C:编辑/保存/发送docx文档

openxml-sdk docx openxml .net-core c#

Nicolas S. · 技术社区 · 6 年前

被很多问题缠住了。在ASP.NET核心服务器上使用OpenXML,我希望基于模板创建一个新的docx文档。一旦这个文档被完全保存,我希望它被发送到我的客户机,这样他可以直接下载它。这是我的代码:

public IActionResult Post([FromBody] Consultant consultant)
    {
            using (Stream templateStream = new MemoryStream(Properties.Resources.templateDossierTech))
            using (WordprocessingDocument template =
                WordprocessingDocument.Open(templateStream, false))
            {

                string fileName = environment.WebRootPath + @"\Resources\"+ consultant.FirstName + "_" + consultant.LastName + ".docx";
                WordprocessingDocument dossierTechniqueDocument =
                    WordprocessingDocument.Create(fileName,
                        WordprocessingDocumentType.Document);
                foreach (var part in template.Parts)
                {
                    dossierTechniqueDocument.AddPart(part.OpenXmlPart, part.RelationshipId);
                }

                var body = dossierTechniqueDocument.MainDocumentPart.Document.Body;
                var paras = body.Elements();

                foreach (var para in paras)
                {
                    foreach (var run in para.Elements())
                    {
                        foreach (var text in run.Elements())
                        {
                            if (text.InnerText.Contains("{{prenom}}"))
                            {
                                var t = new Text(text.InnerText.Replace("{{prenom}}", consultant.FirstName));
                                run.RemoveAllChildren<Text>();
                                run.AppendChild(t);
                            }

                        }
                    }
                }
                dossierTechniqueDocument.MainDocumentPart.Document.Save();
                dossierTechniqueDocument.Close();
                var cd = new System.Net.Mime.ContentDisposition
                {
                    FileName = consultant.FirstName + "_" + consultant.LastName + ".docx",
                    Inline = true
                };

                Response.Headers.Add("Content-Disposition", cd.ToString());

                Response.Headers.Add("X-Content-Type-Options", "nosniff");
                return File(System.IO.File.ReadAllBytes(fileName),"application/vnd.openxmlformats-officedocument.wordprocessingml.document","Dossier Technique");
        }
    }

乍一看,它似乎保存得很好,但当我试图在Word上打开它时,它说它由于某种原因被损坏了。当我试图发送它时,这也是同样的问题。一旦它被发送,我的客户机就不会下载它(Ajax查询)。你们中有人知道怎么修吗?

以下是从模板创建文档的函数:

static void GenerateDocumentFromTemplate(string inputPath, string outputPath)
    {
        MemoryStream documentStream;
        using (Stream stream = File.OpenRead(inputPath))
        {
            documentStream = new MemoryStream((int)stream.Length);
            CopyStream(stream, documentStream);
            documentStream.Position = 0L;
        }

        using (WordprocessingDocument template = WordprocessingDocument.Open(documentStream, true))
        {
            template.ChangeDocumentType(DocumentFormat.OpenXml.WordprocessingDocumentType.Document);
            MainDocumentPart mainPart = template.MainDocumentPart;
            mainPart.DocumentSettingsPart.AddExternalRelationship("http://schemas.openxmlformats.org/officeDocument/2006/relationships/attachedTemplate",
               new Uri(inputPath, UriKind.Absolute));

            mainPart.Document.Save();
        }


        File.WriteAllBytes(outputPath, documentStream.ToArray());
    }
