Question

我有一个看起来像这样的课程：

   public class SyncData<T>
   {
        [BsonId]
        [BsonIgnoreIfDefault]
        public ObjectId MongoId { get; set; }

        [BsonIgnore]
        public string Id => MongoId.ToString();

        public T Data { get; set; }

        //etc.

   }

有时，Data对象有一个Id字段，C＃在将其保存到Mongo时会自动序列化为_id。

如何让它停止将Id序列化为_id而无需访问通用T Data属性中存储的任何类型。

如果您以某种方式预先了解类型：

给定类型

#!/bin/sh
# git-fetch-log: Ultimate git fetch-log
#
# It shows the diferences of `local...remote` if both side exists and there
# are differences. Useful to find out what you have to do: `merge`, `rebase`,
# `push`, etc. The arguments passed to log.
#
# Place it somewhere on Your `$PATH` and execute by the `git fetch-log`
# command.

你会在申请开始时这样做：

public class SomeTypeWithAnIdProperty
{
    public ObjectId Id { get; set; }
}

如果您不了解这些类型，但您对它们有所了解，例如： - 他们都实现了某个界面或 - 他们都坐在某个名称空间或 - 您可以列出所有其他类型的白名单然后你可以做这样的事情（再次，在你的应用程序的开始）：

BsonClassMap.RegisterClassMap<SomeTypeWithAnIdProperty>(cm => cm.UnmapProperty(c => c.Id));

子文档中的Id在Mongo C＃驱动程序中序列化为_id
