我正在尝试获取未读电子邮件,然后将其标记为已读。

运行代码时出现此异常:

  

ServiceObjectPropertyException是unhandeld:

     

未处理的类型异常   ' Microsoft.Exchange.WebServices.Data.ServiceObjectPropertyException'   发生在Microsoft.Exchange.WebServices.dll

尝试将Exchange邮件对象映射到业务模型对象时发生此错误。

这是Map方法:

class MailMapper
{
     public static PhishingMail Map(EmailMessage OutlookMail)
     {
          //Map Exchange email object op Business model email object
          PhishingMail readMail = new PhishingMail();
          readMail.Subject = OutlookMail.Subject;
          return readMail;
      }
}

这是将电子邮件标记为已读的代码。

public List<PhishingMail> GetEmails() 
{
    phishingMailList = new List<PhishingMail>();

    FolderId InboxId = new FolderId(WellKnownFolderName.Inbox, "A*******m@i*****nl");

    FindItemsResults<Item> findResults = service.FindItems(InboxId, new ItemView(100));

    foreach (Item phishingmail in findResults.Items)
    {
        ((EmailMessage)phishingmail).Load(new PropertySet(BasePropertySet.IdOnly, EmailMessageSchema.IsRead)); 

        if (!((EmailMessage)phishingmail).IsRead) 
        {
            ((EmailMessage)phishingmail).IsRead = true;
            ((EmailMessage)phishingmail)
                .Update(ConflictResolutionMode.AutoResolve);
        }

        PhishingMail mail = MailMapper.Map((EmailMessage)phishingmail);

        phishingMailList.Add(new PhishingMail());

        ///   Console.WriteLine(mail.Subject);
    }
    return phishingMailList;
}

我做错了什么? map方法有什么问题?

加载项目时,需要加载要加载的属性。

item.Load(new PropertySet(PropertySet.FirstClassProperties)); 

如果加载后需要更多属性,可以执行以下操作:

Service.LoadPropertiesForItems(items, PropertySet.FirstClassProperties);
