Using this class in your C# application you can manage your mailbox and download and parse your messages.


This article explains a simple way to add mail support in your application. Just use the classes:

POP3class methods:

  • string DoConnect(String pop3host,int port, String user, String 
  • string GetStat()
  • string GetList()
  • string GetList(int num)
  • string Retr(int num)
  • string Dele(int num)
  • string Rset()
  • string Quit()
  • string GetTop(int num)
  • string GetTop(int num_mess, int num_lines)
  • string GetUidl()
  • string GetUidl(int num)
  • string GetNoop()

MessageClass methods:

  • string GetFrom(string messTop)
  • string GetDate(string messTop)
  • string GetMessID(string messTop)
  • string GetTo(string messTop)
  • string GetSubject(string messTop)
  • string GetBody(string AllMessage)

Using the code

The following sample illustrates how to use the classes:

POP3class pop3;
pop3 = new POP3class();
// and if we have mail:
MessageClass msg;
msg = new MessageClass();
string sMessageTop = msg.GetTop(1);
//OK, message is well, lets download it.
string sAllMessage = msg.Retr(1);

That's all.
