Attachment encoding wrong

[AlexWarrior1]

Hi!

i'm working with mailkit for download invoices from inbox email, but in some cases when it download the xml it does with characters weird as show below

<cfdi:Comprobante xmlns:cfdi=3D"http://www.sat.gob.mx/cfd/4" =
xmlns:xsi=3D"http://www.w3.org/2001/XMLSchema-instance" =
xsi:schemaLocation=3D"http://www.sat.gob.mx/cfd/4 =
http://www.sat.gob.mx/sitio_internet/cfd/4/cfdv40.xsd" Version=3D"4.0" =
Fecha=3D"2023-09-22T00:00:00" Serie=3D"A" Folio=3D"5500427" =

this is the correct xml

<cfdi:Comprobante xmlns:cfdi="http://www.sat.gob.mx/cfd/4" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.sat.gob.mx/cfd/4 http://www.sat.gob.mx/sitio_internet/cfd/4/cfdv40.xsd" Version="4.0" Fecha="2023-09-22T00:00:00" Serie="A" Folio="5500427"

i'm running de app in windows, and de language is c# .Net Core
the version of mimekit is NetCore.MailKit 2.1.0

this is how i read the attachments
var attachmentStream = mimePart.Content.Stream;

  // Specify the file path where you want to save the attachment
  string filePath = "c:\\test.xml"; // Replace with your desired file path and extension

  // Use Ude to auto-detect the encoding
  var detector = new CharsetDetector();
  detector.Feed(attachmentStream);
  detector.DataEnd();

  // Get the detected encoding
  string detectedEncoding = detector.Charset;

  // Reset the attachment stream position
  attachmentStream.Seek(0, SeekOrigin.Begin);

  // Create a FileStream to write the attachment content to the file with the detected encoding
  using (var fileStream = new FileStream(filePath, FileMode.Create, FileAccess.Write))
  using (var writer = new StreamWriter(fileStream, Encoding.GetEncoding(detectedEncoding)))
  {
      // Read from the attachment stream and write it to the file stream with the detected encoding
      using (var reader = new StreamReader(attachmentStream, Encoding.GetEncoding(detectedEncoding)))
      {
          while (!reader.EndOfStream)
          {
              var line = reader.ReadLine();
              writer.WriteLine(line);
          }
      }
  }

  // Close the streams
  attachmentStream.Close();

any idea that what i am doing wrong?

thanks!

The MimePart.Content.Stream is encoded using the MimePart.Content.Encoding mechanism, so if it isn't "Default", then you need to decode it.

MimeContent has 2 ways of doing this:

1. Use the MimeContent.DecodeTo(Stream) method which decodes into an output stream.
2. Use MimeContent.Open() which returns a stream that will decode the content as you read from it.

thanks a lot!

it worked from me the first option (MimeContent.DecodeTo(Stream))

regards!
