如何在不使用存储的情况下将DOC或DOCX字节转换为PDF [C#]

byte[] docBytes;

using (FileStream stream = new FileStream("path/to/doc.docx", FileMode.Open))
{
    docBytes = new byte[stream.Length];
    stream.Read(docBytes, 0, (int)stream.Length);
}

using (MemoryStream input = new MemoryStream(docBytes))
{
    using (MemoryStream output = new MemoryStream())
    {
        iTextSharp.text.Document doc = new iTextSharp.text.Document();
        iTextSharp.text.pdf.PdfWriter writer = iTextSharp.text.pdf.PdfWriter.GetInstance(doc, output);
        doc.Open();
        iTextSharp.text.html.simpleparser.HTMLWorker worker = new iTextSharp.text.html.simpleparser.HTMLWorker(doc);
        worker.Parse(new MemoryStream(docBytes));
        doc.Close();
        
        byte[] pdfBytes = output.ToArray();
        
        // 这里可以对pdfBytes进行后续处理，例如保存到磁盘或发送到其他地方
    }
}
