这是完整的错误:
Invalid data has been used to update the list item. The field you are trying to update may be read only.
我基本上是尝试更新 Sharepoint 中的日历事件。
首先我得到以下信息。
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();
接着是一个循环:
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();
}
然后最后:
clientContext.ExecuteQuery();
如果我尝试更新 ListItem 中的任何其他项目[x],工作正常。当我尝试更新“结束日期”时。我收到以下错误:

最佳答案
Sharepoint 是这样连线的。当你自己更新 EndDate 时,它会给你一个上面列出的错误。解决方案是同时更新 EventDate 和 EndDate。
DateTime startDate = DateTime.Parse(objValue.ToString());
item["EventDate"] = startDate;
item["EndDate"] = startDate; //Or Any other date you want to set to.
关于sharepoint - 更新 EndDate 导致 "Invalid data has been used to update the list item",我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/10079961/
