Hello
When I’m trying to convert the MSG File I’ve got a System.NullReferenceException when I try to manipulate Aspose.Words.Document (property PageCount). But only when mhtOptions.SkipInlineImages is true.
I’m using Aspose .NET (Aspose.Email 24.11.0.0 / Aspose.Words 24.12.0.0)
Here is the code I use to convert a MSG File to PDF :
- firstPageIndex & pageCount = 0
- withImagesFromMsg = 1

public static int Convert(string inputFile, string outputFile, ref string errmsg, int firstPageIndex, int pageCount, int withImagesFromMsg)
{
errmsg = "";
try
{
FileStream docStream = new FileStream(inputFile, FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
try
{
MemoryStream ms = new MemoryStream();
MhtSaveOptions mhtOptions = Aspose.Email.SaveOptions.DefaultMhtml; //new Aspose.Email.MhtSaveOptions();
// mhtOptions.MhtFormatOptions = MhtFormatOptions.WriteHeader | MhtFormatOptions.WriteCompleteEmailAddress | MhtFormatOptions.RenderCalendarEvent | MhtFormatOptions.DisplayAsOutlook | MhtFormatOptions.RenderTaskFields | MhtFormatOptions.RenderVCardInfo;
mhtOptions.MhtFormatOptions = MhtFormatOptions.WriteHeader | MhtFormatOptions.WriteCompleteEmailAddress | MhtFormatOptions.RenderCalendarEvent | MhtFormatOptions.RenderTaskFields | MhtFormatOptions.RenderVCardInfo;
mhtOptions.SkipInlineImages = (withImagesFromMsg != 1);
// If mail date is to be printed according to the local system timezone,
// subtract the mail timezone offset from mail date and add your local system timezone
TimeZone localZone = TimeZone.CurrentTimeZone;
TimeSpan ts = localZone.GetUtcOffset(DateTime.Now);
CultureInfo culture = new CultureInfo("fr-FR");
string ext = Path.GetExtension(inputFile).ToLower();
if (ext == ".eml")
{
var message = MailMessage.Load(docStream); // eml
message.TimeZoneOffset = localZone.GetUtcOffset(message.Date.ToLocalTime());
message.Save(ms, mhtOptions);
}
else
{
var mapiMessage = MapiMessage.Load(docStream, new MsgLoadOptions());
string date = (mapiMessage.ClientSubmitTime.ToUniversalTime() + ts).ToString("ddd, dd MMM yyyy HH:mm:ss", CultureInfo.InvariantCulture);
string newDate = ResetUTCOffset(date, ts);
mapiMessage.Headers["Date"] = newDate;
