c# - 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。我需要一个库或创建 Word 文档的方法。我搜索了一个尝试过的 NPOI 和 DocX。两者都没有预期的那么好。谁能给我推荐一个工具？

乍一看，以下链接可以提供帮助:

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。都是免费的。

文档位于:

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

在 MSDN 上 => https://learn.microsoft.com/en-us/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，但是正如 GIT 链接中所解释的那样，没有实质性的变化。

无论如何，要在 Web APP CORE 2.0 中使用它，您可以执行以下操作:

1. 安装 Nuget Packgaes 版本 SDK 2.8.1

2. 在您的 Controller 中引用以下命名空间:

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

3. 如果您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"));
       }
   }
   

并这样调用它:

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

1. 如果您想要生成一个 docx 并从用户的浏览器保存到用户的计算机中，请在点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");
       }
   
   }
