我在使用LINQ查找記錄並更新找到的記錄時遇到了問題。即使這個超級簡單的版本也不行。有錯誤是完全通用的(見下文)。CRM 2011 LINQ更新錯誤
下面是代碼,我從查詢中得到一個實體,我無法更新它。
var account = orgContext.CreateQuery("account").First(c => c["name"] == "apple");
account["name"] = "Microsoft";
orgContext.UpdateObject(account);
orgContext.SaveChanges(); ///ERROR HERE

您是否嘗試過使用'account.name =「Microsoft」;'? – 2012-08-10 01:52:16
你可以發佈其他的例外細節嗎?它在「內部例外」中刪除 - 是否沒有更多細節要添加? – glosrob 2012-08-10 14:45:22
