我在将 sharepoint listviewwebparts 添加到 Web 部件页面时遇到问题。我想用 C# 以编程方式完成它。我已经制作了页面，但添加 listviewwebpart 不起作用。代码如下。

   private void addListViewWebPart(SPFeatureReceiverProperties properties, String _listName)
        {
            using (SPWeb _web = properties.Feature.Parent as SPWeb)
            {
                SPList _list = _web.Lists.TryGetList(_listName);

                if (_list != null)
                {
                    ListViewWebPart _webPart = new ListViewWebPart();

                    _webPart.ZoneID = "Left";
                    _webPart.ListName = _list.ID.ToString("B").ToUpper();
                    _webPart.ViewGuid = _list.Views[0].ID.ToString("B").ToUpper();

                    SPWebPartCollection _webPartColl = _web.GetWebPartCollection("Default.aspx", Storage.Shared);
                    System.Guid _guid = _webPartColl.Add(_webPart);
                }
            }
        }

有人知道它为什么不工作吗？

提前致谢。

【解决方案1】：

您将需要使用SPLimitedWebPartManager 及其AddWebPart 方法。

此博客中有一个示例。：Add Web Part programmatically using SPLimitedWebPartManager。

感谢您的快速回复。但我有一个问题。 XmlUrlResolver _xmlResolver = new XmlUrlResolver();不工作，它不把它作为一个功能重新调整？难道我做错了什么？提前致谢
splimitedwebpartmanager 对我也不起作用......你知道这是为什么吗？提前致谢

以下网站对演示如何将 Web 部件添加到页面非常有帮助。它包括有关如何添加开箱即用 Web 部件和自定义 Web 部件的示例。来源：https://www.sharepointdiary.com/2012/08/how-to-add-web-parts-to-the-page-programmatically.html

        public static string AddListViewWebPartToPage(SPWeb web, 
                                                     string pageUrl, //full or relative

                SPLimitedWebPartManager WebPartMgr = web.GetLimitedWebPartManager(pageUrl, PersonalizationScope.Shared);

                //Check for existing web part with same title first
                //Added this to ensure that I don't add the same web part multiple times, especially if this is used in a feature activate function.
                foreach (Microsoft.SharePoint.WebPartPages.WebPart wp in WebPartMgr.WebParts)
                {
                    if (wp.Title == WPTitle)
                    {
                        return "WebPart with title of [" + WPTitle + "] already exists.";
                    }
                }

                //Get the object of the list of which we are creatin the list viewer webpart
                SPList list = web.Lists[ListName];
                ListViewWebPart oListViewWP = new ListViewWebPart();

                oListViewWP.ChromeType = chromeType;

                oListViewWP.ListName = list.ID.ToString("B").ToUpper();
                oListViewWP.ViewGuid = list.DefaultView.ID.ToString("B").ToUpper();

                //Define the zone in which webparts need to be added
                WebPartMgr.AddWebPart(oListViewWP, wpZone, 3);

            }
            catch (Exception ex)
            {

                return ex.ToString();

            }
            return "";

        }

    }
}
