我定义一个整数型j，当上传邮件附件后，j就=1，我点击发送判断j是不是>0,是的话就添加附件发送，不是的话就直接发送。为什么报错？错误信息为：命令顺序不正确。 服务器响应为: Error: need EHLO and AUTH first !
if (j > 0)
{
Attachment data = new Attachment(fileName, System.Net.Mime.MediaTypeNames.Application.Octet); //Add time stamp information for the file.
System.Net.Mime.ContentDisposition disposition = data.ContentDisposition;
disposition.CreationDate = System.IO.File.GetCreationTime(fileName);
disposition.ModificationDate = System.IO.File.GetLastWriteTime(fileName);
disposition.ReadDate = System.IO.File.GetLastAccessTime(fileName);
// Add the file attachment to this e-mail message.
Email.Attachments.Add(data);
}
放到
try
{
Client.Send(Email);
Response.Write("<script>alert('已发送成功啦');</script>");
}
前面，试试
/// <summary>
/// 指定用户邮箱发邮件
/// </summary>
/// <param name="subject">邮件主题</param>
/// <param name="content">邮件内容</param>
/// <param name="Recipient">收件人</param>
/// <param name="companyname">收件人名称</param>
/// <param name="CCFlag">是否抄送</param>
/// <returns></returns>
public static bool EnSystemMail(string subject, string content, string Recipient, string companyname,bool CCFlag)
{
System.Net.Mail.SmtpClient client = new SmtpClient();
client.Host = "mail.XXXX.cc";
client.UseDefaultCredentials = false;
client.Credentials = new System.Net.NetworkCredential("[email protected]","yaXX");
client.DeliveryMethod = SmtpDeliveryMethod.Network; client.EnableSsl = false;
client.Timeout = 100000; System.Net.Mail.MailMessage message = new MailMessage(); message.From = new MailAddress("[email protected]", "上XXX司");//发送方 message.To.Add(new MailAddress(Recipient,companyname)); //接收方 if (CCFlag)
{
message.CC.Add(new MailAddress("[email protected]", "染料展项目组"));
}
message.Subject = subject;
message.Body = content;
message.BodyEncoding = System.Text.Encoding.UTF8;
message.IsBodyHtml = true; try
{
client.Send(message); return true;
}
catch
{
return false;
} }
参考下吧.
不懂你的意思，我不是放在try语句块的前面了么？ 是让我放入try语句的里面？
把
if (j > 0)
{
Attachment data = new Attachment(fileName, System.Net.Mime.MediaTypeNames.Application.Octet); //Add time stamp information for the file.
System.Net.Mime.ContentDisposition disposition = data.ContentDisposition;
disposition.CreationDate = System.IO.File.GetCreationTime(fileName);
disposition.ModificationDate = System.IO.File.GetLastWriteTime(fileName);
disposition.ReadDate = System.IO.File.GetLastAccessTime(fileName);
// Add the file attachment to this e-mail message.
Email.Attachments.Add(data);
}
放到
//处理待发的电子邮件的方法 (Delivery 发送,传输)
Client.DeliveryMethod = SmtpDeliveryMethod.Network;
后面
if (j > 0)
{
Attachment data = new Attachment(fileName, System.Net.Mime.MediaTypeNames.Application.Octet);//Add time stamp information for the file.
System.Net.Mime.ContentDisposition disposition = data.ContentDisposition;
disposition.CreationDate = System.IO.File.GetCreationTime(fileName);
disposition.ModificationDate = System.IO.File.GetLastWriteTime(fileName);
disposition.ReadDate = System.IO.File.GetLastAccessTime(fileName);
// Add the file attachment to this e-mail message.
Email.Attachments.Add(data);
}
注销了，发送邮件还是报错，为什么啊？
disposition.ModificationDate = System.IO.File.GetLastWriteTime(fileName);
disposition.ReadDate = System.IO.File.GetLastAccessTime(fileName);
这3个方法哪个是保存邮件名称的啊？
