完全なエラーは次のとおりです。

Invalid data has been used to update the list item. The field you are trying to update may be read only.

基本的に、Sharepointのカレンダーイベントを更新しようとしています。

まず、次のようになります。

ClientContext clientContext = new ClientContext(deptUrl);
Web web = clientContext.Web;
List list = web.Lists.GetByTitle(deptCal);
clientContext.Load(list);

CamlQuery query = new CamlQuery();
query.ViewXml = "<View><Query><Where><IsNull><FieldRef Name='EndDate' /></IsNull></Where></Query><RowLimit>1</RowLimit></View>";

ListItemCollection allEventIds = list.GetItems(query);

clientContext.Load(allEventIds, 
items => items.Include(
     item => item["EventID"],
     item => item["EventDate"],
     item => item["EndDate"]
));

clientContext.ExecuteQuery();

ループが続きます：

foreach (var item in allEventIds)
{
   Console.Write("EventId: {0} StartDate: {1}\n", item.FieldValues["EventID"], item.FieldValues["EventDate"]);

                if (item.FieldValues.ContainsKey("EventDate"))
                {
                    object objValue = item.FieldValues["EventDate"];
                    if (objValue != null)
                    {
                        clientContext.Load(item);                        
                        DateTime endDate = DateTime.Parse(objValue.ToString());
                        item["EndDate"] = endDate; //Updated this!

                    }
                }
                item.Update();

            }

そして最後に：

clientContext.ExecuteQuery();

ListItem内の他のitem[x]を更新しようとすると、正常に機能します。「EndDate」を更新しようとすると。次のエラーが発生します。

Sharepointはこのように配線されています。EndDateを単独で更新すると、上記のエラーが発生します。解決策は、EventDateとEndDateを一緒に更新することです。

DateTime startDate = DateTime.Parse(objValue.ToString());
item["EventDate"] = startDate;
item["EndDate"] = startDate; //Or Any other date you want to set to.
