从 C# 中的 GUID 获取 SharePoint 在线列表名称

Question

Why am I getting this error when I run the code below?

Microsoft.SharePoint.Client.PropertyOrFieldNotInitializedException: 'The property or field 'Title' has not been initialized. It has not been requested or the request has not been executed. It may need to be explicitly requested.'

 public  string getInternalNameOfList(string siteURL, Guid listGUID)
    {
        string listName = "";
        ClientContext clientContextD = new ClientContext(siteURL);
        clientContextD.Credentials = _credentials;
        ListCollection listCollectionD = clientContextD.Web.Lists;

        clientContextD.Load(listCollectionD, lists => lists.Include(list => list.Id , list => list.Title, list => list.SchemaXml, list => list.TemplateFeatureId, list => list.Fields));
        clientContextD.ExecuteQuery();

        Web oWebsiteD = clientContextD.Web;

        clientContextD.ExecuteQuery();
        listName = clientContextD.Site.RootWeb.Lists.GetById(listGUID).Title;
        return listName;
    }

Try to change your code to the below:

List list = web.Lists.GetById(listGUID);
clientContextD.Load(list);
clientContextD.ExecuteQuery();
listName = list.Title
