C#接收郵件

最近由於工作需要,接觸到了郵件服務器.以前我用CF寫過,感覺沒有什麼,我想用C#來實現會更簡單,但是萬萬沒想到C#沒有提供郵件接收的方法,令我很不解.通過我在網上查找,發現了一個國外公司寫好的接收郵件軟件,通過我把他的DLL破解之後就不用註冊了,要不可是需要花錢買序列號的啊好貴的啊!不過我希望各位如果有能力還是去買正版的爲好!我破解他的確是沒有辦法的辦法拉!請各位能夠理解^_^

下面是接收郵件的主程序代碼如下:

using System;
using System.Text;
using System.IO;
using Email.POP3;

namespace TestPOP3
...{
    class example
    ...{
        [STAThread]
        static void Main(string[] args)
        ...{
            //我測試的時候用的是163的郵箱，163的免費POP郵件服務器是pop.163.com。而163官方給出的是
            //pop.126.com在這裏不能用,原因是這個郵件服務器是有SSL加密的，GMAIL我也測試了也不能用都是這個原因
            POP3 objPOP3 = new POP3("pop.163.com", 110, "用戶名", "密碼");
            Console.WriteLine(objPOP3.Connect() ? "Connected" : "Can't connect");
            try
            ...{
                if (objPOP3.IsAPOPSupported)
                ...{
                    Console.WriteLine(objPOP3.SecureLogin() ? "Secure Logged in" : "Can't login");
                }
                else
                ...{
                    Console.WriteLine(objPOP3.Login() ? "Logged in" : "Can't login");
                }
                objPOP3.QueryServer();
                Console.WriteLine("Emails count: " + objPOP3.TotalMailCount);
                //以下的FOR循環是顯示出所有收件箱裏面的郵件信息
                for (int i = 1; i <= objPOP3.TotalMailCount; i++)
                ...{
                    EmailMessage objEmail = objPOP3.GetMessage(i, false); // use true to get headers only
                    Console.WriteLine("NEW MESSAGE:------------------");
                    Console.WriteLine("FROM: " + objEmail.From);
                    Console.WriteLine("TO: " + objEmail.To);
                    Console.WriteLine("CC: " + objEmail.Cc);
                    Console.WriteLine("SUBJECT: " + objEmail.Subject);
                    Console.WriteLine("DATE: " + objEmail.Date);
                    Console.WriteLine("CONTENT-TYPE: " + objEmail.ContentType);
                    Console.WriteLine("CHARSET: " + objEmail.Charset);
                    Console.WriteLine("MESSAGE-ID: " + objEmail.GetCustomHeader("Message-ID"));
                    Console.WriteLine("MESSAGE SIZE: " + objEmail.Size);
                    if (objEmail.IsAnyAttachments)

                        ...{
                            //調用郵件附件的方法
                            processAttachment((Attachment)objEmail.Attachments[a], 1);
                        }
                    }
                    else
                    ...{

                    }
