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);
请您参考如下方法:
此代码可能会有所帮助！
string from = me@gmail.com; //Replace this with your own correct Gmail Address
string to = you@gmail.com //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
