Trello Manatee添加附件

Question

我试图添加一个附件到一个预先创建的Trello卡使用Manatee。

这就是我制作卡片的方式，我对它没有问题：

        /// <summary>
        ///  This function creates a card on Trello <Board_Name> board, into the list named <List_Name>.
        ///  It creates a card with the title and descrition comming from the function which is called
        /// </summary>
        /// <param name="subject"> This is the subject (Title) of the ticket </param>
        /// <param name="body"> This is the body section (description) of the ticket </param>
        public string createTrelloTicketCard(string subject, string body)
        {
            string cardId = null;
            trelloToken = adminTrelloToken; // define who is creating the card

            Run(() =>
            {
                TrelloProcessor.WaitForPendingRequests = true;
                var board = new Board(<Board_ID>); // board id
                var list = board.Lists[5]; // The sixth list of the board 

                var card = list.Cards.Add(subject); // create a card with the subject from tblTasks
                cardId = card.Id; // get the created card ID
                card.Description = body; // define description from tblTasks
                
                // Add all the IT members to the card
                for (int i = 0; i < numberOfItMembersInBoard; i ++)
                {
                    card.Members.Add(board.Members[i]); 
                }
            });

            return cardId;
        }

这就是我如何尝试添加附件到卡。此函数中出现了以下问题：

public void InsertAttachementIntoTrelloCard(string cardId, byte[] buffer, string name)
        {
            Run(() =>
            {
                TrelloProcessor.WaitForPendingRequests = true;

                var board = new Board(<Board_ID>); // board id
                
                var list = board.Lists[5]; // The sixth list of the board 
                
                var card = new Card(cardId); // specify the card that the file is going to be attached
                card.Description = "Test3";

                card.Attachments.Add(buffer, name); // Here I get the error
            });
        }

当我试图附加文件时，我得到一个错误，从下面这个句子开始：

对象引用未设置为对象的实例.

我非常肯定创建的字节数组是正确的，当我删除该行时，程序结束时没有任何错误。我用错方法了吗？

这里是堆栈跟踪：

ex.Message =“对象引用未设置为对象的实例”。 (应Manatee.Trello.Internal.DataAccess.JsonRepository.PrepRequest(IRestRequest请求，e:\Projects\Manatee.Trello\Manatee.Trello\Internal\DataAccess\JsonRepository.cs:line 79中的ex.StackTrace =“ex.StackTrace=”，在端点端点，在e:\Projects\Manatee.Trello\Manatee.Trello\Internal\DataAccess\JsonRepository.cs:line 74中，在Manatee.Trello.Internal.DataAccess.JsonRepository.ExecuteT中，在e:\Projects\Manatee.Trello\Manatee.Trello\Internal\DataAccess\JsonRepository.cs:line中，46在Manatee.Trello.AttachmentCollection.Add(Byte[]数据，(字符串名称)在e:\Projects\Manatee.Trello\Manatee.Trello\AttachmentCollection.cs:line 112 at Live.XmlFax.XmlFaxForm.<>c__DisplayClass8.b__7() in c:\Users\arif.gencosmanoglu\Documents\EnteringC#\Printer Project\XmlFax\XmlFaxForm.cs:line 2035 at Live.XmlFax.XmlFaxForm.Run( action ) in c:\Users\arif.gencosmanoglu\Documents\EnteringC#\Printer Project\XmlFax\XmlFaxForm.cs:line 1724 at Live.XmlFax.XmlFaxForm.InsertAttachementIntoTrelloCard(String cardId，Byte[] buffer，( c:\Users\arif.gencosmanoglu\Documents\EnteringC#\Printer Project\XmlFax\XmlFaxForm.cs:line 2023 at Live.XmlFax.XmlFaxForm.ReadTicketEmail() at Live.XmlFax.XmlFaxForm.ReadTicketEmail() in c:\Users\arif.gencosmanoglu\Documents\EnteringC#\Printer Project\XmlFax\XmlFaxForm.cs:line 1981 at Live.XmlFax.XmlFaxForm.cmdItTicket_Click(Object Project\XmlFax\XmlFaxForm.cs:line，EventArgs e) ( c:\Users\arif.gencosmanoglu\Documents\EnteringC#\Printer Project\XmlFax\XmlFaxForm.cs:line 1884 )

Answer 1

我不知道问题出在哪里。到堆栈跟踪中该点的每一条路径都包含所有的依赖项，不应该发生该错误。

请确保您有以下最新的Nuget软件包：

• Manatee.Trello
• Manatee.Trello.ManateeJson
• Manatee.Trello.RestSharp
