C#使用QQ邮箱发送邮件

首先要开通QQ邮箱的STMP服务。QQ邮箱——设置——账户——开启SMTP服务。

需要引用：

using ;

using .Mail;

using System.Text;

具体代码如下：

public static void SendEmail(string fromAddr,string psw, string toAddr,string subject, string body){MailMessage myMail = new MailMessage();myMail.From = new MailAddress(fromAddr);myMail.To.Add(new MailAddress(toAddr));myMail.Subject = subject;myMail.SubjectEncoding = Encoding.UTF8;myMail.Body = body;myMail.BodyEncoding = Encoding.UTF8;myMail.IsBodyHtml = true;SmtpClient smtp = new SmtpClient();smtp.Host = "";smtp.Credentials = new NetworkCredential(fromAddr, psw);smtp.Send(myMail);}
