第一种发送方式
```
public bool SendEmail(string UserEmail, string randcode)
{
string SendEmail = "邮箱账号";
string SendPwd = "邮箱密码/验证方式，具体查看下图";
SmtpClient _smtpClient = new SmtpClient();
_smtpClient.EnableSsl = true;
_smtpClient.UseDefaultCredentials = false;
_smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
_smtpClient.Host = "smtp.qq.com";
_smtpClient.Port = 587;
_smtpClient.Credentials = new System.Net.NetworkCredential(SendEmail, SendPwd);
//密码不是QQ密码，是qq账户设置里面的POP3/SMTP服务生成的key
MailMessage _mailMessage = new MailMessage(SendEmail, UserEmail);
_mailMessage.Subject = "";//主题
_mailMessage.Body = "";//邮件正文
_mailMessage.BodyEncoding = Encoding.Default;//正文编码
_mailMessage.IsBodyHtml = true;//设置为HTML格式
_mailMessage.Priority = MailPriority.High;//优先级
try
{
_smtpClient.Send(_mailMessage);
Console.WriteLine("发送成功");
return true;
}
catch (Exception e)
{
Console.WriteLine("发送失败");
throw e;
}
}
```
第二种方式
需要引用CDO组件发送，Interop.CDO和Interop.ADODB
但是记住 CDO引用嵌入式必须修改为false否则会提示错误。
