MSDN说这个的在MAPIFolder接口（Outlook中的编程与WPF）：

MSDN says this of the MAPIFolder interface (Outlook programming with WPF):

此接口德precated;不要   使用该接口。而是使用   接口文件夹访问所有的方法，   在COM属性和事件成员   目标文件夹。

This interface is deprecated; do not use this interface. Instead use the interface Folder to access all method, property, and event members of the COM object Folder.

我想获得草稿文件夹，如下所示：

I am trying to get the Drafts folder like so:

Outlook.MAPIFolder oFolder = olNS.GetDefaultFolder（Outlook.OlDefaultFolders.olFolderDrafts）;

我要如何做上述不使用MAPIFolder（这是德precated）？ 我想我不明白MSDN是说（使用文件夹界面访问所有的方法等）

How do I do the above without using the MAPIFolder (which is deprecated)? I guess I don't understand what MSDN is saying (using the Folder interface to access all method etc)

推荐答案

您只需将其转换为Outlook.Folder，即

You simply cast it to Outlook.Folder, i.e.

Outlook.Folder oFolder = (Outlook.Folder) olNS.GetDefaultFolder( Outlook.OlDefaultFolders.olFoderDrafts)

不可否认，在MSDN比较混乱那里。你可以把文件夹界面围绕MAPIFolder的包装中，对事件的其他支持。

Admittedly, the MSDN is rather unclear there. You can think of the Folder interface as a wrapper around the MAPIFolder, with additional support for events.

在我的阿里纳斯，我想借此事与一粒盐整个'pcated德$ P $。我敢打赌MAPIFolder在这里留下来，至少有一对夫妇多个版本的Outlook。

As I sidenote, I would take the whole 'deprecated' thing with a grain of salt. I'd bet MAPIFolder is here to stay, at least for a couple more versions of Outlook.
