蒙戈德布公约包

如何在C#中使用MongoDB ConventionPack 我有以下代码:

MongoDatabase Repository = Server.GetDatabase(RepoName);
this.Collection = Repository.GetCollection<T>(CollectionName);
var myConventions = new ConventionPack();
myConventions.Add(new CamelCaseElementNameConvention());

约定包是否自动附加到此包。收集?
当我加载一个新对象时,它会自动像这种情况一样保留它吗?
我是否必须在类声明中添加标记(如数据协定)?

您需要

ConventionRegistry中注册包:

var pack = new ConventionPack();
pack.Add(new CamelCaseElementNameConvention());
ConventionRegistry.Register("camel case",
                            pack,
                            t => t.FullName.StartsWith("Your.Name.Space."));

如果要全局应用此功能,可以将最后一个参数替换为更简单的参数,例如 t => true

序列化

和反序列化的工作示例代码(驱动程序 1.8.20、mongodb 2.5.0):

using System;
using System.Linq;
using MongoDB.Bson;
using MongoDB.Bson.Serialization.Conventions;
using MongoDB.Driver;
namespace playground
{
    class Simple
    {
        public ObjectId Id { get; set; }
        public String Name { get; set; }
        public int Counter { get; set; }
    }
    class Program
    {
        static void Main(string[] args)
        {
            MongoClient client = new MongoClient("mongodb://localhost/test");
            var db = client.GetServer().GetDatabase("test");
            var collection = db.GetCollection<Simple>("Simple");
            var pack = new ConventionPack();
            pack.Add(new CamelCaseElementNameConvention());
            ConventionRegistry.Register("camel case", pack, t => true);
            collection.Insert(new Simple { Counter = 1234, Name = "John" });
            var all = collection.FindAll().ToList();
            Console.WriteLine("Name: " + all[0].Name);
        }
    }
}
