邮件系统在服务器上注意的问题(要另外设置些东西)

cs文件里面添加一句
using System.Web.Mail
MailMessage mail = new MailMessage();
mail.From ="xiaotupansy@163.com";
mail.To="xiaotupansy@163.com";
mail.Subject = "1111111111";
mail.Body = "2222222222222";
mail.Fields["http://schemas.microsoft.com/cdo/configuration/sendusername"] = "用户名";
mail.Fields["http://schemas.microsoft.com/cdo/configuration/sendpassword"] = "密码";
mail.Fields["http://schemas.microsoft.com/cdo/configuration/smtpauthenticate"] = 1;
mail.Fields["http://schemas.microsoft.com/cdo/configuration/languagecode"] = 0x0804;
SmtpMail.SmtpServer = "smtp.163.com";
SmtpMail.Send(mail);
