我可以使用SmtpClient訪問已發送的Email文件夾並刪除已發送的email嗎？

Question

我正在使用SmtpClient發送帶附件的 email。

我可以使用SmtpClient從已發送的文件夾中刪除已發送的 email 嗎？

這是我的代碼：

ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls12;

using var mailMessage = new MailMessage();

mailMessage.To.Add(new MailAddress(s));
mailMessage.From = new MailAddress("mohammad.jouhari@gmail.com");
mailMessage.Subject = "Remote Freelance Web Developer,Mohammad Jouhari Latest CV";
mailMessage.Body = "Dear Hiring Manager,\r\n\r\n Please find attached CV.\r\n\r\n " +
                        "My work sample:https://github.com/mohammadjouhari.\r\n\r\n" +
                        "My linkedin Profile: https://www.linkedin.com/in/mohammad-jouhari-42461330/";

string pdfFilePath = "C:\\Users\\m_243\\OneDrive\\Desktop\\microsoft documentation\\.net core\\SendEmailTest" +
                        "\\SendEmailTest\\wwwroot\\MohammadJouhariCV.pdf";
byte[] bytes = System.IO.File.ReadAllBytes(pdfFilePath);

var attachment = new Attachment(new MemoryStream(bytes), "MohammadJouhariCV.PDF");
mailMessage.Attachments.Add(attachment);

NetworkCredential loginInfo = new NetworkCredential("mohammad.jouhari@gmail.com", ""); // password for connection smtp if you don't have have then pass blank

SmtpClient _smtpClient = new SmtpClient();
_smtpClient.Host = "smtp.gmail.com";
_smtpClient.Port = 587;
_smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
_smtpClient.EnableSsl = true;
_smtpClient.UseDefaultCredentials = false;
_smtpClient.Credentials = loginInfo;
_smtpClient.Send(mailMessage); // _smtpClient will be disposed by container
_smtpClient.Dispose();

我正在嘗試這段代碼

Pop3Client pop3 = new Pop3Client();
pop3.Host = "smtp.gmail.com";
pop3.Username = "mohammad.jouhari@gmail.com";
pop3.Password = "";
pop3.Port = 587;
pop3.EnableSsl = true;

pop3.Connect();
pop3.DeleteAllMessages();
pop3.Dispose();

我在pop3.Connect();

否DELE命令從收件箱中刪除，而不是從發件箱中刪除。 從其他郵箱中刪除電子郵件是通過特定於平台的 api 完成的 - 在 Gmail 中執行此操作的方式將不同於 Outlook。例如，Microsoft 使用其 Graph api 來管理郵箱。 Google 稱它們為“標簽”而不是“郵箱”，一個 email 可以關聯多個 label
