发送 Gmail 电子邮件
本文关键字:电子邮件 Gmail 发送 | 更新日期: 2024-10-30 23:47:50
我正在尝试通过 C# 应用程序(控制台)发送电子邮件。实际上,我希望它向任何类型的电子邮件发送电子邮件,但目前如果我能将其发送到gmail帐户,我会很高兴。
我只是想暂时能够将其发送到Gmail帐户?
整个程序:
namespace EmailAddress
{
class Program
{
static void Main(string[] args)
{
Program test = new Program();
test.email_send();
}
public void email_send()
{
MailMessage mail = new MailMessage();
SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com");
mail.From = new MailAddress("hg@gmail.com");
mail.To.Add("hg@gmail.com");
mail.Subject = "Test Mail - 1";
mail.Body = "Your attachment is accessible on your computer!";
System.Net.Mail.Attachment attachment;
attachment = new System.Net.Mail.Attachment("g:/example1.txt");
mail.Attachments.Add(attachment);
SmtpServer.Port = 587;
SmtpServer.Credentials = new System.Net.NetworkCredential("your mail@gmail.com", "your password");
SmtpServer.EnableSsl = true;
SmtpServer.Send(mail);
}
}
}
新代码:不挂起,但不会将邮件发送到收件箱
static void Main(string[] args)
{
Program test = new Program();
//test.email_send();
test.CreateTestMessage4();
}
public void email_send()
{
MailMessage mail = new MailMessage();
SmtpClient smtp = new SmtpClient("smtp.gmail.com");
mail.From = new MailAddress("g@gmail.com");
mail.To.Add("g@gmail.com");
mail.Subject = "Test Mail - 1";
mail.Body = "Your attachment is accessible on your computer!";
System.Net.Mail.Attachment attachment;
attachment = new System.Net.Mail.Attachment("g:''example1.txt");
mail.Attachments.Add(attachment);//list of attachements
smtp.Port = 587;//google standard -- most of the time wouldn't not set
smtp.EnableSsl = true;
smtp.UseDefaultCredentials = true;
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
smtp.Credentials = new System.Net.NetworkCredential("*","*");
smtp.Send(mail);
Console.WriteLine("-- Sending Email --");
Console.ReadLine();
}
有人可以尝试此代码,看看它是否有效。出于某种原因,这是行不通的,所以我希望有人对此有新的看法。我只是在类实例的主方法中调用它。
public void email_send()
{
MailMessage mail = new MailMessage();
SmtpClient smtp = new SmtpClient("smtp.gmail.com");
mail.From = new MailAddress("your email address");
mail.To.Add("your email address");
mail.Subject = "Test Mail - 1";
mail.Body = "Your attachment is accessible on your computer!";
System.Net.Mail.Attachment attachment;
attachment = new System.Net.Mail.Attachment("g:''example1.txt");
mail.Attachments.Add(attachment);//list of attachements
//smtp.Port = 587;//google standard -- most of the time wouldn't not set
//smtp.EnableSsl = true;
//smtp.UseDefaultCredentials = true;
//smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
//smtp.Credentials = new System.Net.NetworkCredential("your address",
"your password");
smtp.Port = 587;
smtp.Host = "smtp.gmail.com";
smtp.UseDefaultCredentials = false;
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
smtp.EnableSsl = true;
smtp.Credentials = new System.Net.NetworkCredential("*", "*"); smtp.Send(mail);
Console.WriteLine("-- Sending Email --");
Console.ReadLine();
}
你的代码很接近:
MailMessage mail = new MailMessage();
using (SmtpClient smtp = new SmtpClient("smtp.gmail.com")) {
mail.From = new MailAddress("haufdoug@gmail.com");
mail.To.Add("haufdoug@gmail.com");
mail.Subject = "Test Mail - 1";
mail.Body = "Your attachment is accessible on your computer!";
System.Net.Mail.Attachment attachment;
attachment = new System.Net.Mail.Attachment("g:''example1.txt");
mail.Attachments.Add(attachment);
smtp.Port = 587;
smtp.EnableSsl = true;
smtp.UseDefaultCredentials = false;
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
smtp.Credentials = new System.Net.NetworkCredential("your mail@gmail.com", "your password");
smtp.Send(mail);
}
现在,关于你的其他一些问题。
端口 587 仅供 Google 使用。 通常,您连接的邮件服务器会告诉您用于SMTP邮件的端口;谷歌说他们的是587。
对于通过其他服务器发送,您通常不会设置端口号。
旁注:
- SmtpClient 实现了 IDisposable 接口。 因此,它应该包装在 using 子句中,以确保它在完成时得到正确处置。 除非您使用的是
.SendAsync()
方法。 - 我将变量名称从
SmtpServer
更改为smtp
有两个原因。 首先,命名约定。 方法中的变量建议为驼峰大小写(例如)。 其次,SmtpServer 用词不当,因为对象是SmtpClient
。 这些都是非常不同的事情,错误命名只是不好的做法。
你能试试这个吗,它对我有用:
SmtpClient SmtpServer = new SmtpClient();
SmtpServer.Port = 587;
SmtpServer.Host = smtp.gmail.com;
SmtpServer.UseDefaultCredentials = false;
SmtpServer.DeliveryMethod = SmtpDeliveryMethod.Network;
SmtpServer.EnableSsl = true;
SmtpServer.Credentials = new System.Net.NetworkCredential("your mail@gmail.com", "your password");
