SharePoint Online - Managed Metadata - TermSets - Document Library

Is there a way to get all managed metadata fields and associated termsets/ terms of that field of a specific document library in SharePoint Online using CSOM?

I can get all the terms/ termset from term store. I can loop through term group, term set and terms. However, I cannot find a way to see which fields are associated to which terms.

If I go through all terms from term store, Throttling comes in to play.

If there is a way just to find terms that is associated to a given document library, please point me to the right direction.

Thanks

  • If anyone is having the same problem I was having... Here is what I've done....

    Field field = list.Fields.GetByInternalNameOrTitle("Your column Name");
clientContext.Load(field);
clientContext.ExecuteQuery();

var taxField = clientContext.CastTo<TaxonomyField>(field);
clientContext.Load(taxField);
clientContext.ExecuteQuery();

// Get the term set ID from the field's property
var termSetId = taxField.TermSetId;
//Get the term set by its ID
var taxonomySession = TaxonomySession.GetTaxonomySession(clientContext);
var termStore = taxonomySession.GetDefaultSiteCollectionTermStore();
var termSet = termStore.GetTermSet(termSetId);
var terms = termSet.GetAllTerms();
clientContext.Load(termSet);
clientContext.Load(terms);
clientContext.ExecuteQuery();

Term term = terms.GetByName("The value to assign");
clientContext.Load(term);
clientContext.ExecuteQuery();
TaxonomyFieldValue taxonomyFieldValue = new TaxonomyFieldValue();
taxonomyFieldValue.TermGuid = term.Id.ToString();
taxonomyFieldValue.Label = term.Name;
taxField.SetFieldValueByValue(item, taxonomyFieldValue);
