c# - OpenPop.Net 没有收到来自 Gmail 的所有电子邮件

Question

我有这个代码:

public List<Attachment> GetAttachments() {
    string hostname = "pop.gmail.com";
    int port = 995;
    bool useSSL = true;
    string attachmentType = "application/pdf";

    string email = "myemail@gmail.com";
    string emailFrom = "someone@gmail.com";
    string password = TxtBoxPassword.Text;

    if (!string.IsNullOrWhiteSpace(password))
    {
        Pop3Client client = new Pop3Client();
        client.Connect(hostname, port, useSSL);
        client.Authenticate(email, password, AuthenticationMethod.UsernameAndPassword);

        List<Attachment> listAttachments = new List<Attachment>();

        int count = client.GetMessageCount();
        for (int i = count; i >= 1; i--)
        {
            Message message = client.GetMessage(i);
            if (message.Headers.From.MailAddress.Address == emailFrom)
            {
                List<MessagePart> attachments = message.FindAllAttachments();
                foreach (MessagePart attachment in attachments)
                {
                    if (attachment.ContentType.MediaType == attachmentType)
                        listAttachments.Add(new Attachment(attachment));
                }
            }
        }
    }
}

阅读电子邮件帐户中的所有电子邮件。

它访问电子邮件帐户并从已发送/收件箱文件夹中获取 265 封电子邮件。

目前我的帐户中有超过一千封电子邮件，所以我希望在电子邮件数量上看到这个数字。

阻止我接收所有电子邮件的代码/Gmail 帐户设置中缺少什么？

谢谢

嗯，Gmail 在涉及其 POP3 功能时有一些怪癖。在 What non-standard behaviour features does Gmail exhibit, when it is programmatically used as a POP3 server? 上查看我的回答.我不认为您可以更改任何设置来解决您的问题。
