c# - 使用 OpenPop.NET 删除邮箱中的消息

Question

我正在使用 OpenPop.NET 客户端通过 Pop3 协议(protocol)访问我的邮箱。一切都很好，除了一件事:我无法删除消息。连sample从官方网站没有帮助。我试过几个邮件服务器:gmail.com, yandex.ru, rambler.ru 情况都是一样的。

更新 - 添加代码。

static void Main(string[] args)
{
    DeleteMessageOnServer("pop.gmail.com", 995, true, USERNAME, PASSWORD, 1);
}

public static void
    DeleteMessageOnServer(string hostname, int port, bool useSsl, string username,
    string password, int messageNumber)
{
    // The client disconnects from the server when being disposed
    using (Pop3Client client = new Pop3Client())
    {
        // Connect to the server
        client.Connect(hostname, port, useSsl);

        // Authenticate ourselves towards the server
        client.Authenticate(username, password);

        // Mark the message as deleted
        // Notice that it is only MARKED as deleted
        // POP3 requires you to "commit" the changes
        // which is done by sending a QUIT command to the server
        // You can also reset all marked messages, by sending a RSET command.
        client.DeleteMessage(messageNumber);

        // When a QUIT command is sent to the server, the connection between them are closed.
        // When the client is disposed, the QUIT command will be sent to the server
        // just as if you had called the Disconnect method yourself.
    }
}

Answer 1

删除通过 .DeleteMessage(messageNumber); 方法标记的电子邮件发生在调用 .Disconnect(); 方法时。
