MongoDB C# Driver Serialization with dynamic objects
.net, c#, dynamic, mongodb, mongodb-.net-driver
Solution
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.
Problem
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?
