这篇文章主要介绍mongodb如何使用c#驱动数据插入demo,文中介绍的非常详细,具有一定的参考价值,感兴趣的小伙伴们一定要看完!
Mongodb提供了多种开发语言的驱动,java,python,c++,c# 等,这里选用c#驱动作为测试;
首先上mongo官网下载驱动。Ps:官方网站经常连接不顺利。
还不如直接在vs的nuget管理包中搜索mongoDB.driver.
需要引入的命名空间:
using MongoDB.Bson;using MongoDB.Driver;
Driver是驱动核心,Bson是和数据格式相关的;
定义一个mongo客户端,一个mongodb,一个数据集合;
protected staticIMongoClient client;protected staticIMongoDatabase database;protected staticIMongoCollection collection;
连接上MongoDB
//定义连接client = new MongoClient("mongodb://127.0.0.1:27017");//获取test数据库database = client.GetDatabase("test"); //获取test数据库中的集合bioscollection = database.GetCollection("bios");
这里解释说明下:首先你得让mongod(mongo的服务端)运行起来,不然服务端都没开,怎么连接呢;目前测试还没有涉及到安全以及用户权限数据库管理这块,所以这里的连接都是使用的默认不带用户登录验证;
需求注意的是,如果我们建立的是控制台程序,那么这个连接必须写地址必须带端口,就像上面所写;
如果是建立的一个MVC web,你仅仅是测试数据插入,在这种无安全验证的方式下,你可以省去连接字符串。
如下图;
接下来就是定义一个测试数据:
var document =new BsonDocument { { "address" , newBsonDocument { { "street","2 Avenue" }, { "zipcode","10075" }, { "building","1480" }, { "coord",new BsonArray { 73.9557413, 40.7720266 } } } }, { "borough", "Manhattan"}, { "cuisine", "Italian"}, { "grades", new BsonArray { new BsonDocument { { "date",new DateTime(2014, 10, 1, 0, 0, 0, DateTimeKind.Utc) }, { "grade","A" }, { "score",11 } }, new BsonDocument { { "date",new DateTime(2014, 1, 6, 0, 0, 0, DateTimeKind.Utc) }, { "grade","B" }, { "score",17 } } } }, { "name", "Vella"}, { "restaurant_id","41704620" } };
最后调用InsertOneAsync()方法;
collection.InsertOneAsync(document);
最终插入结果:
这里使用shell来看数据的话就太不直观了,这里使用的是比较常用的一个mongodb可视化管理工具Robomongo
附上代码:
using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;using MongoDB.Bson;using MongoDB.Driver;namespace mongodbInsert{ class Program { protected static IMongoClient client; protected static IMongoDatabase database; protected static IMongoCollection collection; static void Main(string[] args) { client = new MongoClient("mongodb://127.0.0.1:27017"); database = client.GetDatabase("test"); collection = database.GetCollection("bios"); for (int i = 0; i < 14; i++) { var document = new BsonDocument { { "address" , new BsonDocument { { "street", "2 Avenue" }, { "zipcode", "10075" }, { "building", "1480" }, { "coord", new BsonArray { 73.9557413, 40.7720266 } } } }, { "borough", "Manhattan" }, { "cuisine", "Italian" }, { "grades", new BsonArray { new BsonDocument { { "date", new DateTime(2014, 10, 1, 0, 0, 0, DateTimeKind.Utc) }, { "grade", "A" }, { "score", 11 } }, new BsonDocument { { "date", new DateTime(2014, 1, 6, 0, 0, 0, DateTimeKind.Utc) }, { "grade", "B" }, { "score", 17 } } } }, { "name", "Vella" }, { "restaurant_id", "41704620" } }; collection.InsertOneAsync(document); } Console.WriteLine(); Console.ReadLine(); } }}以上是"mongodb如何使用c#驱动数据插入demo"这篇文章的所有内容,感谢各位的阅读!希望分享的内容对大家有帮助,更多相关知识,欢迎关注行业资讯频道!
