  • 发送邮件所用的核心知识点 
  •   微软封装好的MailMessage类:主要处理发送邮件的内容(如:收发人地址、标题、主体、图片等等)
  •   微软封装好的SmtpClient类:主要处理用smtp方式发送此邮件的配置信息(如:邮件服务器、发送端口号、验证方式等等)
  •   SmtpClient主要进行了三层的封装:Socket --> TcpClient --> SmtpClient
  • 具体代码请看如下所示:  
public class MyEmail
    {
        private MailMessage mMailMessage;   //主要处理发送邮件的内容(如:收发人地址、标题、主体、图片等等)
        private SmtpClient mSmtpClient; //主要处理用smtp方式发送此邮件的配置信息(如:邮件服务器、发送端口号、验证方式等等)
        private int mSenderPort;   //发送邮件所用的端口号(htmp协议默认为25)
        private string mSenderServerHost;    //发件箱的邮件服务器地址(IP形式或字符串形式均可)
        private string mSenderPassword;    //发件箱的密码
        private string mSenderUsername;   //发件箱的用户名(即@符号前面的字符串,例如:hello@163.com,用户名为:hello)
        private bool mEnableSsl;    //是否对邮件内容进行socket层加密传输
        private bool mEnablePwdAuthentication;  //是否对发件人邮箱进行密码验证

        ///<summary>
        /// 构造函数
        ///</summary>
        ///<param name="server">发件箱的邮件服务器地址</param>
        ///<param name="toMail">收件人地址(可以是多个收件人,程序中是以“;"进行区分的)</param>
        ///<param name="fromMail">发件人地址</param>
        ///<param name="subject">邮件标题</param>
        ///<param name="emailBody">邮件内容(可以以html格式进行设计)</param>
        ///<param name="username">发件箱的用户名(即@符号前面的字符串,例如:hello@163.com,用户名为:hello)</param>
        ///<param name="password">发件人邮箱密码</param>
        ///<param name="port">发送邮件所用的端口号(htmp协议默认为25)</param>
        ///<param name="sslEnable">true表示对邮件内容进行socket层加密传输,false表示不加密</param>
        ///<param name="pwdCheckEnable">true表示对发件人邮箱进行密码验证,false表示不对发件人邮箱进行密码验证</param>
        public MyEmail(string server, string toMail, string fromMail, string subject, string emailBody, string username, string password, string port, bool sslEnable, bool pwdCheckEnable)
