MongoDB C＃驱动程序使用动态对象进行序列化 [英] MongoDB C# Driver Serialization with dynamic objects

问题描述

我有一个模型，如下所示：

  public class Record 
 {
 public Record（）
 {
 Created = DateTime.Now; 
} 
 
 public string Id {get;组; } 
 
 public string ApplicationId {get;组; } 
 
 public Dictionary< string，dynamic>价值{get;组; } 
 
 public DateTime Created {get;组;使用MongoDB C＃驱动程序存储在MongoDB中的
 
  

当我做这样的事情时，这样做很棒：

  {
 applicationId：52f52db8008a280f583c9ff6，
 values： {
52f9410a324e68055f39f8c0：245234 
52f941096d82a531e700e56b：sdfasdf
52fa4a96e0b2e0d4e61d0a03：52fa4a9b91c477e367ab99e6
} 
} 
  

但是当我尝试添加一个字符串数组，如：

  {
 applicationId：52f52db8008a280f583c9ff6，
 values：{
52f9410a324e68055f39f8c0：245234 
52f941096d82a531e700e56b：sdfasdf
 52fa4a96e0b2e0d4e61d0a03：52fa4a9b91c477e367ab99e6
52fa85ea16f04a6151e4ea51：[52fa85f2d2ffa4cbdcf538e8，52fa85f205505f671f3d0d7b] 
} 
} 
  

当我尝试在文档上执行GET时，会给我以下错误：

  MongoDB.Driver.dll中发生类型为System.IO.FileFormatException的异常，但是n在用户代码中处理
附加信息：反序列化类API.Models.Record.Record的Values属性时出错：无法创建抽象类。 
  

如果我看看它保存的数据库，但它真的很漂亮：

$ b $任何人都有任何关于动态和mongo的经验？

解决方案

更新： 动态现在由v2.0驱动程序支持。

使用动态和 MongoDB 的C＃驱动程序。以下是关于它的 jira ticket 。

从描述中

我们还没有确定在哪个版本中我们可能会添加对C＃动态类型的支持。这张票是您可以评论该功能的可取性和/或投票的地方。

I've got a model that looks like:

public class Record
{
    public Record()
    {
        Created = DateTime.Now;
    }

    public string Id { get; set; }

    public string ApplicationId { get; set; }

    public Dictionary<string, dynamic> Values { get; set; }

    public DateTime Created { get; set; }
}

that's stored in MongoDB using the MongoDB C# Driver. This works GREAT when I do things like:

{
    applicationId: "52f52db8008a280f583c9ff6",
    values: {
     "52f9410a324e68055f39f8c0": 245234
     "52f941096d82a531e700e56b": "sdfasdf"
     "52fa4a96e0b2e0d4e61d0a03": "52fa4a9b91c477e367ab99e6"
    }
}

but when I try to add an array of strings like:

{
    applicationId: "52f52db8008a280f583c9ff6",
    values: {
     "52f9410a324e68055f39f8c0": 245234
     "52f941096d82a531e700e56b": "sdfasdf"
     "52fa4a96e0b2e0d4e61d0a03": "52fa4a9b91c477e367ab99e6"
     "52fa85ea16f04a6151e4ea51": [ "52fa85f2d2ffa4cbdcf538e8", "52fa85f205505f671f3d0d7b"]
    }
}

It gives me the following error when I try to do a GET on the document:

An exception of type 'System.IO.FileFormatException' occurred in MongoDB.Driver.dll but was not handled in user code
Additional information: An error occurred while deserializing the Values property of class API.Models.Record.Record: Cannot create an abstract class.

if I look at the database it saved it but its really funky looking:

anyone had any experience with dynamics and mongo?

解决方案

Update: dynamic is now supported by the v2.0 driver.

You can't use dynamic and MongoDB's C# driver. Here's a the jira ticket about it.

From the description:

We have not yet determined in which version we might add support for C# dynamic types. This ticket is a place where you can comment on the desirability of the feature and/or vote for it.
