Question

我有一个c＃类，用于读取Lotus电子邮件中的任何附件并将其保存到本地驱动器。当我将“”作为第一个参数传递给GetDataBase方法并将本地系统的.nsf文件的完整路径作为第二个参数传递时，它工作正常。但是，如果我删除“”并且我将本地系统全名指定为第一个参数，则返回空值。

任何权限都有问题吗？如果是这样，即使我将“”作为第一个参数传递，它也不应该工作。否则，我应该在系统/服务器级别拥有任何其他权限吗？请帮我解决这个问题。

最后，我可以通过以下方式完成。而且我想把它发布给一些人至少不会再受苦了。

以下代码是从lotus电子邮件中读取附件并将其保存到物理位置。

string lotusServerName = ConfigurationSettings.AppSettings [“Lotus_Server”]。ToString（）; string lotusDBFilePath = ConfigurationSettings.AppSettings [“Lotus_DB_File_Path”]。ToString（）; string password = ConfigurationSettings.AppSettings [“Password”]。ToString（）; string sourceFolder = ConfigurationSettings.AppSettings [“Source_Folder”]。ToString（）; string targetFolder = ConfigurationSettings.AppSettings [“Target_Folder”]。ToString（）; string documentsFolder = ConfigurationSettings.AppSettings [“Documents_Folder”]。ToString（）;

        //Creating the notes session and passing password
        NotesSession session = new NotesSession();
        session.Initialize(password);

        //Getting the DB instance by passing the servername and path of the mail file.  
        //third param "false" will try to check the DB availability by opening the connection
        //if it cannot open, then it returns null.
        NotesDatabase NotesDb = session.GetDatabase(lotusServerName, lotusDBFilePath, false);

        //Get the view of the source folder
        NotesView inbox = NotesDb.GetView(sourceFolder);

        //looping through each email/document and looking for the attachments
        //if any attachments found, saving them to the given specified location
        //moving the read mails to the target folder
        NotesDocument docInbox = null;
        int docCnt = inbox.EntryCount;
        for (int currDoc = 0; currDoc < docCnt; currDoc++) {
            docInbox = inbox.GetFirstDocument();
            object[] items = (object[])docInbox.Items;
            foreach (NotesItem nItem in items) {
                if (nItem.Name == "$FILE") {
                    NotesItem file = docInbox.GetFirstItem("$File");
                    string fileName = ((object[])nItem.Values)[0].ToString();
                    NotesEmbeddedObject attachfile = (NotesEmbeddedObject)docInbox.GetAttachment(fileName);

                    if (attachfile != null) {
                        attachfile.ExtractFile(documentsFolder + fileName);
                    }
                }
            }
            docInbox.PutInFolder(targetFolder, true);//"true" creates the folder if it doesn't exists
            docInbox.RemoveFromFolder(sourceFolder);
        }

        //releasing resources
        if (session != null)
            session = null;
        if (NotesDb != null)
            NotesDb = null;
        if (inbox != null)
            inbox = null;
        if (docInbox != null)
            docInbox = null;

以下是从.config文件中读取的值。

如果您在系统中拥有Lotus邮件客户端并且您可以从邮件服务器访问邮件，则上述代码将正常工作。您不需要任何其他优惠。

NotesSession.GetDataBase方法返回null值
