var index = 1;
LoadOptions LoadOptionsProvider(LoadContext loadContext)
{
if (loadContext.SourceFormat == EmailFileType.Eml)
{
return new EmailLoadOptions
{
ConvertOwned = true,
ConvertOwner = true,
Depth = 2
};
}
return null;
}
Stream ConvertedStreamProvider(SaveContext saveContext)
{
string outputFile = $"converted-{index++}.{saveContext.TargetFormat.Extension}";
return new FileStream(outputFile, FileMode.Create);
}
ConvertOptions ConvertOptionsProvider(ConvertContext convertContext)
{
if (convertContext.SourceFormat == EmailFileType.Eml)
{
return new WordProcessingConvertOptions();
}
if (convertContext.SourceFormat == WordProcessingFileType.Txt)
{
return new PdfConvertOptions();
}
return new ImageConvertOptions();
}
using (var converter = new Converter("sample_with_attachments.eml", LoadOptionsProvider))
{
converter.Convert(ConvertedStreamProvider, ConvertOptionsProvider);
}
