Question

我在生产中有一个名为Documents的文档库。我写了一个计时器作业，用于根据库中的列发送电子邮件。

在开发环境中一切都很好但是prod中的计时器工作给了我例外。有什么想法吗？

        Entering monitored scope (Timer Job Corporate Policies - Reminder Emails)

作业定义的执行方法CorporatePolicyReminders.DailySchedule（ID 3586f4d2-1bc1-4770-b5b8-4c2c578ee8d5）引发了异常。更多信息包括在下面。对象引用未设置为对象的实例。

异常堆栈跟踪：
在CorporatePolicyReminders.CorporatePolicyReminders.SendCorporateReminder（SPWeb web）
在CorporatePolicyReminders.DailySchedule.Execute（Guid contentDbId）
在Microsoft.SharePoint.Administration.SPTimerJobInvokeInternal.Invoke（SPJobDefinition jd，Guid targetInstanceId，Boolean isTimerService，Int32＆amp; result）

离开监控范围（计时器工作公司政策 - 提醒电子邮件）。执行时间= 364.288198639771

SendCorporateReminers Method

 public void SendCorporateReminder(SPWeb web)
{
    SPList lstComplaint = Helper.GetList(web, "Documents", Helper.ListType.Library);

    if (lstComplaint != null)
    {
        string query = "<Where><Eq><FieldRef Name='DocFormat' /><Value Type='Choice'>Policy</Value></Eq></Where>";
        SPListItemCollection colRecords = Helper.ExecuteQueryRecursive(lstComplaint, query, null, 2000);

        if (colRecords != null && colRecords.Count > 0)
        {
            foreach (SPListItem item in colRecords)
            {

                DateTime Expires = Helper.GetSPFieldDateTimeValue(item, "Expires");
                String Title = Helper.GetSPFieldTextValue(item, "Title");
                SPFieldUserValueCollection userResp = Helper.GetUsers(item, "Contact");
                TimeSpan totaldays = DateTime.Now.Date - Expires.Date;
                Int32 days = totaldays.Days;
                String emailtemplatekeyA = "AEmail" + days.ToString();
                String emailtemplatekeyB = "BEmail" + days.ToString();
                String respToEmail = String.Empty;

                    {
                        if (!string.IsNullOrEmpty(respToEmail))
                            respToEmail += ",";
                        respToEmail += user.User.Email;
                    }
                }
                HandleEmails handleEmail = new HandleEmails();

我找到了问题并解决了它。其用户标识不再有效的人是联系文档的人（他在我创建计时器作业的库的联系人列中）。因此，只要计划读取文档的“联系人”列，计时器作业就会抛出异常（对象引用未设置为对象的实例。）我通过修改我的代码如下所示，并从该列中删除了该人。

    Helper.WriteUlsInformation("Item processing:" + i.ToString(), TraceSeverity.Verbose);
                    DateTime Expires = Helper.GetSPFieldDateTimeValue(item, "Expires");
                    Helper.WriteUlsInformation("Expires:" + Expires.ToString(), TraceSeverity.Verbose);
                    String Title = Helper.GetSPFieldTextValue(item, "Title");
                    Helper.WriteUlsInformation("Title:" + Title, TraceSeverity.Verbose);
                    SPFieldUserValueCollection userResp = Helper.GetUsers(item, "Contact");
                    Helper.WriteUlsInformation("UserResp read" , TraceSeverity.Verbose);
                    TimeSpan totaldays = DateTime.Now.Date - Expires.Date;
                    Int32 days = totaldays.Days;
                    Helper.WriteUlsInformation("Days:"+ days.ToString(), TraceSeverity.Verbose);
                    String emailtemplatekeyA = "AEmail" + days.ToString();
                    String emailtemplatekeyB = "BEmail" + days.ToString();
                    String respToEmail = String.Empty;
