我为选定的附件创建了一个Outlook插件,以获取附件的详细信息.它在Outlook 2010中运行良好.但是当我为Outlook 2016构建它时,它变为null.

以下是ThisAddIn.cs中的代码: -

 private void ThisAddIn_Startup(object sender, System.EventArgs e)
        {
            System.Reflection.Assembly assemblyInfo = System.Reflection.Assembly.GetExecutingAssembly();
            Uri uriCodeBase = new Uri(assemblyInfo.CodeBase);
            string Location = Path.GetDirectoryName(uriCodeBase.LocalPath.ToString());
            var path = Location.Split(new string[] { "bin" }, StringSplitOptions.RemoveEmptyEntries);
            var rootDir = path[0].ToString();
            var forPermissionsRootDirectory = Path.GetDirectoryName(rootDir);
            SetPermissions(forPermissionsRootDirectory);

            app = this.Application;
            app.AttachmentContextMenuDisplay += new Outlook.ApplicationEvents_11_AttachmentContextMenuDisplayEventHandler(app_AttachmentContextMenuDisplay);//attach Attachment context Menu Event//

        }

 void app_AttachmentContextMenuDisplay(Office.CommandBar CommandBar, Outlook.AttachmentSelection selection)
        {
            selectedAttachment = selection;
            RibbonUI.InvalidateControlMso("ContextMenuAttachments");//will get XML file data//

        }

这是AttachmentContextMenu.cs中的代码: -

public void OnOpenMyMotionCalendarButtonClick(Office.IRibbonControl control)
        {
            Outlook.AttachmentSelection selection = …
