关于.net 邮件发送 身份验证的问题。

Question

在我们使用 .net   System.Net.Mail进行邮件发送的时候。如果邮件服务器没有启用身份验证。那么发送时通过如下代码可以发送。  /// <summary>        /// 发送邮件        /// </summary>        /// <param name="strSmtpServer">邮件服务器地址</param>        /// <param name="UserName">发送人邮件用户名</param>        /// <param name="Password">邮件密码</param>        /// <param name="strFrom">发送方邮件地址</param>        /// <param name="strto">接收方邮件地址</param>        /// <param name="strSubject">主题</param>        /// <param name="strBody">内容</param>        /// <param name="fujian">附件</param>        /// <returns>bool</returns>        public static bool SendMail(string strSmtpServer, string UserName, string Password, string strFrom, string strto, string strSubject, string strBody,string fujian)        {            try            {                System.Net.Mail.SmtpClient client = new System.Net.Mail.SmtpClient(strSmtpServer);                client.UseDefaultCredentials = true;                client.Credentials = new System.Net.NetworkCredential(UserName, Password);                client.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;                System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage(strFrom, strto, strSubject, strBody);                                message.BodyEncoding = System.Text.Encoding.GetEncoding("gb2312");                message.SubjectEncoding = System.Text.Encoding.GetEncoding("gb2312");                message.IsBodyHtml = true;                                message.Priority = System.Net.Mail.MailPriority.High;                if (!string.IsNullOrEmpty(fujian))                {                    message.Attachments.Add(new System.Net.Mail.Attachment(fujian));                }                                          client.Send(message);                return true;             }            catch (Exception)            {                return false;            }         } 如果启用了身份验证的话 这个代码好像就发布出去了。请问。如果邮件系统启用了身份验证的话。应该怎么写才能发送邮件成功

你前面不是已经指定过一次身份信息了吗?后面怎么又加一次,还把用户名写错了.

client.Credentials = new System.Net.NetworkCredential(strFrom, Password);
