C#實現郵件發送功能

• 發送郵件所用的核心知識點 

•   微軟封裝好的MailMessage類：主要處理髮送郵件的內容（如：收發人地址、標題、主體、圖片等等）
•   微軟封裝好的SmtpClient類：主要處理用smtp方式發送此郵件的配置資訊（如：郵件伺服器、傳送埠號、驗證方式等等）
•   SmtpClient主要進行了三層的封裝：Socket --> TcpClient --> SmtpClient

• 具體代碼請看如下所示：　　

public class MyEmail    {        private MailMessage mMailMessage;   //主要處理髮送郵件的內容（如：收發人地址、標題、主體、圖片等等）        private SmtpClient mSmtpClient; //主要處理用smtp方式發送此郵件的配置資訊（如：郵件伺服器、傳送埠號、驗證方式等等）        private int mSenderPort;   //發送郵件所用的連接埠號碼（htmp協議預設為25）        private string mSenderServerHost;    //寄件匣的郵件伺服器地址（IP形式或字串形式均可）        private string mSenderPassword;    //寄件匣的密碼        private string mSenderUsername;   //寄件匣的使用者名稱（即@符號前面的字串，例如：[email protected]，使用者名稱為：hello）        private bool mEnableSsl;    //是否對郵件內容進行socket層加密傳輸        private bool mEnablePwdAuthentication;  //是否對寄件者郵箱進行密碼驗證        ///<summary>        /// 建構函式        ///</summary>        ///<param name="server">寄件匣的郵件伺服器地址</param>        ///<param name="toMail">收件者地址（可以是多個收件者，程式中是以“;"進行區分的）</param>        ///<param name="fromMail">寄件者地址</param>        ///<param name="subject">郵件標題</param>        ///<param name="emailBody">郵件內容（可以以html格式進行設計）</param>        ///<param name="username">寄件匣的使用者名稱（即@符號前面的字串，例如：[email protected]，使用者名稱為：hello）</param>        ///<param name="password">寄件者郵箱密碼</param>        ///<param name="port">發送郵件所用的連接埠號碼（htmp協議預設為25）</param>        ///<param name="sslEnable">true表示對郵件內容進行socket層加密傳輸，false表示不加密</param>        ///<param name="pwdCheckEnable">true表示對寄件者郵箱進行密碼驗證，false表示不對寄件者郵箱進行密碼驗證</param>        public MyEmail(string server, string toMail, string fromMail, string subject, string emailBody, string username, string password, string port, bool sslEnable, bool pwdCheckEnable)        {            try            {                mMailMessage = new MailMessage();                mMailMessage.To.Add(toMail);                mMailMessage.From = new MailAddress(fromMail);                mMailMessage.Subject = subject;                mMailMessage.Body = emailBody;                mMailMessage.IsBodyHtml = true;                mMailMessage.BodyEncoding = System.Text.Encoding.UTF8;                mMailMessage.Priority = MailPriority.Normal;                this.mSenderServerHost = server;                this.mSenderUsername = username;                this.mSenderPassword = password;                this.mSenderPort = Convert.ToInt32(port);                this.mEnableSsl = sslEnable;                this.mEnablePwdAuthentication = pwdCheckEnable;            }            catch (Exception ex)            {                Console.WriteLine(ex.ToString());            }        }        public void Send()        {            try            {                if (mMailMessage != null)                {                    mSmtpClient = new SmtpClient();                    //mSmtpClient.Host = "smtp." + mMailMessage.From.Host;                    mSmtpClient.Host = this.mSenderServerHost;                    mSmtpClient.Port = this.mSenderPort;                    mSmtpClient.UseDefaultCredentials = false;                    mSmtpClient.EnableSsl = this.mEnableSsl;                    if (this.mEnablePwdAuthentication)                    {                        System.Net.NetworkCredential nc = new System.Net.NetworkCredential(this.mSenderUsername, this.mSenderPassword);                        //mSmtpClient.Credentials = new System.Net.NetworkCredential(this.mSenderUsername, this.mSenderPassword);                        //NTLM: Secure Password Authentication in Microsoft Outlook Express                        mSmtpClient.Credentials = nc.GetCredential(mSmtpClient.Host, mSmtpClient.Port, "NTLM");                    }                    else                    {                        mSmtpClient.Credentials = new System.Net.NetworkCredential(this.mSenderUsername, this.mSenderPassword);                    }                    mSmtpClient.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;                    mSmtpClient.Send(mMailMessage);                }            }            catch (Exception ex)            {                //m_CreateErrorLogTxt("程式池(Email)通知", "郵件發送失敗", ex.Message);            }        }    }
