Documentation for Parsing Dotnet Resources

[utkonos]

Can someone point to documentation for the structure of a dotnet resource: header and data?

I am able to save a resource using ILSpy here:

But then I would like to be able to parse the resulting file. There is clearly a header and then PNG data in this example, but I would like to find the documentation for this format in general. Any pointers would be appreciated.

I'm not sure if any documentation exists.
The class System.Resources.ResourceReader implements the logic to read these files. ILSpy uses its own modified copy of this logic to avoid the security issues with deserialization.

@dgrunwald thanks for the quick answer. I now have a few sources of information and some implementations.

This is the class you're referring to:
https://learn.microsoft.com/en-us/dotnet/api/system.resources.resourcereader

These are two source code files I can look at as well as the implementation in ILSpy:
https://github.com/microsoft/referencesource/blob/master/mscorlib/system/resources/resourcewriter.cs
https://github.com/microsoft/referencesource/blob/master/mscorlib/system/resources/resourcereader.cs

I will also dig into the source code for Mono and see if there is an implementation of the same there.
