我想在CSOM中设置Sharepoint 2013 TaxonomyField的值,但是当我执行最后的context.ExecuteQuery()
时,在taxField.Update()
之后抛出异常读取'Microsoft.SharePoint.Client.Runtime.dll中发生类型'Microsoft.SharePoint.Client.ServerException'的第一次机会异常其他信息:值不能为空。参数名称:termId'。一切都很好,它找到了这个词,我没有想法。当通过CSOM添加分类标准值异常“值不能为null。ParamterName:termId”抛出
public void AddTaxonomyFieldValue(ClientContext context, ListItem item, string destinationColumn, IEnumerable<string> terms, Guid termGroupId, Guid termSetId, int lcid)
{
var taxonomySession = TaxonomySession.GetTaxonomySession(context);
var store = taxonomySession.TermStores.GetByName("Managed Metadata Service2");
var group = store.GetGroup(termGroupId);
var set = group.TermSets.GetById(termSetId);
var existingTerms = set.GetAllTerms();
var field = item.ParentList.Fields.GetByInternalNameOrTitle(destinationColumn);
var taxField = context.CastTo<TaxonomyField>(field);
context.Load(existingTerms, et => et.Include(t => t.Labels.Include(l => l.Value, l => l.Language), t => t.Id, t=> t.PathOfTerm, t => t));
context.ExecuteQuery();
var fieldTermValues = new Collection<Term>();
foreach (var term in terms)
{
var lmi = new LabelMatchInformation(context);
lmi.TermLabel = term;
// Find existing term
var existingTerm =
existingTerms.FirstOrDefault(t => t.Labels.Any(l => l.Language == lcid && l.Value == term));
if (null == existingTerm)
{
// create new term
existingTerm = set.CreateTerm(term, lcid, new Guid());
set.TermStore.CommitAll();
context.Load(existingTerm);
context.ExecuteQuery();
}
fieldTermValues.Add(existingTerm);
}
// set taxonomy field
taxField.SetFieldValueByCollection(item, fieldTermValues, lcid);
taxField.Update();
// Exception Thrown Here
context.ExecuteQuery();
}
编辑1: 我只注意到我在foreach循环创建的分类项具有唯一标识符==“00000000-0000-0000-0000-000000000000”它从SharePoint看时现场。所以我在想我的问题在那里。
