मैं माइक्रोसॉफ्ट वर्ड में किसी भी फ़ाइल प्रकार एम्बेड कर सकते हैं कैसे इंटरॉप असेंबलियों के बिना

Question

मैं इस How can I embed any file type into Microsoft Word using OpenXml 2.0

करने के लिए कोशिश कर रहा हूँ, लेकिन केवल OpenXML SDK 2.5 (कोई इंटरॉप असेंबलियों)

मैं अन्य शब्द एम्बेड कर सकते हैं (का उपयोग करते हुए या (पीडीएफ, एमपी 3 कार्यालय) निम्नलिखित कोड नमूना का उपयोग करके फ़ाइलें से here
(हम NuGet और WindowsBase)

से DocumentFormat.OpenXml के लिए एक संदर्भ जोड़ने की जरूरत है, लेकिन मैं मुसीबत यह पुनर्रचना किसी भी फ़ाइल प्रकार स्वीकार करने के लिए हो रही है आदि)

Answer 1

यहां एक कोड है जो अधिकांश प्रकार के लिए काम करेगा, लेकिन केवल विंडोज बॉक्स पर, क्योंकि इसे ओएलई तकनीक की आवश्यकता है। असल में यह अंततः निर्भर करता है कि ओएलई अंतरंगता के कारण आपकी मशीन कैसे कॉन्फ़िगर की गई है, इसलिए आपको इसे थोड़ा सा करने की आवश्यकता है।

// make sure this all is running in an STA thread (for example, mark Main with the STAThread attribute) 

// the file you want to embed 
string embeddedDocumentPath = @"C:\mypath\myfile.txt"; 

// a temp file that will be created, and embedded in the final .docx  
string packagePath = @"C:\Temp\test.bin"; 

// a temp image file that will be created and embedded in the final .docx 
string packageIconPath = @"C:\Temp\test.emf"; 

// package embeddedDocumentPath -> create the two OpenXML embeddings 
Packager.PackageFile(packagePath, packageIconPath, embeddedDocumentPath); 

// create the word doc 
using (var doc = WordprocessingDocument.Create(@"C:\mypath\ContainingDocument.docx", WordprocessingDocumentType.Document)) 
{ 
    var main = doc.AddMainDocumentPart(); 

    // add icon embedding 
    var imagePart = main.AddImagePart(ImagePartType.Emf); 
    imagePart.FeedData(File.OpenRead(packageIconPath)); 

    // add package embedding 
    var objectPart = main.AddEmbeddedObjectPart("application/vnd.openxmlformats-officedocument.oleObject"); 
    objectPart.FeedData(File.OpenRead(packagePath)); 

    // build a sample doc 
    main.Document = BuildDocument(main.GetIdOfPart(imagePart), main.GetIdOfPart(objectPart), "Package"); 
} 

private static Document BuildDocument(string imagePartId, string objPartId, string progId) 
{ 
    var shapeId = "R" + Guid.NewGuid().ToString("N"); // come up with a unique name... 

    var element = 
     new Document(
     new Body(
      new Paragraph(new Run(new Text("This is the containing document."))), 
      new Paragraph(new Run(new Text("This is the embedded document: "))), 
      new Paragraph(
      new Run(
       new EmbeddedObject(
       new v.Shape(
        new v.ImageData 
        { 
         RelationshipId = imagePartId, // rel to image part 
         Title = ""      // this is important! 
        }) 
        { 
         Id = shapeId 
        }, 
       new ovml.OleObject 
       { 
        Type = ovml.OleValues.Embed, 
        DrawAspect = ovml.OleDrawAspectValues.Icon, 
        ProgId = progId, // COM progid 
        Id = objPartId,  // rel to embedded part 
        ShapeId = shapeId, // link to shape 
        ObjectId = "R" + Guid.NewGuid().ToString("N") // come up with a unique name... 
       } 
       ))) 
     ) 
    ); 
    return element; 
} 

और यहाँ उपयोगिता कोड है कि एक पैकेज और एक छवि (ईएमएफ) इनपुट फ़ाइल से फ़ाइल बनाने जाएगा:

यह है कि एक .docx फ़ाइल बनाता है एक नमूना कोड है। अब, पीडीएफ के लिए, यह कोड असफल हो सकता है (जैसे मैंने कहा कि यह निर्भर करता है कि आपने एडोब रीडर इंस्टॉल किया है या नहीं, इसका संस्करण इत्यादि)। क्यों पीडीएफ फाइलों OleCreateFromFile सीधे समर्थन नहीं करते (undercovers

HKEY_CLASSES_ROOT\AcroExch.Document.DC\PackageOnFileDrop 

मुझे यकीन है कि नहीं हूँ, अगर: यदि यह OleCreateFromFile पर विफल रहता है, तो आप को बनाने के लिए/एक रजिस्ट्री कुंजी इस तरह 'PackageOnFileDrop' नाम जोड़ने की कोशिश कर सकते आपने एक्रोबैट रीडर स्थापित किया है, यह सब AcroRd32.exe द्वारा प्रबंधित किया जाता है जो एडोब द्वारा एक COM सर्वर प्रदाता है), मुझे लगता है कि यह एक सुरक्षा सुविधा हो सकती है, और मुझे नहीं पता कि शब्द कैसे इसे रोकता है ...
