将docx转换成pdf

Question

My documents are stored in a database that I want to send mail with attachments.

I want to convert stored docx to pdf.

var result = from c in valinor.documents
             select new
             {
                 c.document_name,
                 c.document_size,
                 c.document_content
             };

var kk = result.ToList();
for (int i = 0; i<kk.Count; i++)
{
    MemoryStream stream = new MemoryStream(kk[i].document_content);
    Attachment attachment = new Attachment(stream, kk[i].document_name + ".pdf", "application/pdf");
    mail.Attachments.Add(attachment);
}

How can I convert document_content to pdf?

Answer 1

You need to use Microsoft.Office.Interop.Word in MIcrosoft office dll.

• add reference to your project Microsoft.Office.Interop.Word
• Check my sample of Code.

It's nice and Easy. 100% work for me.

Microsoft.Office.Interop.Word.Application word = new Microsoft.Office.Interop.Word.Application();   
wordDocument = word.Documents.Open(savedFileName, ReadOnly: true);
wordDocument.ExportAsFixedFormat(attahcmentPath + "/pdf" + attachment.BetAttachmentCode + ".pdf", Microsoft.Office.Interop.Word.WdExportFormat.wdExportFormatPDF);
word.Quit(false);

您将需要在计算机上安装第三方组件，例如ABCpdf和（可能）Word，然后使用该组件将docx转换为pdf。
