如何验证 SharePoint 列表项更新是否成功

Question

我正在尝试通过 InfoPath 表单更新 SharePoint 列表。输入开始日期 SelectedDAM，然后代码计算 6 个日期。必须在原始 SP 列表中更新新计算的日期。

下面的代码在调试模式下没有引发异常，甚至在生产中也是如此。我检查了 'jobs' 是否填充了数据，并且文件列表名称与它们的 SharePoint 名称一致。遗憾的是，当我之后查看 SharePoint 列表时，项目没有更新。

public void SetDAMButton_Clicked(object sender, ClickedEventArgs e)
    {
        string SelectedCEC = nav.SelectSingleNode("/my:mesChamps/my:DAMSection/my:CEC", this.NamespaceManager).Value;
        string SelectedDAM = nav.SelectSingleNode("/my:mesChamps/my:DAMSection/my:DAM", this.NamespaceManager).Value;

        //Query all jobs and dates from SharePoint List
        XmlDocument xmlDoc = new XmlDocument();
        XmlNode query = xmlDoc.CreateNode(XmlNodeType.Element, "Query", "");
        XmlNode viewFields = xmlDoc.CreateNode(XmlNodeType.Element, "ViewFields", "");

        query.InnerXml = "<Where>" +
                             "<Contains><FieldRef Name='CEC'/>" +
                             "<Value Type='Text'>" + SelectedCEC.Trim() + "</Value></Contains>" +
                         "</Where>";

        viewFields.InnerXml = "<FieldRef Name='ID' />" + 
            "<FieldRef Name='JRS_x0020_Avant' />"+ "<FieldRef Name='JRS_x0020_Pr_x00e9_vus' />"+ 
            "<FieldRef Name='JRS_x0020_Prevus_x0020_2' />"+ "<FieldRef Name='JRS_x0020_Avant_x0020_2' />"+
            "<FieldRef Name='JRS_x0020_Pr_x00e9_vus_x0020_3' />" + "<FieldRef Name='JRS_x0020_Avant_x0020_3' />";

        XmlNode listItems = sp.getListService().GetListItems(SPJobsListGlobal, null, query, viewFields, "10000000", null, null);

        //Extract jobs data to an internal list
        List<string[]> jobs = new List<string[]>();
        for (int i = 1; i != listItems.ChildNodes[1].ChildNodes.Count; i += 2)
        {
            string jobId = listItems.ChildNodes[1].ChildNodes[i].Attributes[0].InnerXml;
            string JRSAvant = listItems.ChildNodes[1].ChildNodes[i].Attributes[1].InnerXml; 
            string JRSPrevus = listItems.ChildNodes[1].ChildNodes[i].Attributes[2].InnerXml;
            string JRSPrevus2 = listItems.ChildNodes[1].ChildNodes[i].Attributes[3].InnerXml;
            string JRSAvant2 = listItems.ChildNodes[1].ChildNodes[i].Attributes[4].InnerXml;
            string JRSPrevus3 = listItems.ChildNodes[1].ChildNodes[i].Attributes[5].InnerXml;
            string JRSAvant3 = listItems.ChildNodes[1].ChildNodes[i].Attributes[6].InnerXml;
            jobs.Add(new string[] { jobId.Trim(), JRSAvant.Trim(), JRSPrevus.Trim(),JRSAvant2.Trim(), JRSPrevus2.Trim(), JRSAvant3.Trim(), JRSPrevus3.Trim() });
        }
        jobs.RemoveAt(jobs.Count - 1);

        //Update each item of SharePoint list with dates calculated from new DAM
        for(int i = 0; i != jobs.Count; i++)
        {
            XmlDocument doc = new XmlDocument();
            XmlElement batch = doc.CreateElement("Batch");
            batch.InnerXml = "<Method ID='1' Cmd='Update'>" +
                "<Field Name='ID'>" + SecurityElement.Escape(jobs[i][0]) + "</Field>" +
                "<Field Name='DateDebut'>" + SecurityElement.Escape(Convert.ToDateTime(SelectedDAM).AddDays(-validateJRS(jobs[i][1])).ToString("yyyy-MM-dd")) + "</Field>" +
                "<Field Name='DateFin'>" + SecurityElement.Escape(Convert.ToDateTime(SelectedDAM).AddDays(-validateJRS(jobs[i][1])).AddDays(validateJRS(jobs[i][2])).ToString("yyyy-MM-dd")) + "</Field>" +
                "<Field Name='Date_x0020_D_x00e9_but_x0020_2'>" + SecurityElement.Escape(Convert.ToDateTime(SelectedDAM).AddDays(-validateJRS(jobs[i][3])).ToString("yyyy-MM-dd")) + "</Field>" +
                "<Field Name='Date_x0020_Fin_x0020_2'>" + SecurityElement.Escape(Convert.ToDateTime(SelectedDAM).AddDays(-validateJRS(jobs[i][3])).AddDays(validateJRS(jobs[i][4])).ToString("yyyy-MM-dd")) + "</Field>" +
                "<Field Name='Date_x0020_D_x00e9_but_x0020_3'>" + SecurityElement.Escape(Convert.ToDateTime(SelectedDAM).AddDays(-validateJRS(jobs[i][5])).ToString("yyyy-MM-dd")) + "</Field>" +
                "<Field Name='Date_x0020_Fin_x0020_3'>" + SecurityElement.Escape(Convert.ToDateTime(SelectedDAM).AddDays(-validateJRS(jobs[i][5])).AddDays(validateJRS(jobs[i][6])).ToString("yyyy-MM-dd")) + "</Field>" +
                "</Method>";
            sp.UpdateListItems(SPJobsListGlobal, batch);
        }

为什么不起作用？我可以添加任何额外的行来确认更新吗？

Answer 1

要确认更新，您可以检查 Lists.UpdateListItems 的 return 值，这是一个包含更新状态的 XmlNode。

来自MSDN：

Return value

An XMLDATA fragment in the following form that shows the status of each method block posted through the updates parameter and that can be assigned to a System.Xml.XmlNode object. For items successfully updated, a row fragment is returned with the updated row values.
