和https://imapx.codeplex.com/

    List<Task> m = new List<Task>();
    private async void cmdLogin_Click(object sender, EventArgs e)
    {
        bool result = imapMail.Connection();
        if (result)
        {
            result = imapMail.LogIn(email, password);
            if (result)
            {
                var messes = imapMail.Folders[inbox].Messages;
                foreach (var x in messes)
                {
                    string from = "";
                    foreach (var addresses in x.From)
                    {
                        from = addresses.DisplayName;
                    }
                    listBox1.Items.Add(from + ": " + x.Subject);
                }
                foreach (ImapX.Message msgs in imapMail.Folders[inbox].Messages)
                {
                    m.Add(new Task(new Action(() => msgs.Process())));
                }
                await Task.WhenAll(m);

            }
            else { this.Text = "failed login"; }
        }
        else { this.Text = "Failed connection"; }
    }
}

这不会返回除冒号之外的任何内容，它应该返回一个显示名称：消息主题

在检索邮件详细信息（例如“from”，“subject”等）之前，首先需要在邮件上调用Process（）。如果查看source code for ImapX，您会看到Process（）涉及对IMAP服务器的服务器调用，以下载消息数据。

看起来你正在尝试在调用Process（）之前检索From地址，这将返回一个空字符串。您需要更改订单 - 首先调用Process（），然后才能检查消息详细信息。

请参阅下面的代码。我还没有测试过这个。

List<Task> m = new List<Task>();
private async void cmdLogin_Click(object sender, EventArgs e)
{
    bool result = imapMail.Connection();
    if (result)
    {
        result = imapMail.LogIn(email, password);
        if (result)
        {
            foreach (ImapX.Message msgs in imapMail.Folders[inbox].Messages)
            {
                m.Add(new Task(new Action(() => msgs.Process())));
            }
            await Task.WhenAll(m);

            var messes = imapMail.Folders[inbox].Messages;
            foreach (var x in messes)
            {
                string from = "";
                foreach (var addresses in x.From)
                {
                    from = addresses.DisplayName;
                }
                listBox1.Items.Add(from + ": " + x.Subject);
            }
        }
        else { this.Text = "failed login"; }
    }
    else { this.Text = "Failed connection"; }
}

ImapX没有给我电子邮件主题/消息信息：
