Question

我在下面的代码中完成了以下操作，但仍然获得了ServiceObjectPropertyException。我显然按照建议here too加载了该属性。请任何人帮忙指出我做错了什么

this.ExchangeService = new ExchangeService(ExchangeVersion.Exchange2013);

                this.ExchangeService.Credentials = new WebCredentials(mailBox, password);
                this.ExchangeService.Url = new Uri("https://mail.xxxxxxxxxxx.com/EWS/Exchange.asmx");                

                PropertySet itemProperty = new PropertySet();
                itemProperty.RequestedBodyType = BodyType.Text;


                SearchFilter searchFilter = new SearchFilter.SearchFilterCollection(LogicalOperator.And, new SearchFilter.IsEqualTo(EmailMessageSchema.IsRead, false));

                ItemView view = new ItemView(999);
                view.PropertySet = itemProperty;                

                List<ExchangeMailResponse> emails = new List<ExchangeMailResponse>();

                FindItemsResults<Item> emailMessage = this.ExchangeService.FindItems(WellKnownFolderName.Inbox, searchFilter, view);                               


                foreach (Item mail in emailMessage)
                {

                    ExchangeMailResponse email = new ExchangeMailResponse();


                    mail.Load(itemProperty);                  

                   email.Message = mail.Body.Text;                   


                }

使用您尝试使用的属性集，因为您还没有使用BasepropertySet重载，并且您还没有添加任何属性，您只能通知它以返回IdOnly。因此，在基本级别，您至少需要添加Body属性，例如

itemProperty.Add(ItemSchema.Body);

但是，您无法在FindItems操作中使用该属性集，因此我建议您更改类似

的代码

        SearchFilter searchFilter = new SearchFilter.SearchFilterCollection(LogicalOperator.And, new SearchFilter.IsEqualTo(EmailMessageSchema.IsRead, false));

        PropertySet FindItemPropertySet = new PropertySet(BasePropertySet.IdOnly);

        ItemView view = new ItemView(999);
        view.PropertySet = FindItemPropertySet;
        PropertySet GetItemsPropertySet = new PropertySet(BasePropertySet.FirstClassProperties);
        GetItemsPropertySet.RequestedBodyType = BodyType.Text;


        FindItemsResults<Item> emailMessages = null;
        do
        {
            emailMessages = service.FindItems(WellKnownFolderName.Inbox, searchFilter, view);
            if (emailMessages.Items.Count > 0)
            {
                service.LoadPropertiesForItems(emailMessages.Items, GetItemsPropertySet);
                foreach (Item Item in emailMessages.Items)
                {
                    Console.WriteLine(Item.Body.Text);
                }
            }
        } while (emailMessages.MoreAvailable);
