我正在开发一个Asp.net core 2.0的Web API项目。我需要一种库或方法来创建Word文档。我已经尝试了NPOI和DocX，但它们都不如预期好用。有人能推荐一个工具吗？

一开始看起来，下面的链接可能有所帮助：

无论如何，关于使用Microsoft的Open XML SDK创建DOCX - Word文档 - 你可以使用版本2.8.1将Open XML SDK安装到你的解决方案中。它是完全免费的。

文档可在以下链接中找到：

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

MSDN上 => https://learn.microsoft.com/en-us/office/open-xml/open-xml-sdk

PS：MSDN文档都是关于SDK 2.5而不是2.8.1的，但正如GIT链接中所解释的那样，没有实质性的变化。

无论如何，在Web APP CORE 2.0中使用它，你可以按照以下步骤进行：

安装Nuget Packages版本SDK 2.8.1；

在你的控制器中引用以下命名空间：

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

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"));
    }
}

并且像这样调用：

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

如果您想要在用户点击链接后从他们的浏览器生成一个docx文件并保存到他们的计算机中，可以执行以下操作：

// 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");
    }

}

上述代码甚至展示了如何使用最重要的对象：body、段落、运行和文本。记得始终遵循这个顺序！
