Question

我正在尝试阅读gmail帐户以获取从手机（我的手机）发送的gps数据（在电子邮件的文本中）

using (Pop3Client cl = new Pop3Client())
            {
                cl.UserName = "crash893";
                cl.Password = "password";
                cl.ServerName = "pop.gmail.com";
                cl.AuthenticateMode = Pop3AuthenticateMode.Pop;
                cl.Ssl = true;
                cl.Authenticate();
                ///Get first mail of my mailbox
                Pop3Message mg = cl.GetMessage(1);  <<<<<<<<<< ERROR
                String MyText = mg.BodyText;
                ///If the message have one attachment
                Pop3Content ct = mg.Contents[0];
                ///you can save it to local disk
                ct.DecodeData("c:\\test.txt");
            }

但我在“获取第一封邮箱邮件

”时遇到异常

"Higuchi.Net.Pop3.Pop3ConnectException: Pop3 connection is closed
at Higuchi.Net.Pop3.Pop3Client.SendCommand(String inCommand)
at Higuchi.Net.Pop3.Pop3Client.Execute(String inCommand, Boolean inIsMultiLine)
at Higuchi.Net.Pop3.Pop3Client.Execute(Pop3Command inCommand)
at Higuchi.Net.Pop3.Pop3Client.GetMessage(Int64 inMailIndex)"}

理想情况下，我想要打开这个读取此帐户中所有新未读电子邮件的特定主题行，然后读取正文中的数据并将其标记为已读

有谁知道它出错的原因

有没有人对c＃mail有任何经验，嘿可以指出我正确的方向阅读和制作电子邮件阅读等

Answer 1

无法使用POP协议将电子邮件标记为已读。

尝试使用IMAP。

cl.Port = 995;

        using (Pop3Client cl = new Pop3Client())
        {
            cl.UserName = "ewgsdssw";
            cl.Password = "sdgwsegw";
            cl.ServerName = "pop.gmail.com";
            cl.AuthenticateMode = Pop3AuthenticateMode.Pop;
            cl.Port = 995;
            cl.Ssl = true;
            cl.Authenticate();
            ///Get first mail of my mailbox
            ///
            int total = Convert.ToInt16(cl.GetTotalMessageCount());

            while (total >= 1)
            {
                Pop3Message mg = cl.GetMessage(total);
                if (mg.Subject == "I am Here")
                {

                    // http://maps.google.com/maps?q=38.89552,-77.43265
                    //(+/- 76 metres.)

                    string location = mg.BodyText;
                    location = location.Replace("http://maps.google.com/maps?q=","~");
                    location = location.Replace("metres.)\r\n\r\n","~");

                    location = location.Split('~')[1];

                    location = location.Replace("(+/- ", ",");
                    location = location.Replace("\r\n", "");


                    string[] data = location.Split(',');
                    string lat = data[0];
                    string lon = data[1];
                    string res = data[2];
                    DateTime time = mg.Date;

                    textBox1.AppendText(string.Format("Lat: {0} LON: {1} Res: {2} TIME: {3}\r\n",lat,lon,res,time.ToString()));

                }

                total--;
            }

        }

Answer 4

我没有使用C＃Mail的经验，这个答案可能无济于事，但我在尝试编写电子邮件发送/接收相关代码时经历过一些奇怪。

原来我们在工作中运行的防病毒软件有一个允许.EXE的白名单，可以进行/出站POP3或SMTP连接。这有什么可能是你的问题吗？
