Question

当我在C＃中尝试追加命令时，请参阅代码：

private readonly string n = Environment.NewLine;
public string CreateDraft()
    {
        string output;
        string command = "MIME-Version: 1.0" + n +
                         "From: username@gmail.com" + n +
                         "To: username@gmail.com" + n +
                         "Subject: " + machineId + n +
                         "Content-Type: text/plain; charset=utf-8" + n +
                         "TESTING" + n;
        output =  ReceiveResponse("$$ APPEND [Gmail]/Drafts (\\Draft) {" +      Encoding.UTF8.GetByteCount(command) + "}" + n);

        output += n + ReceiveResponse(command);

        return output;
    }

private string ReceiveResponse(string command)
    {
        try
        {
            if (InternetIsConnected() == true)
            {
                if (!(tcpc.Connected))
                {
                    Connect();
                }

                if (tcpc.Connected)
                {
                    dummy = Encoding.ASCII.GetBytes(command);
                    ssl.Write(dummy, 0, dummy.Length);
                    ssl.Flush();

                    response = "";

                    do
                    {
                        bytes = ssl.Read(buffer, 0, buffer.Length);
                        Decoder decoder = Encoding.UTF8.GetDecoder();
                        char[] chars = new char[decoder.GetCharCount(buffer, 0, bytes)];
                        decoder.GetChars(buffer, 0, bytes, chars, 0);

                        response += new string(chars);
                    } while (response.Contains("$$") == false && (response.Contains("+") == false));

                    return response;
                }

                return "Failure: Terminal Disconnected";
            }
        }
        catch (Exception ex)
        {
        }

        return "Failure";
    }

它说，BAD无法解析命令。它在Encoding.UTF8.GetByteCount(command)上崩溃，它的长度为162，但是当我尝试160时，它会起作用。 GMAIL只是不同意我的意思，然后停止工作。

Answer 1

你的命令实际上是错的;你必须发送文字，然后发送CRLF，然后等待服务器告诉你发送更多，然后发送正文。

FooLib.LinkWith.cs之类的内容有误，应为{3}foo，等待服务器告诉您继续{3}\r\n。

GMail IMAP追加{长度}
