How do I send an email with attachments?

To send an email with attachments, the ASP.NET process (or the ASP.NET impersonated account) will need permission to read the file, and attach it to the MailMessage class.

Note: Attachments can only be created from files on the file system. System.Web.Mail does not support creating attachments directly from strings, byte arrays, streams, or from uploaded files. To directly create attachments from these types, use aspNetEmail, otherwise, the attachment contents must first be saved to the file system.

The following example demonstrates adding the file "test.txt" as an attachment to a MailMessage.

[ C# ]

MailMessage mail = new MailMessage();
mail.To = "me@mycompany.com";
mail.From = "you@yourcompany.com";
mail.Subject = "this is a test email.";
mail.Body = "this is my test email body.";
MailAttachment attachment = new MailAttachment( Server.MapPath( "test.txt" ) ); //create the attachment
mail.Attachments.Add( attachment );	//add the attachment
SmtpMail.SmtpServer = "localhost";  //your real server goes here
SmtpMail.Send( mail );

[ VB.NET ]

Dim mail As New MailMessage()
mail.To = "me@mycompany.com"
mail.From = "you@yourcompany.com"
mail.Subject = "this is a test email."
mail.Body = "this is my test email body."
Dim attachment As New MailAttachment(Server.MapPath("test.txt")) 'create the attachment
mail.Attachments.Add(attachment) 'add the attachment
SmtpMail.SmtpServer = "localhost" 'your real server goes here
SmtpMail.Send(mail)

 "C:\\sample.Txt"
 
 dave wanta [ dave ( at ) 123aspx dot com ], 2004-05-04 18:40:45 #
 - RE RE: Invalid Email Attachment [ Reply ]
 C:Test.txt actualy should be a valid file name.
 
 C: is the Drive Spec
 
 "Test.Txt" is a FIle Spec.
 
 C:Test.txt is valid *IF* the file is in the CWD at the time!
 
 Ex:
 C:
 CD \
 DIR
 ... Test.Txt
 
 C:\>MORE C:Test.Txt
 
 the more command executes correctly.
 
 this can be used for example if you go to say E:
 cd \foo\bar\bin
 C:
 E:MyProg.exe
 
 MyProg in the CWD of E: drive will run.
 no need to enter:
 E:\foo\bar\bin\MyProg.exe
 to run it.

 remember, the code is executing server side, so the path you entered must be a valid server side path. You may need to first upload the file to the server, then email it.
 
 before you try adding the attachment, you may want to try code like:
 
 if( !File.Exists( Server.MapPath( path ) ) )
 Response.Write( " An invalid path was entered." );
 else
 //add the attachment

 John Bernhard [ jsbernhardjr ( at ) gmail dot com ], 2008-03-27 07:13:47 #
- RE: Invalid Email Attachment [ Reply ]
 to all of you who saw this annoying error message - this is your solution :
 
 STEP 1 - MUST define server valid path
 you should apply a valid and EXISTING !! folder on the SERVER from where to get the attach file. Usually this is the Upload folder path.
 
 you should get it that way :
 string ValidServerPath = Server.MapPath(string.Empty) + @"\" + UPLOAD_FOLDER + @"\";
 
 STEP 2 - Get the valid path for the attach file
 supply the attach file name and concat it to that path, like that :
 string validServerFilePath = ValidServerPath + sAttachedFileName;
 
 STEP 3 - Set encoding - IMPORTANT !!
 you have to set the mail encoding to handle all types of extentions (.doc, .txt, .jpg ...)
 to do that, create the MailAttachment object like that :
 MailAttachment fileAttachment = new MailAttachment(validServerFilePath, MailEncoding.UUEncode);
 
 STEP 4 - Attach the file to the message
 myMsg.Attachments.Add(fileAttachment);

 - RE RE: Invalid Email Attachment [ Reply ]
 This can also be caused by a file system permissins problem. My guess is that you placed this file in the folder AFTER you made the solution. Go to 'My Computer', right click and bring up properties. Click the 'Security' tab and make sure that the ASPNET account, IUSR_<machine name> account, or whatever account your site is urnning under has permissions on the file. Right clicking on it ni the project explorer (in Visual Studio) and selecting 'Include in Project' should do the same.

Attachment Size Limit? [ Reply ]
I am using SMTP Mail Service running under IIS on win2k server to send word/excel/pdf/etc files as attachments from several in house applications (windows forms and web apps) using following code;
.Attachments.Add(New Mail.MailAttachment(sFullPath, Mail.MailEncoding.UUEncode))
There appears to be a limit to the size that a standard user can send. When I log in as administrator (or a user who is in administrators group) I can use the apps to send attachments > 100kb. When logged in as a standard user, the message is sent ok, but when the attachment is opened by recipient, the attached file is empty! The message size limit in SMPT Virtual Server properties under IIS is set to 2048. I changed this to 10 to test and the apps failed to even send the message. So it appears some setting on the server is 'emptying' attachments > 100 kb for non-administrator users. Or somehting like that... Any solutions to this problem?

