如何在没有互操作程序集的情况下将任何文件类型嵌入到Microsoft Word中

我正在尝试这样做如何使用OpenXml 2.0将任何文件类型嵌入到Microsoft Word中

但只使用OpenXml SDK 2.5（没有互操作程序集）

我可以使用以下代码示例嵌入其他单词（或办公室）文件
（我们需要从NuGet和WindowsBase添加对DocumentFormat.OpenXml的引用）

但我无法重构它以接受任何文件类型（pdf，mp3等）

using DocumentFormat.OpenXml.Packaging; using DocumentFormat.OpenXml.Wordprocessing; using DocumentFormat.OpenXml; using v = DocumentFormat.OpenXml.Vml; using ovml = DocumentFormat.OpenXml.Vml.Office; using System.IO; class Program { static void Main(string[] args) { //Just update the following 2 variables to point to existng files string containingDocumentPath = @"C:\Temp\Word\ContainingDocument.docx"; string embeddedDocumentPath = @"C:\Temp\Word\EmbeddedDocument.docx"; CreatePackage(containingDocumentPath, embeddedDocumentPath); } private static void CreatePackage(string containingDocumentPath, string embeddedDocumentPath) { using (WordprocessingDocument package = WordprocessingDocument.Create(containingDocumentPath, WordprocessingDocumentType.Document)) { AddParts(package, embeddedDocumentPath); } } private static void AddParts(WordprocessingDocument parent, string embeddedDocumentPath) { var mainDocumentPart = parent.AddMainDocumentPart(); GenerateMainDocumentPart().Save(mainDocumentPart); var embeddedPackagePart = mainDocumentPart.AddNewPart("application/vnd.openxmlformats-" + "officedocument.wordprocessingml.document", "rId1"); GenerateEmbeddedPackagePart(embeddedPackagePart, embeddedDocumentPath); var imagePart = mainDocumentPart.AddNewPart("image/x-emf", "rId2"); GenerateImagePart(imagePart); } private static Document GenerateMainDocumentPart() { var element = new Document( new Body( new Paragraph( new Run( new Text( "This is the containing document."))), new

"_x0000_i1025", Style = "width:76.5pt;height:49.5pt", Ole = TrueFalseBlankValue.FromBoolean(false)//v.BooleanEntryWithBlankValues.Empty }, new ovml.OleObject() { Type = ovml.OleValues.Embed, ProgId = "Word.Document.12", ShapeId = "_x0000_i1025", DrawAspect = ovml.OleDrawAspectValues.Icon, ObjectId = "_1299573545", Id = "rId1" } ) //{ // DxaOriginal = (UInt32Value)1531UL, // DyaOriginal =

will generate an exception if an invalid // filename is passed. using (FileStream fsEmbeddedDocument = File.OpenRead(embeddedDocumentPath)) { embeddedDocumentBytes = new

Answer 1

这是一个适用于大多数类型的代码，但仅适用于Windows机器，因为它需要OLE技术。 事实上，由于OLE的亲密性，它最终取决于你的机器的配置方式，所以你需要尝试一下。

这是一个创建.docx文件的示例代码：

 // 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; } 

这里是实用程序代码，它将从输入文件创建包和图像（EMF）文件。 现在，对于PDF，此代码可能会失败（就像我说的，这取决于您是否安装了Adobe Reader，其版本等）。 如果它在OleCreateFromFile上失败，那么您可以尝试创建/添加名为’PackageOnFileDrop’的注册表项，如下所示：

 HKEY_CLASSES_ROOT\AcroExch.Document.DC\PackageOnFileDrop 

我不确定为什么PDF文件不直接支持OleCreateFromFile （暗装，如果你已经安装了Acrobat Reader，这全部由Adobe的COM服务器提供商AcroRd32.exe处理），我认为它可能是一个安全function，我不知道Word如何规避这个……

 public static class Packager { public static void PackageFile(string outputFile, string outputImageFile, string inputFile) { if (outputFile == null) throw new ArgumentNullException(nameof(outputFile)); if (outputImageFile == null) throw new ArgumentNullException(nameof(outputImageFile)); if (inputFile == null) throw new ArgumentNullException(nameof(inputFile)); IStorage storage; CheckHr(StgCreateStorageEx( outputFile, STGM_CREATE | STGM_READWRITE | STGM_SHARE_EXCLUSIVE, STGFMT_DOCFILE, 0, IntPtr.Zero, IntPtr.Zero, typeof(IStorage).GUID, out storage)); // note 1: if you get 'Use of Ole1 services requiring DDE windows is disabled' error, make sure the executing thread is STA // // note 2: if you want packager to succeed on PDF files instead of reporting 0x8000ffff (E_UNEXPECTED), make sure // there exists a key named "PackageOnFileDrop", like this: HKEY_CLASSES_ROOT\AcroExch.Document.DC\PackageOnFileDrop // IDataObject ps; // from System.Runtime.InteropServices.ComTypes CheckHr(OleCreateFromFile( Guid.Empty, inputFile, typeof(IDataObject).GUID, 0, IntPtr.Zero, IntPtr.Zero, storage, out ps)); var format = new FORMATETC(); format.cfFormat = CF_ENHMETAFILE; format.dwAspect = DVASPECT.DVASPECT_CONTENT; format.lindex = -1; format.tymed = TYMED.TYMED_ENHMF; STGMEDIUM medium; ps.GetData(ref format, out medium); CopyEnhMetaFile(medium.unionmember, outputImageFile); DeleteEnhMetaFile(medium.unionmember); storage.Commit(0); Marshal.FinalReleaseComObject(ps); Marshal.FinalReleaseComObject(storage); } private static void CheckHr(int hr) { if (hr != 0) throw new Win32Exception(hr); } [InterfaceType(ComInterfaceType.InterfaceIsIUnknown), Guid("0000000B-0000-0000-C000-000000000046")] private interface IStorage { void _VtblGap1_6(); // we only need Commit void Commit(int grfCommitFlags); } [DllImport("ole32.dll")] private static extern int StgCreateStorageEx( [MarshalAs(UnmanagedType.LPWStr)] string pwcsName, int grfMode, int stgfmt, int grfAttrs, IntPtr pStgOptions, IntPtr reserved2, [MarshalAs(UnmanagedType.LPStruct)] Guid riid, out IStorage ppObjectOpen); [DllImport("ole32.dll")] private static extern int OleCreateFromFile( [MarshalAs(UnmanagedType.LPStruct)] Guid rclsid, [MarshalAs(UnmanagedType.LPWStr)] string lpszFileName, [MarshalAs(UnmanagedType.LPStruct)] Guid riid, int renderopt, IntPtr lpFormatEtc, IntPtr pClientSite, IStorage pStg, out IDataObject ppStg ); [DllImport("gdi32.dll", SetLastError = true)] private static extern bool DeleteEnhMetaFile(IntPtr hemf); [DllImport("gdi32.dll", CharSet = CharSet.Unicode, SetLastError = true)] private static extern IntPtr CopyEnhMetaFile(IntPtr hemfSrc, string lpszFile); private const int CF_ENHMETAFILE = 14; private const int STGM_READWRITE = 2; private const int STGM_SHARE_EXCLUSIVE = 0x10; private const int STGM_CREATE = 0x1000; private const int STGFMT_DOCFILE = 5; }
