GetTotalMessageCount Exception

Jun 9, 2010 at 8:37 AM


I get "Input string not in correct format" by calling GetTotalMessageCount in Pop3Client class.

Do I miss something? Is there an code sample for setting up the pop3 client ?


Thanks in advance

My initial code was:




Higuchi.Net.Pop3.Pop3Client popClient = new Higuchi.Net.Pop3.Pop3Client();
popClient.AuthenticateMode = Higuchi.Net.Pop3.Pop3AuthenticateMode.Pop;


popClient.Password ="xxxxxxx";
popClient.Port = 995;
popClient.ServerName ="";
popClient.Ssl = true;
popClient.UserName = "";
bool authpop = popClient.Authenticate();


if (authpop)




 long mc = popClient.GetTotalMessageCount();


 if (mc > 0)

long i = 1;
  while (i <= mc)
   Higuchi.Net.Pop3.Pop3Message msg = popClient.GetMessage(i);








As soon as I removed the line: 

popClient.Open() it worked....

Any ideas??


Thanks in advance

Open method will open connection to pop3 server.
Inside Authenticate method,the connection already opened.
So,you need not call open method after calling Authenticate method.
