I'm having problems, while sending multiple attachments in my program.
I didn't have any problems before I tried to add multiple attachments. So I changed to code a bit and it stopped working.
Create attachment: Didn't add all the code to make it more viewable.
Attachment attachment = getAttachment(bodyFile, "Formulier" + counter + ".doc");
attachments.Add(attachment);
//attachment.Dispose();
if (attachments != null)
{
foreach (Attachment attachment in attachments)
{
email.Attachments.Add(attachment);
}
}
Get Attachment
private Attachment getAttachment(string bodyFile, string title)
{
return createDocument(bodyFile, title);
}
Creating file
private Attachment createDocument(string bodyFile, string title)
{
string activeDir = HttpContext.Current.Server.MapPath("/Tools");
string newPath = Path.Combine(activeDir, "Documents");
Directory.CreateDirectory(newPath);
newPath = Path.Combine(newPath, title);
FileStream fs = File.Create(newPath);
fs.Close();
File.WriteAllText(newPath, bodyFile);
var fstemp = new FileStream(newPath, FileMode.Open, FileAccess.Read);
return new Attachment(fstemp, title, MediaTypeNames.Application.Octet);
}
The error I get in my logger
2012-07-04 15:45:26,149 [19] ERROR Mvc - System.Net.Mail.SmtpException: Failure sending mail. ---> System.ObjectDisposedException: Cannot access a closed file.

EDIT
I got rid of the .Dispose method and changed var fstemp = new FileStream(newPath ...
Now I can send multiple attachments. But now they randomly give an error or not. 4 out of 5 times it works. 4th time it gives an error again that it can't open the file. 5th time it magicly works again.
EDIT: Solution
I used a using block in combination with two answers. And that worked. Tnx to @HatSoft and @Aghilas Yakoub
Try it with these lines (in your CreateDocument
method):
var fstemp = new FileStream(newPath, FileMode.Open, FileAccess.Read);
return new Attachment(fstemp, title, MediaTypeNames.Application.Octet);
