outlook - 计算 Outlook 文件夹中的电子邮件数量

Question

我想计算我收到的主题行中包含“xyz”字样的邮件数量。但我不希望它计算重复，我的意思是如果我收到一封主题为“xyz”的邮件并且我回复它，包括我自己我希望将其计为 1 而不是 2。在 Outlook 中可能吗？

是的，这绝对是可能的，您没有指定要使用的技术，但使用互操作的示例代码可能是：

var outlookApp = new Outlook.Application();
var mapi = outlookApp.GetNamespace("MAPI")
var root = mapi.GetDefaultFolder(OlDefaultfolders.olFolderInbox)

var folders = root.Folders;
int count = 0;
for(int i = folders.Count; i >= 1; i--)
{

  var folder = folders[i];
  count += GetCount(folder, 0);

  Marshal.ReleaseComObject(folder);

}
Marshal.ReleaseComObject(folders);

//... function
private int GetCount(MAPIFolder folder, int count)
{

  var folderItems = folder.Items;
  if(folderItems != null && folderItems.Count >= 1)
     {
         for(int i = folderItems.Count; i >= 1; i--)
         {
          //Check item.Subject for string logic
           count++;
          //Add item in collection variable to check duplicates, 
          //generate an id with subject + creationtime for tracking?
         }
     }
  if(folder.Folders != null && folder.Folders >= 1)
    {
        var subFolders = folder.Folders;
        for(int i = subfolders.Count; i >= 1; i--)
          {
             var subFolder = subFolders[i]
             count += GetCount(subFolder, count);
             Marshal.ReleaseComObject(subfolder);
          }
    }
   Marshal.ReleaseComObject(folderItems);
   return count;
 }

希望它可以帮助某人，
