OpenPop Pop3 winform MaxMessage c#

Question

我对邮件程序中的信息有问题。如果我有20封邮件，它可以加载的很快，但如果我有700，这是一个问题，它需要很长的时间。我可以去做咖啡然后回来。如何将最大信息设置为50。

        try
        {

            client.Connect(comboBox5.Text, 995, true);
            client.Authenticate(textBox6.Text, textBox5.Text, OpenPop.Pop3.AuthenticationMethod.UsernameAndPassword);

      int count = client.GetMessageCount();
            string htmlContained = "";


            for (int i = count; i >= 1; i -= 1)
            {

                OpenPop.Mime.Message message = client.GetMessage(i);

                OpenPop.Mime.MessagePart html = message.FindFirstHtmlVersion();


                if (html != null)
                {

                    htmlContained = html.GetBodyAsText();


                } else
                {
                    html = message.FindFirstPlainTextVersion();
                    if (html != null)
                    {
                        htmlContained = html.GetBodyAsText();
                    }
                }
                string name = message.Headers.Subject;
                if (name == "")
                {
                    name = "Usigned";
                }

                dt.Rows.Add(new object[] { name.ToString(), message.Headers.From.DisplayName, message.Headers.From.Address, htmlContained, message.Headers.DateSent });

            }

                client.Disconnect();

        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message);
        }

}

Answer 1

for (int i = count; i >= 1; i -= 1) 

->

for (int i = 0; i < count && i < 50; i++)

或者(据我说不那么红)：

for (int i = count; i >= 1; && (count - i) < 50; i -= 1) 

您还可能希望实现分页：

var pageSize = 50;
var startPage = x;

for (int i = x * pageSize; i < count && i < pageSize; i++)
