                    }
                    catch { }
                }
            }
        }
    }
}

实例二SmtpClient

 

 代码如下 复制代码
    //创建smtpclient对象  
    System.Net.Mail.SmtpClient client = new SmtpClient();  
    client.Host = "smtp.163.com";//163的smtp服务器是 smtp.163.com  
    string from = "***@163.com";  
    string pwd = "密码";  
    string tomail = "***@qq.com";  
     
    client.UseDefaultCredentials = false;  
    client.Credentials = new System.Net.NetworkCredential(from, pwd);  
     
    client.DeliveryMethod = SmtpDeliveryMethod.Network;  
    System.Text.Encoding encoding = System.Text.Encoding.UTF8;  
    string senderDisplayName = ConfigurationManager.AppSettings["senderDisplayName"];//这个配置的是发件人的要显示在邮件的名称  
    string recipientsDisplayName = "昊云";//这个配置的是收件人的要显示在邮件的名称  
     
    MailAddress mailfrom = new MailAddress(from, senderDisplayName, encoding);//发件人邮箱地址，名称，编码UTF8  
    MailAddress mailto = new MailAddress(tomail, recipientsDisplayName, encoding);//收件人邮箱地址，名称，编码UTF8  
    //创建mailMessage对象  
    System.Net.Mail.MailMessage message = new MailMessage(mailfrom, mailto);  
    message.Subject = "测试邮件标题";  
    //正文默认格式为html  
    message.Body = "测试邮件内容";  
    message.IsBodyHtml = true;  
    message.BodyEncoding = encoding;  
    message.SubjectEncoding = encoding;  
    message.HeadersEncoding = encoding;  
     
    client.Send(message);
