Sharepoint 2013 以编程方式将客户端Web部件（应用程序部件）添加到sharepoint页面

我需要将提供商托管应用程序中的客户端Web部件添加到其部署到的主机Web中的页面上。我曾尝试使用客户端对象模型的有限Web部件管理器来实现这一点，但这仅适用于属于.dwp或.WebPart文件的xml数据。我使用了下面的代码。是否有解决方法，从站点获取应用程序部件文件并将其添加到Sharepoint页面

        ClientContext clientconteext = new ClientContext("My Server URL");
        Microsoft.SharePoint.Client.File page = clientconteext.Web.GetFileByServerRelativeUrl("/sites/MySite/SitePages/Home.aspx");

        clientconteext.Load(clientconteext.Web);
        clientconteext.Load(page);
        clientconteext.ExecuteQuery();
        LimitedWebPartManager lwp= page.GetLimitedWebPartManager(PersonalizationScope.Shared);
        string webpartxml = "<?xml version=\"1.0\" encoding=\"utf-8\"?><Elements xmlns=\"http://schemas.microsoft.com/sharepoint/\"><WebPartPages:ClientWebPart runat=\"server\" FeatureId=\"5b1a14dd-8dbe-4963-8612-e7918e7fbc9a\" ProductWebId=\"5b1a14dd-8dbe-4963-8612-e7918e7fbc9a\" WebPartName=\"HomePageAppPart\" Title=\"Home App Part\" Description=\"WebPart Description\" WebPart=\"true\"></WebPartPages:ClientWebPart></Elements>";
        WebPartDefinition wpd = lwp.ImportWebPart(webpartxml);
        lwp.AddWebPart(wpd.WebPart, "Right", 1);
        clientconteext.ExecuteQuery();

ClientContext ClientContext=newclientcontext（“我的服务器URL”）；
Microsoft.SharePoint.Client.File page=ClientContext.Web.GetFileByServerRelativeUrl（“/sites/MySite/SitePages/Home.aspx”）；
加载（clientcontext.Web）；
clientcontext.Load（第页）；
ClientContext.ExecuteQuery（）；
LimitedWebPartManager lwp=page.GetLimitedWebPartManager（PersonalizationScope.Shared）；
字符串webpartxml=“”；
WebPartDefinition wpd=lwp.ImportWebPart（webpartxml）；
lwp.AddWebPart（wpd.WebPart，“右”，1）；
ClientContext.ExecuteQuery（）；

这是您需要执行的步骤

您需要将应用程序部件从浏览器添加到任何页面

在“Web部件属性”窗格中，展开“高级”部分，将“导出模式”设置为“导出所有数据”，然后单击“确定”

在应用程序部件中，单击web部件标题旁边的下拉箭头，然后导出

将.webpart文件复制到项目（例如：模板文件夹）

添加此方法以创建发布页面并将应用程序部件添加到其中
