发送邮件类

    　　先引用命名空间：using System.Net.Mail; 
　　　　下面这这个邮件类直接用到项目中OK！！！
       /// <summary>
        /// 发送邮件
        /// </summary>
        /// <param name="to">接收方邮件地址</param>
        /// <param name="title">邮件标题</param>
        /// <param name="content">邮件正文内容</param>
        /// <returns></returns>
        /// <author>jeffrey zhang</author>
        /// <date>2012-4-16</date>
        static bool sendMail(string to, string title, string content)
        {
            string strHost = "xxx.163.com";   //STMP服务器地址
            string strAccount = "xxx";       //SMTP服务帐号
            string strPwd = "xxxx";       //SMTP服务密码
