使用OpenPop.NET删除邮箱中的信息。

Question

我正在使用OpenPop.NET客户端通过Pop3协议访问我的邮箱。一切正常，除了一件事：我不能删除邮件。甚至 样品 我已经尝试了几个邮件服务器：gmail.com，yandex.ru，rambler.ru情况是一样的。

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

删除那些被标记的邮件。.DeleteMessage(messageNumber); 方法时，会发生 .Disconnect(); 方法被调用。

Answer 2

如上所述，当连接关闭时，邮件就会被删除，另外，邮件编号应该以1开头，而不是以0开头。以gmail为例，你需要进入 "设置->转发POPIMAP->当邮件用POP访问时"，选择 "删除gmail的副本"。
