本文实例讲述了C#使用自带的email组件发送邮件的方法。分享给大家供大家参考。具体实现方法如下：

#region 邮件发送
/// <summary>
/// 发送邮件支持HTML格式 先引用System.Net.Mail;
/// </summary>
/// <param name="MailFrom">发送人Email 如demo@126.com</param>
/// <param name="MailServer">邮件服务器 如mail.126.com</param>
/// <param name="MailUserName">登陆用户名 如demo@126.com</param>
/// <param name="MailPassword">登陆密码 如123456</param>
/// <param name="mailto">收件人邮箱</param>
/// <param name="title">邮件标题</param>
/// <param name="msg">邮件正文</param>
/// <returns>成功 true; 失败 false</returns>
public static bool SendSmtpEmail(string MailFrom, string MailServer, string MailUserName, string MailPassword, string mailto, string title, string msg)
{
    var client = new SmtpClient();
    client.Host = MailServer;
    client.UseDefaultCredentials = false;
    client.Credentials = new System.Net.NetworkCredential(MailUserName, MailPassword);
    client.DeliveryMethod = SmtpDeliveryMethod.Network;
    System.Net.Mail.MailMessage message = new MailMessage(MailFrom, mailto);
    message.Subject = title;
    message.Body = msg;
    message.SubjectEncoding = System.Text.Encoding.UTF8;
    message.BodyEncoding = System.Text.Encoding.UTF8;
    message.IsBodyHtml = true;
    message.Priority = MailPriority.High;
    message.IsBodyHtml = true;
    try
    {
      client.Send(message);
      return true;
    }
    catch
    {
      return false;
    }
}
#endregion
