连接到Outlook日历中使用互操作的C＃ [英] Connect to Outlook calendar from C# using Interop

问题描述

好吧，我尝试使用下面的代码连接到从C＃Outlook日历：

Ok I am trying to connect to an Outlook calendar from C# using the following code:

using Outlook = Microsoft.Office.Interop.Outlook;

Outlook.Application msOutlook = new Outlook.Application();
Outlook.NameSpace ns = msOutlook.GetNamespace("MAPI");
Outlook.MAPIFolder folder = ns.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderCalendar);

foreach (Outlook.MAPIFolder subfolder in folder.Folders)
{
    MessageBox.Show(subfolder.Name);
}

不过，尽管有两个日历，一段代码上面并没有看到！任何

However, despite having two Calendars, the piece of code above doesn't see any!

我想我可能有更多的运气与下面的代码：

I'm thinking I may have more luck with the below code:

Outlook.MAPIFolder folder = ns.GetFolderFromID("CalendarName", Type.Missing);

但这抛出以下异常：

But this is throwing the the following exception:

无法打开该项目。请再试一次。

Could not open the item. Try again.

我猜日历ID是比它的名字以外的东西。

I'm guessing the calendars ID is something other than it's name.

我在做什么错了？

另外，我使用C＃4在.NET 4中和Outlook 2010。

Also, I'm using C#4 with .Net 4 and Outlook 2010.

推荐答案

是MAPI命名空间中两个日历？如果你遍历命名空间，看看其他的有一个日历：

Are both calendars in the MAPI namespace? What if you loop through the namespaces to see if other ones have a calendar:

Outlook.Application msOutlook = new Outlook.Application();
Outlook.NameSpace session = msOutlook.Session;
Outlook.Stores stores = session.Stores;
foreach (Outlook.Store store in stores)
{
    Outlook.MAPIFolder folder = store.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderCalendar);

    MessageBox.Show(folder.Name);
}
