public class Pop3MailService    {        public delegate void ReceivedMail();        public event ReceivedMail OnReceivedMail;        string userName = string.Empty;         string password = string

public class JMailService    {        public delegate void ReceivedMail();        public event ReceivedMail OnReceivedMail;        string userName = string.Empty;        string password = string.Emp

public class FaxFTPService    {        string _ftpServerIP = string.Empty;        string _ftpUserID = string.Empty;        string _ftpPassword = string.Empty;        //发送传真目录        string _ftpServe

在HtML代码中加入                               

序列化                    Bitmap bitMap = new Bitmap(filename);                    MemoryStream ms = new MemoryStream();                    bitMap.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
