我正在尝试使用C#框架创建一个小应用程序来发送电子邮件.但是,它不起作用.该应用程序总是给我“操作超时”.我不是为什么.
这是我的代码：
private void button1_Click(object sender,EventArgs e)
{
MailAddress fromAddress = new MailAddress("from@gmail.com");
MailAddress toAddress = new MailAddress("to@gmail.com");
MailMessage mail = new MailMessage(fromAddress.Address,toAddress.Address);
mail.Subject = "Testing";
mail.Body = "contents.";
SmtpClient client = new SmtpClient();
client.Host = "smtp.gmail.com";
client.Port = 587;
client.EnableSsl = true;
client.Timeout = 100;
client.UseDefaultCredentials = false;
client.Credentials = new NetworkCredential("username","password");
try
{
client.Send(mail);
MessageBox.Show("Mail Sent!","Success",MessageBoxButtons.OK);
}
catch (Exception ex)
{
MessageBox.Show(ex.Message,"Error",MessageBoxButtons.OK);
}
}
谢谢！
解决方法
尝试设置更高的超时限制.它是以毫秒为单位.

{

{

}
private void button1_Click(object sender,EventArgs e)
{
MailAddress fromAddress = new MailAddress("myusername@gmail.com");
MailAddress toAddress = new MailAddress("myusername@gmail.com");
MailMessage mail = new MailMessage(fromAddress.Address,toAddress.Address);
mail.Subject = "Testing";
mail.Body = "contents.";
SmtpClient client = new SmtpClient();
client.Host = "smtp.gmail.com";
client.Port = 587;
client.EnableSsl = true;
client.Timeout = 10000;
client.UseDefaultCredentials = false;
client.Credentials = new NetworkCredential("myusername","mypassword");
try
{

MessageBox.Show("Mail Sent!",MessageBoxButtons.OK);
}
catch (Exception ex)
{
MessageBox.Show(ex.Message,MessageBoxButtons.OK);
}
}
}
}
