使用 Interop 从 C# 连接到 Outlook 日历

好的，我尝试使用以下代码从 C# 连接到 Outlook 日历：

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);
}

但是，尽管有两个日历，上面的代码片段看不到任何日历！

我想我可能对下面的代码有更多的运气：

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

但这引发了以下异常：

无法打开该项目。再试一次。

我猜日历 ID 不是它的名称。

我做错了什么？

另外，我将 C#4 与 .Net 4 和 Outlook 2010 一起使用。

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);
}

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

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

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

But this is throwing the the following exception:

Could not open the item. Try again.

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

What am I doing wrong?

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

两个日历都在 MAPI 命名空间中吗？如果您循环遍历命名空间以查看其他命名空间是否有日历会怎样：

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);
}

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);
}
