Outlook对话历史记录

Question

我正在研究创建一个Outlook插件，可以从对话历史记录文件夹中选择一个对话，然后单击将其保存到文件夹的按钮。有没有人有任何指示我如何选择对话历史记录文件夹和通过C＃运行搜索以及选择对话。

Answer 1

public static List<Outlook.MAPIFolder> GetFolders() 
    { 

     List<Outlook.MAPIFolder> _list = new List<Outlook.MAPIFolder>(); 

     Outlook.MAPIFolder root = OutlookApplication.Session.DefaultStore.GetRootFolder(); 


     foreach (Outlook.MAPIFolder folder in root.Folders) 
     { 
      _list.Add(folder); 
     } 

     return _list; 
    } 

    public static Outlook.MAPIFolder GetFolderByEntryId(string entryId) 
    { 
     List<Outlook.MAPIFolder> folders = GetFolders(); 
     return folders.Where(x => x.EntryID == entryId).FirstOrDefault(); 
    } 

    public static Outlook.MAPIFolder GetFolderByName(string folderName) 
    { 
     List<Outlook.MAPIFolder> folders = GetFolders(); 
     return folders.Where(x => x.Name == folderName).FirstOrDefault(); 
    } 

而且

public static List<Outlook.MailItem> GetSelectedItem() 
    { 
     List<Outlook.MailItem> _list = new List<Outlook.MailItem>(); 

     Outlook.Selection outlookSelection = OutlookApplication.ActiveExplorer().Selection; 

     for (int i = 1; i < outlookSelection.Count; i++) 
     { 
      Outlook.MailItem mailItem = (Outlook.MailItem)outlookSelection[i]; 

      _list.Add(mailItem); 
     } 

     return _list; 
    } 

    public static List<Outlook.MailItem> GetMailItems(string FolderName) 
    { 
     List<Outlook.MailItem> _list = new List<Outlook.MailItem>(); 

     Outlook.MAPIFolder theFolder = OutlookApplication.Session.GetFolderFromID(GetFolderByName(FolderName).EntryID); 

     foreach (Object item in theFolder.Items) 
     { 
      Outlook.MailItem mailItem = (Outlook.MailItem)item; 

      if (mailItem != null) 
      { 
       _list.Add(mailItem); 
      } 
     } 

     return _list; 

    }
