关键是解决问题，别给我贴烂东西
if (BalloonShopConfiguration.EnableErrorLogEmail)

string from = "[e-mail]";
string to = BalloonShopConfiguration.ErrorLogEmail;
string subject = "错误报告!";//BalloonShopConfiguration.SiteName +
string body = errorMessage;
SendMail(from, to, subject, body);

异常详细信息: System.FormatException: 指定字符串与电子邮件地址所要求的形式不符。

这么明显的提示:格式错误,建议你用正则表达式验证你的email地址
这种错误要跟踪堆栈干嘛?debug下就行了,肯定是你传的参数(from,to)有问题!

给你个表达式:
验证Email地址：“^w+[-+.]w+)*@w+([-.]w+)*.w+([-.]w+)*$”

还有那最后一句话真的很欠鄙视! 参考技术A MailMessage mailMessage = new MailMessage(from,to, subject, body);

把你的 from， to 的值贴出来看看 参考技术B ...看不懂

C#和ASP.NET通过Gmail账户发送邮件的代码

开发之余，把开发过程中比较常用的代码片段备份一次，下面的代码段是关于C#和ASP.NET通过Gmail账户发送邮件的代码，希望对大家有所用途。

using System.Web.Mail;
using System;
public class MailSender
{
public static bool SendEmail(
string pGmailEmail,
string pGmailPassword,
string pTo,
string pSubject,
string pBody,
System.Web.Mail.MailFormat pFormat,
string pAttachmentPath)
{
try
{
System.Web.Mail.MailMessage myMail = new System.Web.Mail.MailMessage();
myMail.Fields.Add
"smtp.gmail.com");
myMail.Fields.Add
"465");
myMail.Fields.Add
"2");

myMail.Fields.Add
myMail.Fields.Add
pGmailEmail);
myMail.Fields.Add
pGmailPassword);
myMail.Fields.Add
"true");
myMail.From = pGmailEmail;
myMail.To = pTo;
myMail.Subject = pSubject;
myMail.BodyFormat = pFormat;
myMail.Body = pBody;
if (pAttachmentPath.Trim() != "")
{
MailAttachment MyAttachment =
new MailAttachment(pAttachmentPath);
myMail.Attachments.Add(MyAttachment);
myMail.Priority = System.Web.Mail.MailPriority.High;
}

System.Web.Mail.SmtpMail.SmtpServer = "smtp.gmail.com:465";
System.Web.Mail.SmtpMail.Send(myMail);
return true;
}
catch (Exception ex)
{
throw;
}
}
}

 

EmailLib.SendEmail.SendEmail("your_gmail_id",
"your_gmail_password",
"[email protected]",
"This is email subject" ,
"This is email body",
Web.Mail.MailFormat.Text,
"Physical path to your Attachment")
