Can I trigger an exception on missing fields?

[stdNullPtr]

Hey, so I currently have a yaml with 3 fields, doesn't matter what their names or values.
And let's say I have an object to deserialize to that has 4 fields. I would expect that if the 4th field is not present in the yaml, I would get an exception - but that's not the case.
Any ideas?

Also, can I generate a comment for every field, during serialization? For example, adding a comment in the field with YamlMember or something?

You wouldn’t get an exception when your yaml has 3 fields and your class has 4. You would only get an exception a field in your yaml doesn’t exist on your class.

You should be able to use the yamlmember attribute on fields and properties to add comments in your yaml without issue.

So you would have to check after parsing if the fields are populated? I thought there would be a more elegant approach.

Can you please point me to the relevant documentation about the yamlMember attributes? Thanks!

There’s pretty good comments on the yamlmemberattribute that you can review. They should also show up in intelligence in visual studio.

I don’t think there’s any formal documentation on it.

You are right the comments are good, thank you

You would also need to check if the fields get set by yourself. One potential reliable solution would be to use properties with a setter that keep track when the property was set.

Thanks that sounds like an idea
