这就是我的做法；

Outlook.Application myApp = new Outlook.Application();
Outlook.NameSpace mapiNameSpace = myApp.GetNamespace("MAPI");
Outlook.MAPIFolder myInbox = mapiNameSpace.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderInbox).Folders["QC"];

这应该会将所有邮件带入收件箱.然后调用；

This should bring all mails in Inbox. Then call;

Outlook.MailItem mailItem = myInbox.Items[1];   

此mailItem 包含您需要的所有属性.

This mailItem contains all the attributes you need.

说明:mailFolder.Items[1] 是一个 Outlook.Items 对象，它没有您需要的属性.您需要将其转换为 Outlook.MailItem 对象以实现此目的.

Explanation: The mailFolder.Items[1] is an Outlook.Items object which has no attributes you require. You need to cast it to an Outlook.MailItem object to achieve this.
