Question

我正在尝试发送电子邮件，但收到以下错误：

尝试以其访问权限禁止的方式访问套接字72.52.4.90:587

代码：

var mail = new MailMessage();
var 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 NetworkCredential("myemail@gmail.com", "password");

mail.From = new MailAddress("myemail@gmail.com");
mail.To.Add(new MailAddress("myemail@gmail.com"));
mail.BodyEncoding = UTF8Encoding.UTF8;
mail.DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure; 
mail.Subject = "this is a test email.";
mail.Body = "this is my test email body";
client.Send(mail);

注意：此代码基于StackOverflow中已有的其他问题和答案。然而，经过广泛搜索后，似乎到目前为止还没有其他人遇到过这个问题。根据另一个Q＆amp; A，此代码应该正常工作。

更新：在被告知这是重复之后，我已将代码修改为以下内容，但是，我仍然遇到同样的错误。

    private static void Main(string[] args)
    {
        var From = new MailAddress("myemail@gmail.com", "Me");
        var To = new MailAddress("myemail@gmail.com", "Me Too");
        var client = new SmtpClient
        {
            Host = "smtp.gmail.com",
            Port = 587, //25
            EnableSsl = true,
            DeliveryMethod = SmtpDeliveryMethod.Network,
            UseDefaultCredentials = false,
            Credentials = new NetworkCredential(From.Address, "password"),
            Timeout = 20000
        };

        using (var mail = new MailMessage(From, To)
        {
            Subject = @"this is a test email.",
            Body = @"this is my test email body"
        })
        {
            client.Send(mail);
        };
    }

使用C＃通过GMail发送电子邮件失败
