Passing C# field through javascript and back into C# results in null

[SnowSnakz]

Here is my setup:

I plan to use JavaScript as the language for modding my game, I currently have it setup to create a javascript context with 3 variables: log, mod and require, require isn't being used yet...

mod is a C# object with the field I am trying to use.
log is also a C# object with functions that redirect to log4net, (mainly info(string format, object[] objs))

Here is the issue, in my javascript file I have:

log.info("Hello from {0}!", [mod.display_name]);

Which results in:

Hello from !

Even though mod's C# object has the field display_name set to "sandbox"
I even checked with the debugger, the C# instance of mod is correct, I debugged the C# function for log.info and noticed that mod.display_name was evaluating to null before being passed through the function. Why is this happening? And how can I fix it?

I think only public properties will go through to JavaScript. Obviously if your displayr_name is null then that is your problem.

The field is both public and not null.

I used the debugger in VS to check, the field is public and the value is "sandbox", when I pass it through JavaScript it comes out as null...

Try to reduce this to a simple example that you can post here.

I can't even seem to setup the project anymore, Visual Studio just crashes when I load my pre-existing project and when I install the NuGet package, the Noesis.Javascript namespaces don't exist.... This has to be a bug with my Visual Studio installation.

(I haven't touched this project for a few days)

Reguardless, I was using fields, and I just now noticed that you said "properties"... So if I am not mistaken by "property" you mean specifically this:

public Type PropertyName { get; set; }

And not this:

public Type FieldName;

Yes, I don't think fields are supported. You get null rather than an error when a property does not exist. (This is convenient sometimes, and not other times. Your object can also store arbitrary new properties, if I remember correctly.)
