当我点击它时，如何在 Outlook 日历中获取选定的约会（ID？）？

Question

I can get a list of all calendar items but how can i pick the right one? How can i compare the IDs within the collection and the on screen clicked?

public void OnActionCallback(IRibbonControl control, bool isPressed)
        {
            _Outlook.Application oApp = null;
            oApp = new _Outlook.Application();
            var appointments = oApp.Session.GetDefaultFolder(OlDefaultFolders.olFolderCalendar).Items;

            foreach (AppointmentItem item in appointments)
            {
                JobTimeLine j = new JobTimeLine() 
                {
                    PostingDate = item.Start,
                    No = item.RequiredAttendees,
                    WorkTypeCode=item.Subject,
                    FromTime=item.Start.ToLocalTime(),
                    ToTime=item.End.ToLocalTime(),
                    ShipToName = null,
                    JobNo = item.ConversationTopic,
                    JobTaskNo = item.Body,
                    PlaceOfWork = "Büro",
                    Description= null,
                    Description2= null,
                    ShipToCostumerNo= "D20101",
                };

            MessageBox.Show("GlobalAppointmentID = " + item.GlobalAppointmentID + j.GetOutput());
            }
}

I am getting a collection but i need to pick exactly one item from it, which is clicked/selected/loaded in the outlook app.

The currently selected items in the Outlook explorer view can be retrieved by using the Selection property of the Explorer class which returns a Selection object that contains the item or items that are selected in the explorer window. The location of a selection in the explorer can be in the view list, the appointment list or task list in the To-Do Bar, or the daily tasks list in a calendar view. For more information, see the Location property.

private void DisplaySelectedItems()
{
    Outlook.Selection selection =
        Application.ActiveExplorer().Selection;
    for (int i = 1; i <= selection.Count; i++)
    {
        object myItem = selection[i];
    }
}

To get items displayed in the inspector windows in Outlook you may use the CurrentItem property of the Inspector class (see the ActiveInspector method of the Outlook Application class).

Also in the code I've noticed that a new Outlook Application instance is created:

_Outlook.Application oApp = null;
            oApp = new _Outlook.Application();

In the ribbon callbacks you can use the Application property of your add-in class or just access it by using the Globals static class in the following way:

Globals.ThisAddIn.Application
