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);

首先去https://myaccount.google.com/lesssecureapps，并允许不太安全的应用程序为真。
然后使用下面的代码。这下面的代码只会工作，如果你的电子邮件地址是从gmail。
static void SendEmail()
{
string mailBodyhtml =
"<p>some text here</p>";
var msg = new MailMessage("from@gmail.com", "to1@gmail.com", "Hello", mailBodyhtml);
msg.To.Add("to2@gmail.com");
msg.IsBodyHtml = true;
var smtpClient = new SmtpClient("smtp.gmail.com", 587); //**if your from email address is "from@hotmail.com" then host should be "smtp.hotmail.com"**
smtpClient.UseDefaultCredentials = true;
smtpClient.Credentials = new NetworkCredential("from@gmail.com", "password");
smtpClient.EnableSsl = true;
smtpClient.Send(msg);
Console.WriteLine("Email Sent Successfully");
}

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; }
}
邮件。寄和寄。From是只读的。将它们移动到构造函数中。
using System.Net.Mail;
...
MailMessage mail = new MailMessage("you@yourcompany.example", "user@hotmail.com");
SmtpClient client = new SmtpClient();
client.Port = 25;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = false;
client.Host = "smtp.gmail.com";
mail.Subject = "this is a test email.";
mail.Body = "this is my test email body";
client.Send(mail);
这也可以…
string your_id = "your_id@gmail.com";
string your_password = "password";
try
{
SmtpClient client = new SmtpClient
{
Host = "smtp.gmail.com",
Port = 587,
EnableSsl = true,
DeliveryMethod = SmtpDeliveryMethod.Network,
Credentials = new System.Net.NetworkCredential(your_id, your_password),
Timeout = 10000,
};
MailMessage mm = new MailMessage(your_iD, "recepient@gmail.com", "subject", "body");
client.Send(mm);
Console.WriteLine("Email Sent");
}
catch (Exception e)
{
Console.WriteLine("Could not end email\n\n"+e.ToString());
}
使用发件人和收件人的电子邮件地址初始化MailMessage。应该是这样的
string from = "codeforwin@gmail.com"; //Senders email
string to = "reciever@gmail.com"; //Receiver's email
MailMessage msg = new MailMessage(from, to);
