Goal:

The ability to create/update records using CSV into Umbraco and other data sources in the future but for now just CSV.

Problem:

One of the document types I'm trying to import into has a dropdown list which doesn't like the text been stored.

Found solution to that issue at https://our.umbraco.com/forum/umbraco-8/96101-umbraco-8-contentservice-and-dropdown-list#comment-306917

Which doing JsonConvert.SerializeObject(new[] { "My Value" }); is totally fine but how would I know when to serialise the object for the property? How can I differentiate it from plain textbox etc?

I'm getting a list of all the children from the parent like:

var children = Umbraco.Content(parentGuid)?.Children ?? null;

Once looping through the CSV rows then I'll check to see if I can find the child using:

var request = contentService.GetById(foundChild.Id);

Then I can use properties field from request to see if it's matches properties then call request.SetValue( ... )

The only thing I can think of is to perform an if statement on the request.Properties.PropertyType.PropertyEditorAlias is equal to Umbraco.DropDown.Flexible and then serialise that.

If you have a better solution, please let me know. Thanks.
