Question

我正在尝试使用Manatee API为预先创建的Trello卡添加附件。

这就是我创建卡片的方式，我没有遇到任何问题：

        /// <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;
        }

这是我尝试在卡上添加附件的方法。此功能发生此问题：

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
            });
        }

当我尝试附加文件时，我从这句话开始出错：

未将对象引用设置为对象的实例。

我很确定创建的字节数组是正确的，当我删除该行时程序结束没有任何错误。我使用了错误的方法吗？

这是堆栈跟踪：

ex.Message =＆＃34;对象引用未设置为对象的实例。＆＃34;

ex.StackTrace =＆＃34;在   Manatee.Trello.Internal.DataAccess.JsonRepository.PrepRequest（IRestRequest   请求，TrelloAuthorization auth）in   E：\项目\ Manatee.Trello \ Manatee.Trello \内部\的DataAccess \ JsonRepository.cs：行   79点   Manatee.Trello.Internal.DataAccess.JsonRepository.BuildRequest（TrelloAuthorization   auth，Endpoint endpoint，IDictionary`2 parameters）in   E：\项目\ Manatee.Trello \ Manatee.Trello \内部\的DataAccess \ JsonRepository.cs：行   74点   Manatee.Trello.Internal.DataAccess.JsonRepository.Execute [T]（TrelloAuthorization   auth，Endpoint endpoint，IDictionary＆＃39; 2参数）in   E：\项目\ Manatee.Trello \ Manatee.Trello \内部\的DataAccess \ JsonRepository.cs：行   46 at Manatee.Trello.AttachmentCollection.Add（Byte [] data，String   姓名）in   E：\项目\ Manatee.Trello \ Manatee.Trello \ AttachmentCollection.cs：行   112点   Live.XmlFax.XmlFaxForm＆LT;＆GT; c__DisplayClass8.b__7（）   在c：\ Users \ arif.gencosmanoglu \ Documents \ EnteringC＃\ Printer中   Project \ XmlFax \ XmlFaxForm.cs：第2035行   Live.XmlFax.XmlFaxForm.Run（Action action）in   C：\用户\ arif.gencosmanoglu \文档\ EnteringC＃\打印机   Project \ XmlFax \ XmlFaxForm.cs：第1724行   Live.XmlFax.XmlFaxForm.InsertAttachementIntoTrelloCard（String cardId，   字节[]缓冲区，字符串名称）中   C：\用户\ arif.gencosmanoglu \文档\ EnteringC＃\打印机   Project \ XmlFax \ XmlFaxForm.cs：第2023行   Live.XmlFax.XmlFaxForm.ReadTicketEmail（）in   C：\用户\ arif.gencosmanoglu \文档\ EnteringC＃\打印机   Project \ XmlFax \ XmlFaxForm.cs：1981年的第一行   Live.XmlFax.XmlFaxForm.cmdItTicket_Click（Object sender，EventArgs e）   在c：\ Users \ arif.gencosmanoglu \ Documents \ EnteringC＃\ Printer中   Project \ XmlFax \ XmlFaxForm.cs：第1884行

Answer 1

我不知道问题出在哪里。堆栈跟踪中到达该点的每条路径都包含所有依赖关系，并且该错误不应该发生。

请确保您拥有以下最新的Nuget套餐：

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