如何使用.Net创建Outlook PST文件？

Question

我正在编写一个可以操作Outlook数据的应用程序.我想首先备份这些数据,并希望我可以循环浏览联系人/日历项目等,并将它们写入PST文件.

如何使用.Net将1个或多个Outlook文件夹的内容写入PST？[vb或c#无所谓]

Answer 1

我能够从互联网和MSDN文档的各种示例中将这些代码拼凑在一起.这将允许您选择Outlook高级文件夹,并将备份下面的所有文件夹.在我的情况下,我实际上并不想要邮件文件夹,所以我排除它们.

        Const BACKUP_PST_PATH As String = "C:\backup.pst"    

        Dim oFolder As Outlook.MAPIFolder = Nothing
        Dim oMailbox As Outlook.MAPIFolder = Nothing

        Dim app As New Outlook.Application()
        Dim ns As Outlook.NameSpace = app.GetNamespace("MAPI")
        Try
            //if the file doesn not exist, outlook will create it
            ns.AddStore(BACKUP_PST_PATH)
            oFolder = ns.Session.Folders.GetLast()
            oMailbox = ns.PickFolder()

         For Each f As Outlook.Folder In oMailbox.Folders
            If f.DefaultItemType <> Microsoft.Office.Interop.Outlook.OlItemType.olMailItem And f.FolderPath <> oFolder.FolderPath Then
                f.CopyTo(oFolder )
            End If
        Next

        ns.RemoveStore(oFolder)

        Catch ex As Exception
            ns.RemoveStore(oFolder)
            IO.File.Delete(BACKUP_PST_PATH)
            Throw ex
        End Try
