我正在尝试使用在 SharePoint 2013 服务器中部署的自定义 WCF Web 服务在 SharePoint 2013 中创建一个新术语集。我写了下面的代码来创建术语集。
SPSecurity.RunWithElevatedPrivileges(delegate()
{
using (Impersonator imp = new Impersonator("Username", "Domain", "Password"))
{
using (SPSite site = new SPSite("http://server:8002/sites/site/"))
{
site.AllowUnsafeUpdates = true;
TaxonomySession session = new TaxonomySession(site);
TermStore termStore = session.TermStores["Managed Metadata Service"];
var termStoreAdmin = termStore.TermStoreAdministrators.Where(obj => obj.PrincipalName.Contains("domain\\username")).FirstOrDefault();
if (termStoreAdmin == null)
termStore.AddTermStoreAdministrator("domain\\username");
Group group = termStore.GetGroup(new Guid(groupGuid));
if (group != null && !string.IsNullOrEmpty(termSetName))
{
TermSet termset = group.TermSets.FirstOrDefault(obj => obj.Name.Equals(termSetName));
if (termset == null)
{
termset = group.CreateTermSet(termSetName);
termSetGuid = termset.Id.ToString();
}
SetupNavTermSet(termset, session, site.OpenWeb());
}
termStore.CommitAll();
}
}
});
我使用肥皂消息从 silverlight 代码调用此方法。在调用此代码时,我在执行group.CreateTermSet(termSetName);
行时遇到异常。
错误是:
Error Message : Value cannot be null.

有没有人遇到这个问题和解决方案?
