一、设置配置信息

  //连接信息        static string conn = "mongodb://localhost";        static string database = "test";        static string collection = "person";        static MongoServer mongodb = MongoServer.Create(conn);//连接数据库        static MongoDatabase db = mongodb.GetDatabase(database);//选择数据库名        static MongoCollection mc = db.GetCollection(collection);//选择集合，相当于表

二、插入数据库

public static void Insert(Person p){　　mc.Insert(p);}public static void Insert(BsonDocument b)  {　　mc.Insert(b);}

三、更新数据库

   　　public static void Update(Person p)        {            BsonDocument bd = BsonExtensionMethods.ToBsonDocument(p);            IMongoQuery query = Query.EQ("_id", p._id);            mc.Update(query, new UpdateDocument(bd));        }        public static void Update(QueryDocument q,UpdateDocument u)        {            mc.Update(q, u);        }

四、删除某条记录

 public static void Delete(int id) {     mc.Remove(Query.EQ("_id", id)); }

五、查询数据库

        public static Person Find(int id)        {            return mc.FindOneAs<Person>(Query.EQ("_id", id));        }        public static MongoCursor<Person> FindAll()        {            return mc.FindAllAs<Person>();        }        public static MongoCursor<Person> Select(QueryDocument q)        {            return mc.FindAs<Person>(q);        }

六、统计数据个数

 public static long Count(QueryDocument q)  {       return mc.Count(q); }

七、排序和分页

   public static MongoCursor<Person> SkipAndLimit(int a, int b)        {            return mc.FindAllAs<Person>().SetSkip(a).SetLimit(b);        }

八、应用与示例

   static void Main(string[] args)        {            mongodb.Connect();            //var person = Find(124);            //Console.WriteLine(person.Name);            //person.Name = "guizhu";            //Update(person);            //Console.WriteLine(person.Name);            var query = new QueryDocument { { "_id",13} };            var update = new UpdateDocument { { "$set", new QueryDocument { { "PassWord", "aaaaa" } } } };            Update(query,update);            //对象插入            //Person p = new Person { _id = 12, Name = "hello", PassWord = "4444" };            //Insert(p);            //BsonDocument 插入            //BsonDocument b = new BsonDocument();            //b.Add("_id", 13);            //b.Add("Name", "world");            //b.Add("PassWord", "6666");            //Insert(b);            //var p= FindAll();            //foreach (var person in p)            //{            //    Console.WriteLine(person.Name);            //}            //QueryDocument query = new QueryDocument();            //BsonDocument b = new BsonDocument();            //b.Add("$gte", 123);            //b.Add("$lt", 125);            //query.Add("_id", b);            //var p=Select(query);            //foreach (var person in p)            //{            //    Console.WriteLine(person.Name);            //}            //Console.WriteLine(Count(query));            //FieldsDocument f = new FieldsDocument();            //f.Add("Name", 1);            //MongoCursor<Person> m = mc.FindAs<Person>(query).SetFields(f);            //foreach (var person in p)            //{            //    Console.WriteLine(person.Name);            //}            //SortByDocument s = new SortByDocument();            //s.Add("_id", 1);//-1=DESC            //var p = Sort(s);            //foreach (var person in p)            //{            //    Console.WriteLine(person.Name);            //}            //var p = SkipAndLimit(1, 3);            //foreach (var person in p)            //{            //    Console.WriteLine(person.Name);            //}                        //Delete(12);            Console.WriteLine("完成");            Console.ReadLine();        }

  class Person    {        public int _id;        public string Name;        public string PassWord;    }
