asp.net（C#） 中 怎么使用 MongoDb

1. 先引用以下Dll（如果找不到 到gethub上下载源代码自己编译 特别是MongoDB.Driver.Legacy.dll 我自己找了半天没找到）：

MongoDB.Bson.dll

MongoDB.Driver.Core.dll

MongoDB.Driver.dll

MongoDB.Driver.Legacy.dll

 

2. 以下是测试代码：

using System;

using MongoDB.Bson;

using MongoDB.Driver;

using MongoDB.Driver.Linq;

using MongoDB.Driver.Builders;



namespace MongoDbDemo

{

    public class MongoDbHelper

    {

        public static void TestMongoDb()

        {

            var connectionString = "mongodb://192.168.201.140:27017";

            var client = new MongoClient(connectionString);

            var server = client.GetServer();

            var database = server.GetDatabase("test");

            var collection = database.GetCollection<Entity>("entities");



            var entity = new Entity { Name = "Tom" };

            collection.Insert(entity);

            var id = entity.Id;



            var query = Query<Entity>.EQ(e => e.Id, id);

            entity = collection.FindOne(query);



            entity.Name = "Dick";

            collection.Save(entity);



            var update = Update<Entity>.Set(e => e.Name, "Harry");

            collection.Update(query, update);



            collection.Remove(query);

        }

    }



    public class Entity

    {

        public ObjectId Id { get; set; }



        public string Name { get; set; }

    }

}
