here is my sample code ,

using Microsoft.Office.Interop.Outlook;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace MailApplication
{
    class Program
    {
        static void Main(string[] args)
        {
       //     Microsoft.Office.Interop.Outlook.MAPIFolder inbox =
       //    Application.ActiveExplorer().Session.GetDefaultFolder
       //(Microsoft.Office.Interop.Outlook.OlDefaultFolders.olFolderInbox);

       //     Microsoft.Office.Interop.Outlook.Items unreadItems = inbox.
       //         Items.Restrict("[Unread]=true");

       //     MessageBox.Show(
       //         string.Format("Unread items in Inbox = {0}", unreadItems.Count));


            SmtPop.POP3Client pop = new SmtPop.POP3Client();

            pop.Open("pop.gmail.com",995, "abc@gmail.com", "abdre@345");
            
           
            // Get message list from POP server
            
            SmtPop.POPMessageId[] messages = pop.GetMailList();
            
            if (messages != null)
            {

                // Walk attachment list
                foreach (SmtPop.POPMessageId id in messages)
                {
                    SmtPop.POPReader reader = pop.GetMailReader(id);
                    SmtPop.MimeMessage msg = new SmtPop.MimeMessage();

                    // Read message
                    msg.Read(reader);
                    if (msg.AddressFrom != null)
                    {
                        String from = msg.AddressFrom[0].Name;
                        Console.WriteLine("from: " + from);
                    }
                    if (msg.Subject != null)
                    {
                        String subject = msg.Subject;
                        Console.WriteLine("subject: " + subject);
                    }
                    if (msg.Body != null)
                    {
                        String body = msg.Body;
                        Console.WriteLine("body: " + body);
                    }
                    //string attach1 = Convert.ToString(msg.Attachments);
                    //Console.WriteLine(attach1);
                    if (msg.Attachments != null )
                    {
                        // Do something with first attachment
                        SmtPop.MimeAttachment attach = msg.Attachments[0];
                       
                        if (attach.Filename == "")
                        {
                            // Read data from attachment
                            Byte[] b = Convert.FromBase64String(attach.Body);
                            System.IO.MemoryStream mem = new System.IO.MemoryStream(b, false);

                            //BinaryFormatter f = new BinaryFormatter();
                            // DataClass data= (DataClass)f.Deserialize(mem); 
                            mem.Close();
                        }

                        // Delete message
                        // pop.Dele(id.Id);
                    }
                }
            }
            pop.Quit();
        }
    }
}
