Attachment problem

[eusebiu]

hello...

Let`s say that we have the following C# code :

using(MemoryStream imageStream = new MemoryStream())
            {
                //create a bitmap image
                Bitmap b = graphBuilder.BuildImageGraph(...);
                b.Save(imageStream,System.Drawing.Imaging.ImageFormat.Jpeg);
               
                EmailMessage emailMessage = new EmailMessage();
                //email details
                //...
                FileAttachment relatedFileAttachment = new FileAttachment(imageStream.GetBuffer(), "a1");
                emailMessage.AddRelatedAttachment( relatedFileAttachment );
               
                SmtpServer s = new SmtpServer("localhost");
            }

When I verify my e-mail , i get only a part of the image.

Can you tell me why I get this?

Hello...After I`ve read some of the threads , I found that my problem was solved by 'jatubio' in his thread : Corrupts Attachement!!!

...
int charstoread=Base64Encoder.MAX_CHARS_PER_LINE * 100;

This is a problem because the base64 conversion works on groups of 3 bytes (7600 / 3 isn't an integer number!), so you get a different results than converting the whole array!
A solution could be to convert the whole array all at once or to use a block size divisible by 3 (e.g. 76 * 102)

...

I`ve downloaded the sources and changed 100 with 102 and now it`s waorking!

See ya!
