我不明白为什么这个代码不能工作。我得到一个错误,说属性不能被分配
MailMessage mail = new MailMessage();
SmtpClient client = new SmtpClient();
client.Port = 25;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = false;
client.Host = "smtp.gmail.com";
mail.To = "user@hotmail.com"; // <-- this one
mail.From = "you@yourcompany.example";
mail.Subject = "this is a test email.";
mail.Body = "this is my test email body";
client.Send(mail);
到2017年3月,这对我来说是有效的。
从上面的解决方案开始:“终于开始工作了:)”,一开始并没有工作。
SmtpClient client = new SmtpClient();
client.Port = 587;
client.Host = "smtp.gmail.com";
client.EnableSsl = true;
client.Timeout = 10000;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = false;
client.Credentials = new System.Net.NetworkCredential("<me>@gmail.com", "<my pw>");
MailMessage mm = new MailMessage(from_addr_text, to_addr_text, msg_subject, msg_body);
mm.BodyEncoding = UTF8Encoding.UTF8;
mm.DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure;
client.Send(mm);
这个答案的特点是:
尽可能使用“Using”(IDisposable接口)
使用对象初始化器
异步编程
将SmtpConfig提取到外部类(根据需要进行调整)
下面是提取的代码:
public async Task SendAsync(string subject, string body, string to)
{
using (var message = new MailMessage(smtpConfig.FromAddress, to)
{
Subject = subject,
Body = body,
IsBodyHtml = true
})
{
using (var client = new SmtpClient()
{
Port = smtpConfig.Port,
DeliveryMethod = SmtpDeliveryMethod.Network,
UseDefaultCredentials = false,
Host = smtpConfig.Host,
Credentials = new NetworkCredential(smtpConfig.User, smtpConfig.Password),
})
{
await client.SendMailAsync(message);
}
}
}
Class SmtpConfig:
public class SmtpConfig
{
public string Host { get; set; }
public string User { get; set; }
public string Password { get; set; }
public int Port { get; set; }
public string FromAddress { get; set; }
}
