如何获取不是收件箱子文件夹的MAPI文件夹？

Question

有许多问题询问如何在Outlook中获取文件夹，但我看到的所有答案都假设此文件夹嵌套在收件箱文件夹下。即使Microsoft's documentation也假设：

B

假设我的邮箱根目录下有以下文件夹：

• private void SetCurrentFolder() { string folderName = "TestFolder"; //THIS STATEMENT ASSUMES WE'RE LOOKING IN THE INBOX Outlook.MAPIFolder inBox = (Outlook.MAPIFolder) this.Application.ActiveExplorer().Session.GetDefaultFolder (Outlook.OlDefaultFolders.olFolderInbox); try { this.Application.ActiveExplorer().CurrentFolder = inBox. Folders[folderName]; this.Application.ActiveExplorer().CurrentFolder.Display(); } catch { MessageBox.Show("There is no folder named " + folderName + ".", "Find Folder Name"); } }
• Inbox
• Drafts

如何将MyCustomFolder（不是收件箱的子文件夹）作为MyCustomFolder或MAPIFolder？

Answer 1

假设该文件夹是收件箱文件夹的对等方，您可以获取收件箱，然后上一层，然后检索相关文件夹：

Outlook.MAPIFolder inBox = (Outlook.MAPIFolder)
        this.Application.ActiveExplorer().Session.GetDefaultFolder
        (Outlook.OlDefaultFolders.olFolderInbox);
Outlook.MAPIFolder rootFolder = (Outlook.MAPIFolder)inBox.Parent;
Outlook.MAPIFolder myFolder = rootFolder.Folders["MyCustomFolder"];
