Question

我想从SharePoint列表中获取最后一项，但由于我是SharePoint新手，因此我很难完成任何事情。首先，这个CAML API很难找到，然后我真的没有任何编程经验。

无论如何，这是我在ASPX页面中的逻辑。我想显示最后一项：

<html>

<head>
    <meta name="WebPartPageExpansion" content="full" />
    <meta name="ProgId" content="SharePoint.WebPartPage.Document" />

    <script runat="server" type="">
        protected void sevak(object sender, EventArgs e)
        string lastitem;
        try {
            using (SPSite objsite = new SPSite()) {
                using (SPWeb objWeb = objSite.OpenWeb(....)) {
                    SPList objList = objWeb.Lists["List"];
                    SPQuery objQuery = new SPQuery();
                    objQuery.Query = "<OrderBy><FieldRef Name='Number' Ascending='False'/></OrderBy><RowLimit>1</RowLimit>";
                    objQuery.Folder = objList.RootFolder;
                    SPListItemCollection colItems = objList.GetItems(objQuery);

                    if (colItems.Count>0) {
                        lastitem=colItems[0];
                    }
                }
            }
        }
        catch (Exception ex) { }

        return lastitem;
   </script>


   <SharePoint:CssLink runat="server"></SharePoint:CssLink>
   <SharePoint:ScriptLink runat="server" language="javascript" name="core.js"></SharePoint:ScriptLink>
</head>
<body>
    <form id="form1" runat="server">
    <h1>T-Site</h1>

    <p>
        <asp:Button runat="server" Text="Submit" id="Button1" OnClick="sevak" OnClientClick="javascript:window:alert('Your Request for a document number has been received');"></asp:Button>
    </p>
</body>
</form>
</html>

用于CAML查询使用U2U CAML查询构建工具，它非常易于使用

第二，你必须在安装了SharePoint的服务器上执行你的对象模型代码逻辑是正确的，但我看到你的语法有问题
