创建docx word文档Web API .NET Core 2.0

Question

我正在Asp.net core 2.0中开发一个Web API项目。我需要一种库或创建Word文档的方法。我搜索了尝试过的NPOI和DocX。两者都不如预期。谁能推荐我一个工具？

乍一看，以下链接可以提供某种帮助：

https://asp.net-hacker.rocks/2017/02/23/word-document-formatter-in-aspnetcore.html

无论如何，关于DOCX-Microsoft使用Open XML SDK的Word文档-您可以使用2.8.1版将Open XML SDK安装到您的解决方案中。全部免费。

可在以下位置获得文档：

在GIT => https://github.com/OfficeDev/Open-XML-SDK上 ;

在MSDN上=> https://docs.microsoft.com/zh-cn/office/open-xml/open-xml-sdk

ps：MSDN文档都是关于版本SDK 2.5而不是2.8.1的，但是如GIT链接中所述，没有实质性的更改。

无论如何在Web APP CORE 2.0中使用它，都可以执行以下操作：

1. 安装Nuget Packgaes版本SDK 2.8.1

2. 在控制器中引用以下名称空间：

   using DocumentFormat.OpenXml;
   using DocumentFormat.OpenXml.Packaging;
   using DocumentFormat.OpenXml.Wordprocessing;
   

3. 如果只想将其保存在本地文件夹中，请执行以下操作：

   public static void CreateWordprocessingDocument(string filepath)
   {
       // Create a document by supplying the filepath. 
       using (WordprocessingDocument wordDocument =
           WordprocessingDocument.Create(filepath, WordprocessingDocumentType.Document))
       {
           // Add a main document part. 
           MainDocumentPart mainPart = wordDocument.AddMainDocumentPart();
   
           // Create the document structure and add some text.
           mainPart.Document = new Document();
           Body body = mainPart.Document.AppendChild(new Body());
           Paragraph para = body.AppendChild(new Paragraph());
           Run run = para.AppendChild(new Run());
           run.AppendChild(new Text("Create text in body - CreateWordprocessingDocument"));
       }
   }
   

并这样称呼：

 public IActionResult GenerateDocx()
    {
        string filePath = @"c:\word\Invoice.docx";
        CreateWordprocessingDocument(filePath);
    }

4. 如果要生成要从其浏览器保存到用户计算机的docx，请在单击链接后执行以下操作：

   // GET verb
   public IActionResult GenerateDocxBrowser()
   {
   
       // open xml sdk - docx
       using (MemoryStream mem = new MemoryStream())
       {
           using (WordprocessingDocument wordDoc = WordprocessingDocument.Create(mem, DocumentFormat.OpenXml.WordprocessingDocumentType.Document, true))
           {
               wordDoc.AddMainDocumentPart();
               // siga a ordem
               Document doc = new Document();
               Body body = new Body();
   
               // 1 paragrafo
               Paragraph para = new Paragraph();
   
               ParagraphProperties paragraphProperties1 = new ParagraphProperties();
               ParagraphStyleId paragraphStyleId1 = new ParagraphStyleId() { Val = "Normal" };
               Justification justification1 = new Justification() { Val = JustificationValues.Center };
               ParagraphMarkRunProperties paragraphMarkRunProperties1 = new ParagraphMarkRunProperties();
   
               paragraphProperties1.Append(paragraphStyleId1);
               paragraphProperties1.Append(justification1);
               paragraphProperties1.Append(paragraphMarkRunProperties1);
   
               Run run = new Run();
               RunProperties runProperties1 = new RunProperties();
   
               Text text = new Text() { Text = "The OpenXML SDK rocks!" };
   
               // siga a ordem 
               run.Append(runProperties1);
               run.Append(text);
               para.Append(paragraphProperties1);
               para.Append(run);
   
               // 2 paragrafo
               Paragraph para2 = new Paragraph();
   
               ParagraphProperties paragraphProperties2 = new ParagraphProperties();
               ParagraphStyleId paragraphStyleId2 = new ParagraphStyleId() { Val = "Normal" };
               Justification justification2 = new Justification() { Val = JustificationValues.Start };
               ParagraphMarkRunProperties paragraphMarkRunProperties2 = new ParagraphMarkRunProperties();
   
               paragraphProperties2.Append(paragraphStyleId2);
               paragraphProperties2.Append(justification2);
               paragraphProperties2.Append(paragraphMarkRunProperties2);
   
               Run run2 = new Run();
               RunProperties runProperties3 = new RunProperties();
               Text text2 = new Text();
               text2.Text = "Teste aqui";
   
               run2.AppendChild(new Break());
               run2.AppendChild(new Text("Hello"));
               run2.AppendChild(new Break());
               run2.AppendChild(new Text("world"));
   
               para2.Append(paragraphProperties2);
               para2.Append(run2);
   
               // todos os 2 paragrafos no main body
               body.Append(para);
               body.Append(para2);
   
               doc.Append(body);
   
               wordDoc.MainDocumentPart.Document = doc;
   
               wordDoc.Close();
           }
           return File(mem.ToArray(), "application/vnd.openxmlformats-officedocument.wordprocessingml.document", "ABC.docx");
       }
   
   }
   

上面的代码甚至显示了如何使用最重要的对象：正文，段落，运行和文本。请记住始终遵循此顺序！
