Sending mail with attachment (Bitmap) from MemoryStream don't work

Ondrej

I don't kown why..., but when I adding attachment (Bitmap) from MemoryStream, it dosn't work, because I receive mail with picture, but it has 0 KB. (sorry, my bad english)

Here is my snippet code:


... 

Bitmap bmp; 

... 

MemoryStream  = new MemoryStream(); 

bmp.Save(memStream, ImageFormat.Jpeg); 

... 

ContentType contentType = new ContentType(); 

contentType.MediaType = MediaTypeNames.Image.Jpeg; 

contentType.Name = "screen"; 



MailMessage mail = new MailMessage(); 

... 

mail.Attachments.Add(new Attachment(memStream, contentType)); 

... 


SmtpClient.Send(mail);

MemoryStream memStream = new MemoryStream(); //new one

bmp.Save(memStream, ImageFormat.Jpeg); ... ContentType contentType = new ContentType(); contentType.MediaType = MediaTypeNames.Image.Jpeg; contentType.Name = "screen"; MailMessage mail = new MailMessage(); ... mail.Attachments.Add(new Attachment(memStream, contentType));

-----------------------------------------------------------------------------
memStream.Position should be set to 0 after bmp.Save(memStream, ImageFormat.Jpeg);
and then , It works.
I have met the same issue before.

Hi, Where did you define the "memStream" you created new object of MemoryStream but without to declare "memStream" there.

Bitmap bmp; ... MemoryStream = new MemoryStream(); //Old oneMemoryStream memStream = new MemoryStream(); //new one

bmp.Save(memStream, ImageFormat.Jpeg); ... ContentType contentType = new ContentType(); contentType.MediaType = MediaTypeNames.Image.Jpeg; contentType.Name = "screen"; MailMessage mail = new MailMessage(); ... mail.Attachments.Add(new Attachment(memStream, contentType)); ... SmtpClient.Send(mail);
