How to append prefix on some specific values when deserializing

[diegosasw]

I am using YamlDotNet to deserialize a yml file into a custom object. For certain strings I'd like to append some prefix on the result.
For example, my custom class is:

class Metadata {
  public string Path {get; set; }
}

and my YML has:

path: image.jpg

and I want to append a given relative path so that when a path value is found it will be modified resulting in myMetadata.Path // /myPrefix/image.jpg when deserializing.

Something like .WithAttributeOverride but for values would be ideal. But I suspect I should do something with a custom Type converters although documentation at https://github.com/aaubry/YamlDotNet/wiki/Serialization.TypeConverters is empty and I couldn't manage to have anything working.

Any guide on whether this is possible would be much appreciated. Cheers!
