This is an example of a model that I'm trying to use.
MongoDb Document:
{
"_id": {
"$oid": "65d96a518c225137f2d2aee4"
},
"Name": "Test 1",
"Places": [
"Place 1",
"Place 2"
],
"LoginInfo": {
"Website": "string",
"UserName": "string",
"Password": "string"
}
}
C# Class
[Collection("tests")] [BsonIgnoreExtraElements] public class Test{ public ObjectId Id { get; set; } public string? Name { get; set; } public List<string>? Places { get; set; } [BsonIgnoreIfNull] public LoginInfo LoginInfo { get; set; } = null!; }
LoginInfo Class
public class LoginInfo{ public string? Website { get; set; } public string? UserName { get; set; } public string? Password { get; set; } }
A large driver for me selecting this database type was the flexibility of fields on Documents. Currently if I do not provide a "LoginInfo" property on each of my documents, then it returns:
System.Collections.Generic.KeyNotFoundException: Element 'LoginInfo' not found.
If I provide even and empty object named "LoginInfo" then it works and correctly maps null to the properties which I've defined as null. I have tried making the property nullable, Ignoring extra elements, ignoring the bson if null, using the BsonClassMap, specifiying the BsonElement and even initializing a new LoginInfo if its null. None of which work.
Below is the package versions I'm using as well
<Project Sdk="Microsoft.NET.Sdk.Web"> <PropertyGroup> <TargetFramework>net8.0</TargetFramework> <Nullable>enable</Nullable> <ImplicitUsings>enable</ImplicitUsings> </PropertyGroup> <ItemGroup> <PackageReference Include="MongoDB.Driver" Version="2.24.0"/> <PackageReference Include="MongoDB.EntityFrameworkCore" Version="7.0.0-preview.1"/> <PackageReference Include="Microsoft.EntityFrameworkCore" Version="7.0.14"/> <PackageReference Include="Swashbuckle.AspNetCore.Swagger" Version="6.5.0"/> <PackageReference Include="Swashbuckle.AspNetCore" Version="6.5.0"/> </ItemGroup> </Project>
