c# - 在C#3.5中发送电子邮件失败

发送电子邮件时，出现以下错误：


  设备尚未准备就绪，位于System.Net.Mail.SmtpClient.Send（MailMessage消息）。


代码是：

MailMessage mailMessage = new MailMessage(senderEmail, cleanRecipients)
{
    Subject = string.empty,
    Body = string.empty,
    IsBodyHtml = false
};
SmtpClient smtpClient = new SmtpClient();
smtpClient.Send(mailMessage);

最佳答案

此代码可能会有所帮助！

string from = [email protected]; //Replace this with your own correct Gmail Address

string to = [email protected] //Replace this with the Email Address to whom you want to send the mail

System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage();
 mail.To.Add(to);
 mail.From = new MailAddress(from, "One Ghost" , System.Text.Encoding.UTF8);
mail.Subject = "This is a test mail" ;
mail.SubjectEncoding = System.Text.Encoding.UTF8;
mail.Body = "This is Email Body Text";
mail.BodyEncoding = System.Text.Encoding.UTF8;
mail.IsBodyHtml = true ;
mail.Priority = MailPriority.High;

SmtpClient client = new SmtpClient();
//Add the Creddentials- use your own email id and password

 client.Credentials = new System.Net.NetworkCredential(from, "Password");

client.Port = 587; // Gmail works on this port
client.Host = "smtp.gmail.com";
client.EnableSsl = true; //Gmail works on Server Secured Layer
       try
        {
            client.Send(mail);
        }
        catch (Exception ex)
        {
            Exception ex2 = ex;
            string errorMessage = string.Empty;
            while (ex2 != null)
            {
                errorMessage += ex2.ToString();
                ex2 = ex2.InnerException;
            }
   HttpContext.Current.Response.Write(errorMessage );
        } // end try
