使用OpenXml将HTML文本内容转换为Word

Question

我有一个富文本框，其中包含html格式的文本，并且我们可以插入复制的图像。 我尝试了AlternativeFormatImportPart和AltChunk方法。 它正在生成文档，但出现以下错误。 请让我知道我在这里想念什么。

 MemoryStream ms;// = new MemoryStream(new UTF8Encoding(true).GetPreamble().Concat(Encoding.UTF8.GetBytes(h)).ToArray()); ms = new MemoryStream(HtmlToWord(fileContent)); //MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(h)); // Create alternative format import part. AlternativeFormatImportPart chunk = mainDocPart.AddAlternativeFormatImportPart( "application/xhtml+xml", altChunkId); chunk.FeedData(ms); AltChunk altChunk = new AltChunk(); altChunk.Id = altChunkId; 

 public static byte[] HtmlToWord(String html) { const string filename = "test.docx"; if (File.Exists(filename)) File.Delete(filename); var doc = new Document(); using (MemoryStream generatedDocument = new MemoryStream()) { using (WordprocessingDocument package = WordprocessingDocument.Create( generatedDocument, WordprocessingDocumentType.Document)) { MainDocumentPart mainPart = package.MainDocumentPart; if (mainPart == null) { mainPart = package.AddMainDocumentPart(); new Document(new Body()).Save(mainPart); } HtmlConverter converter = new HtmlConverter(mainPart); converter.ExcludeLinkAnchor = true; converter.RefreshStyles(); converter.ImageProcessing = ImageProcessing.AutomaticDownload; //converter.BaseImageUrl = new Uri(domainNameURL + "Images/"); converter.ConsiderDivAsParagraph = false; Body body = mainPart.Document.Body; var paragraphs = converter.Parse(html); for (int i = 0; i < paragraphs.Count; i++) { body.Append(paragraphs[i]); } mainPart.Document.Save(); } return generatedDocument.ToArray(); } }

MemoryStream的AlternativeFormatImportPart中存在一些问题，文档的格式设置不正确。 因此，采用了另一种方法，即使用HtmlToWord方法将html内容保存到word中，并使用FileStream读取文件内容并提供AlternativeFormatImportPart。

string docFileName;
HtmlToWord(fileContent, out docFileName);
FileStream fileStream = File.Open(docFileName, FileMode.Open);                
// Create alternative format import part.
AlternativeFormatImportPart chunk =mainDocPart.AddAlternativeFormatImportPart(AlternativeFormatImportPartType.WordprocessingML, altChunkId);
chunk.FeedData(fileStream);
AltChunk altChunk = new AltChunk();
altChunk.Id = altChunkId;
