我如何返回一个OPENXML Word文档的MVC ActionResult

Question

我有在控制台中创建文件的基本代码(见下文)。但我写一个MVC应用程序，所以我需要返回XML文档作为ActionResult....我在网上搜索了2个小时，寻找一个简单的例子，没有运气。

我要添加什么来使它成为ActionResult ?

       string filePath = @"C:tempOpenXMLTest.docx";
        using (WordprocessingDocument doc = WordprocessingDocument.Create(filePath, WordprocessingDocumentType.Document))
        {
            //// Creates the MainDocumentPart and add it to the document (doc)     
            MainDocumentPart mainPart = doc.AddMainDocumentPart();
            mainPart.Document = new Document(
                new Body(
                    new Paragraph(
                        new Run(
                            new Text("Hello World!!!!!")))));
        }

下面是一些示例代码。注意，这段代码不是从磁盘加载文件，而是动态创建文件并写入MemoryStream。写入磁盘所需的更改是最小的。

    public ActionResult DownloadDocx()
    {
        MemoryStream ms;
        using (ms = new MemoryStream())
        {
            using (WordprocessingDocument wordDocument = WordprocessingDocument.Create(ms, WordprocessingDocumentType.Document))
            {
                MainDocumentPart mainPart = wordDocument.AddMainDocumentPart();
                mainPart.Document = new Document(
                    new Body(
                        new Paragraph(
                            new Run(
                                new Text("Hello world!")))));
            }
        }
        return File(ms.ToArray(), "application/vnd.openxmlformats-officedocument.wordprocessingml.document", "Test.docx");
    }
