoRM非常简单，只需要在工程中引用Norm.dll即可。下面来看一个例子。

首先建立一个表示人员信息的模型

class Person
    {
        [MongoIdentifier]
        publicstring ID
        {
            get
            {
                return _id;
            }
        }
        publicstring Name { get; set; }
        publicint Age { get; set; }
        public List<string> Phone { get; set; }

        privatestring _id;

        public Person()
        {
            _id = Guid.NewGuid().ToString();
            Phone =new List<string>();
        }

        publicvoid AddPhone(string phone)
        {
            Phone.Add(phone);
        }
    }

 接下来连接数据库

using (var db =new Mongo("Person", "127.0.0.1", "27017", null))
{
        var personColl = db.Database.GetCollection<Person>("Person");
}

 新增数据并显示

Person person1 =new Person();
person1.Name ="Person1";
person1.Age =1;
person1.AddPhone("13500000001");
person1.AddPhone("13500000002");

Person person2 =new Person();
person2.Name ="Person2";
person2.Age =2;
person2.AddPhone("13500000003");
person2.AddPhone("13500000004");

personColl.Insert(person1);
personColl.Insert(person2);
ShowPersonList(personColl);

显示部分代码如下：

privatestaticvoid ShowPersonList(IMongoCollection<Person> personColl)
        {
            foreach (Person person in personColl.AsQueryable())
            {
                Console.WriteLine("Person Name is {0}, age is {1}", person.Name, person.Age.ToString());
                string phoneInfo ="Phone Numbers:";
                foreach (var phone in person.Phone)
                {
                    phoneInfo += phone +"";
                }
                Console.WriteLine(phoneInfo);
            }
            Console.WriteLine("Person Numbers:{0}", personColl.Count());
        }

修改数据

person2.Phone.RemoveAt(0);
person2.Age =3;
personColl.Save(person2);
ShowPersonList(personColl);

删除数据

personColl.Delete<Person>(person1);
ShowPersonList(personColl);

结果显示如下：
