Office.Interop.Outlook访问子文件夹 [英] Office.Interop.Outlook accessing sub-folders

问题描述

我正在编写一个使用Microsoft Outlook库访问某些文件夹的应用程序。我有一个问题，我可以打开命名空间并获取默认的收件箱文件夹，但每当我尝试访问基础文件夹时，我收到错误：

I am writing an application that uses Microsoft Outlook libraries to access some folders. I have a problem where I can open up the namespace and get the default Inbox folder but whenever I try to access the underlying folders I get the error:

[System.Runtime.InteropServices.COMException]	{"Interface not registered (Exception from HRESULT: 0x80040155)"}	

我能够获得 unreadItemcounts 并查看收件箱的属性。我使用的代码是：

I am able to get unreadItemcounts and view the properties of the Inbox. The code that I am using is:

appOutlook = new Outlook.Application();                    
nsOlApp = appOutlook.GetNamespace("MAPI");
nsOlApp.Logon(Type.Missing,Type.Missing, true, true);
// nsOlApp.Logon(Type.Missing, Type.Missing, Type.Missing, Type.Missing);
oFolder = nsOlApp.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderInbox);
foreach (Outlook.MAPIFolder fldr in oFolder.Folders)
{
    MessageBox.Show(fldr.Name.ToString());
} 

还有其他人有这个问题吗？



我已经成功注册了ole32.dll，并且必须使用Outlook库，因为我需要访问特定应用程序的收件箱中的子文件夹。



谢谢

Has anyone else had this problem?

I have registered ole32.dll successfully and must use Outlook libraries as I need to access sub-folders int he inbox for a particular application.

thanks

推荐答案

以下是此错误的检查点：

Following are the checkpoints for this error:

1. 您应该使用 Interop.excel.Dll 。 Excel.Exe 库会出现此错误。以 0x8 开头的错误是权限错误或指向内存的无效指针。
2. 转到 - >开始 - >跑 - >输入 REGSVR32 OLE32.DLL - > OK
   
   这将显示消息： ole32.dll成功

1. You should be using the Interop.excel.Dll. the Excel.Exe library will give this error. Errors starting with 0x8 are permission errors or invalid pointer to memory.
2. Go to --> Start --> run --> Enter REGSVR32 OLE32.DLL --> OK
   This will show the message : ole32.dll succeeded

感谢您的回复。我已成功注册ole32.dll但仍有问题。我确实认为存在无效的内存问题，但它可能与缺失有关，就像实例化我错过的东西一样。我们非常欢迎任何其他想法。

Hi Amit

Thanks for your response. I have registered ole32.dll successfully and still have the problem. I do think that there is an invalid memory problem but it could be to do with a missing like that instantiates something that I have missed. Any other ideas are really welcome.
