In SharePoint 2013 i was convert the .doc and .docx document to PDF.

when we are converting to PDF in document library we are storing some field values like ContractID, DocumentType.

converting .docx document to PDF that time ContractID, DocumentType is stored in Document Library.

But when converting .doc document to PDF list time ContractID, DocumentType is not stored in Document Library.

Here is my code :

Document.cs

                        SPQuery oQry = new SPQuery();
                        oQry.Query = "<Where><And><Eq><FieldRef Name='ContractID' /><Value Type='Lookup'>" + ContractID + "</Value></Eq><Eq><FieldRef Name='ID' /><Value Type='Counter'>" + DocID + "</Value></Eq></And></Where>";
                        oQry.ViewAttributes = "Scope='RecursiveAll'";
                        SPListItemCollection ocol = oDocLib.GetItems(oQry);
                        //SPListItem oTempItem = olist.GetItemById(ContractID);
                        SPListItem oTempItem = ocol[0];
                        string url = string.Empty;
                        string FileUrl = oTempItem.Url;
                        int fileExtPos = FileUrl.LastIndexOf(".");
                        if (fileExtPos >= 0)
                            url = FileUrl.Substring(0, fileExtPos);
                        SPFile oFile = oTempItem.File;
                       oFile.Web.AllowUnsafeUpdates = true;
                        // oFile.MoveTo(oFile.ParentFolder + "/" + docName+".pdf", true);
                        // oTempItem.File.MoveTo(url + ".pdf", true); 
                        //still this step in oFile ContractID is there.(oFile.MoveTo(url + ".pdf", //true);)
                        //in this step while converting pdf ContractID become null.

                        oFile.MoveTo(url + ".pdf", true);
                        oFile.SaveBinary(data1);
                        oFile.Update();



                    }
                }
            });
        }
        catch (Exception ex)
        {
            ex.ToString();
        }
    }

As far as i know, document properties promotion and demotion does not happen for Office 2003 documents. So the properties are not demoted for the doc file and hence the list columns loose the values after converting document to pdf. For detailed explanation, please refer to this article.

As an alternative/workaround, you can store the required metadata to be updated in some variable(s) and after the document is converted successfully to pdf, you can fetch the corresponding list item using the new document URL and update the required metadata explicitly. This would be needed only for Office 2003 documents.

Code to update the list item associated with the document

//Store the contract id in temporary variable
var contractId = oTempItem["contractID"]
string fileUrl = url + ".pdf";
//Move the file
oFile.MoveTo(fileUrl, true);
oFile.SaveBinary(data1);
oFile.Update();
// Get the list item.
SPListItem fileItem = web.GetListItem(fileUrl);
//Update required fields
fileItem["contractID"] = contractId;
fileItem.Update();

you can download WrodToPDF dll and include the same in event receiver in itemadded event, check extension of added file, if it resembles with doc or docx just convert it and then add using the dll,
