            Encoding encoding = Encoding.GetEncoding("utf-8");

            MailAddress from = new MailAddress(settings.Smtp.From, settings.Smtp.Network.UserName, encoding);

            MailMessage message = new MailMessage(from, to);
            message.SubjectEncoding = encoding;
            message.IsBodyHtml = true;
            message.Priority = MailPriority.High;
            message.Subject = "XXXXX邮箱验证激活";
            message.BodyEncoding = encoding;
            StringBuilder sb = new StringBuilder();
            sb.Append("您好:");
            sb.Append(userName);
            sb.Append("<br/>请点击下面的连接来验证激活");
            sb.Append(string.Format("<br/><a href='http://baidu.com/Index/CheckingEmailBack.aspx?SignString={0}&userName={1}'>", signString, userName));
            sb.Append(string.Format("http://baidu.com/Index/CheckingEmailBack.aspx?SignString={0}&userName={1}", signString, userName));
            sb.Append("</a>");
            //邮件主体
            message.Body = sb.ToString();
            //服务器
            SmtpClient client = new SmtpClient(settings.Smtp.Network.Host);
            //的用户名和密码
            client.Credentials = new NetworkCredential(settings.Smtp.From, settings.Smtp.Network.Password);
            client.Send(message);
        }
        catch (Exception ex)
        {
            throw new Exception(ex.Message);
        }
    }

我测试后无法成功, 这里特作两点说明

//要使用Configuration类,不仅要using System.Configuration; 还需要在引用中找到添加引用System.Configuration.dll
//要使用WebConfigurationManager,不仅要System.Web.Configuration; 还需要在引用中找到添加引用System.Web.dll
