MvcMailer，查找电子邮件的文件名

Question

我正在使用 MvcMailer 将电子邮件保存到我的 asp.net mvc Web 应用程序中本地的指定目录。但是，我想将电子邮件的文件名(例如 90b871cd-038f-400a-b4d7-01f87e8c3c26.eml(保存在数据库中，稍后将使用另一个 exe 访问该文件名以从拾取文件夹发送电子邮件。

您能否告诉我如何从邮件对象中检索文件名？

var mail = Mailer.Example_Mail()
mail.To.Add("[e-mail]");
mail.Send();
<smtp from="[e-mail]" deliveryMethod="SpecifiedPickupDirectory">
<network host="localhost" />
<specifiedPickupDirectory pickupDirectoryLocation="c:temp" />
</smtp>

提前感谢！

我认为这对寻求相同问题的答案的人可能会有所帮助。我设法克服了编写System.Net.Mail.MailMessage.Send((反射的问题，如下所示。

public static string SaveToTemp(this MailMessage Message)
{
SmtpClient smtp = new SmtpClient();
string fileName = Guid.NewGuid().ToString() + ".eml";
string fileNameWithPath = Path.Combine(smtp.PickupDirectoryLocation, fileName);
Assembly assembly = typeof(SmtpClient).Assembly;
Type _mailWriterType = assembly.GetType("System.Net.Mail.MailWriter");
using (FileStream _fileStream = new FileStream(fileNameWithPath, FileMode.Create))
{
// Get reflection info for MailWriter contructor
ConstructorInfo _mailWriterContructor =
_mailWriterType.GetConstructor(
BindingFlags.Instance | BindingFlags.NonPublic,
null,
new Type[] { typeof(Stream) }, 
null);
// Construct MailWriter object with our FileStream
object _mailWriter = _mailWriterContructor.Invoke(new object[] { _fileStream });
// Get reflection info for Send() method on MailMessage
MethodInfo _sendMethod =
typeof(MailMessage).GetMethod(
"Send",
BindingFlags.Instance | BindingFlags.NonPublic);
// Call method passing in MailWriter
_sendMethod.Invoke(
Message,
BindingFlags.Instance | BindingFlags.NonPublic,
null,
new object[] { _mailWriter,true, true },
null);
// Finally get reflection info for Close() method on our MailWriter
MethodInfo _closeMethod =
_mailWriter.GetType().GetMethod(
"Close",
BindingFlags.Instance | BindingFlags.NonPublic);
// Call close method
_closeMethod.Invoke(
_mailWriter,
BindingFlags.Instance | BindingFlags.NonPublic,
null,
new object[] { },
null);
}
return fileNameWithPath;
}

var mail = Mailer.Example_Mail()
mail.To.Add("[e-mail]");
var fileName = mail.SaveToTemp(); // Instead of mail.Send();
