.net - C# MailMessage to stream - encoding issue -

iam using amazon ses sendrawemail api hence need mailmessage memorystream.

i have found several answers mailmessage memorystream issue here on stackoverflow.

solution 1: using 1 uses private methods results in wrong encoding of parts of email: https://stackoverflow.com/a/8826833

solution 2: no encoding problems using solution send pickup directory , read in: https://stackoverflow.com/a/14350088

i dislike fact need write temporary file make work correctly. have idea how pure memorystream solution can mess of encoding.

the mail message iam testing this:

var mailmessage = new mailmessage(); mailmessage.subject = "header special ÆØÅ"; mailmessage.body = "test";  attachment att = new attachment(@"c:\attachmentwithspecial ÆØÅ.pdf"); mailmessage.attachments.add(att); mailmessage.from = new mailaddress("test@test.com", "nameÆØÅ"); mailmessage.to.add(new mailaddress("test@test.com", "nameÆØÅ")); 

to summarize:

• if send message standard smtp looks good.
• if send using sendrawemail looks if generated memorystream using solution 2
• if send using sendrawemail has encoding issues if generated memorystream using solution 1.

with encoding issues mean 'ø' showing

did try explicitly specify encoding subject / body , mailaddress?

• body: http://msdn.microsoft.com/en-us/library/system.net.mail.mailmessage.bodyencoding.aspx
• subject: http://msdn.microsoft.com/en-us/library/system.net.mail.mailmessage.subjectencoding.aspx
• each mail address: http://msdn.microsoft.com/en-us/library/f52hswkf.aspx

i guess when .net writes mails folder can somehow define right encoding (or maybe file reader somehow can find right encoding convert data). , in memory in default encoding, not work you.