 I had this same problem, and the way I solved it was this...
 
 We have a web service that creates and sends all the emails.
 
 In the web.config file for that web service, we impersonate a domain user who we made an administrator on the web server local machine.
 
 It's not the best solution, but it's the only one we could get to work.

exception leaving attachment locked [ Reply ]
I am using essentially the same code as the example to send an attachement. The attachement works fine in the normal case but if the call to SmtpMail.Send gets an exception (SMTP password is bad), it seems to leave the attached file open and therefore locked.

Has anyone else seen this? Any ideas on a solution?

Thanks!

  I found the same problem. When trying to send a Mail with attachment and e.g. the password was set wrong, the attched file is locked and can't be overwritten which is really bad.
  
  Work arround could be to attach a temporary file where each time an other one is used for attachments. But that is not very elegant.
  
  Has anybody a better solution?

      Yes, I ahve the same problem. If the email send OK it frees the attachment, if it fails it locks the attachment and, since in my program this is an error log which is being constantly accessed, this causes me a problem. I tried the tempory file and copy over idea but that just got locked as well.

        Perfect solution.

Cannot attach a file that I can copy [ Reply ]
Hello,

I'm able to create a file (file1) then copy the file to a new filename using filecopy(file1, file2). Because I can write and read file1, and write the new file2 to a virtual directory I'm assuming I have proper rights.

File1 was created with server.mappath()
file2 also was created with server.mappath()

After the filecopy I try to add file2 as a mail attachment, then add the rest of the mail values (to, from, body).

I then try to send the email. But no email sends at all. I do not get any error messages.

Any Ideas?

One thing I learnted is this same code used to work 3 months ago, but just stopped for some reason (I'm new on the job here).

Any advice is welcome!!! -- rodney :)

Invalid mail attachment (images only) [ Reply ]
I'm getting an Invalid mail attachment error when I try to attach image files, but have no problem attaching Word .doc files. Could this be happening because permissions for the ASP.NET process are configured for some file types, but not others? If so, how do I set permissions for the ASP.NET process? Thanks in advance.

- RE: Invalid mail attachment (images only) [ Reply ]
  I did figure out how to add the ASPNET user to the applicable directory via IIS. I gave the ASPNET user Full Control permissions. Didn't help. Still getting the invalid mail attachment error for image files. I do not get this error for Word .doc files (so it's not a problem with the file path). Would appreciate any insight you may have.

File with Attachment sits in Queue [ Reply ]
We are sending messages using Win32 Service build using .NET and C#. System.Web.Mail. If I send email it goes through. If I send one with a ZipFile as an attachment, I get no error when I do send, but it sits in the IIS SMTP Queue. I have reviewed the logs, and I can see where it connects to the remote server, but nothing gets sent. So we told it to encode UUEncode like below:

private void SendEmail(string ToAddress, string FromAddress, string Subject, MailFormat MailType, string Message, string SmtpServer, string ZipFile)
{
//send debit email notification
try
{
// Create a New Message
MailMessage oMsg = new MailMessage();

// From E-Mail Address
oMsg.From = FromAddress;

// To E-Mail Address
oMsg.To = ToAddress;

// Create A Subject
//
oMsg.Subject = Subject;

// Set text format
oMsg.BodyFormat = MailType;

//add an attachment

if (!File.Exists(ZipFile))
return;
// FileStream fs=null;
try
{
MailAttachment MailAttach = new MailAttachment(ZipFile,MailEncoding.UUEncode);

oMsg.Attachments.Add(MailAttach);
}
catch(Exception ex)
{
ExceptionManager.Publish(ex);
}

// Message body
oMsg.Body = Message;

// SMTP server.
SmtpMail.SmtpServer = SmtpServer;

SmtpMail.Send(oMsg);
}
catch(Exception ex)
{
ExceptionManager.Publish(ex);
}
}

When we do the mail goes through but it comes across on the other end not at as a file but like so

sending image as stream inside email-body [ Reply ]
i need to to create a code, that sends an image inside a mail. the problem is: the image stays only for 20 minutes on the server. so, sending the image as a normal attachement won't help a lot as in most cases, the image will already be deleted by time the client reads his mail...

so i thought about reading the image to a memorystream and sending this stream inside the body of the mail.

has anybody an idea, how this could be done?

best regards

Problem: HTML email body and encoded attachment [ Reply ]
Hi all,
My code is like:

MailMessage mail = new MailMessage();
mail.To = "me@mycompany.com";
mail.From = "you@yourcompany.com";
mail.Subject = "this is a test email.";

mail.BodyFormat = MailFormat.Html;
mail.Body = "this is my test email
body. this part is in bold";

// I had to use UUEncode other my attachments
// would get crrupted.
mail.Attachments.Add(new MailAttachment(filename,MailEncoding.UUEncode));

SmtpMail.SmtpServer = MY_SMTP_SERVER;
SmtpMail.Send( mail );

Now the problem is that when i receive the email the attachment is ok but the email is sent as "Plain Text" not "HTML"!
Does anyone know why?
