如何返回OPENXML Word文檔的MVC ActionResult？

Question

我有基本的代碼，在控制檯中創建文件（見下文）..但我正在寫一個MVC應用程序，所以我需要返回該XML文件作爲ActionResult ....我一直在尋找網絡2小時尋找一個簡單的例子，沒有運氣..

什麼我添加到這使它成爲一個ActionResult？

 string filePath = @"C:\temp\OpenXMLTest.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!!!!!"))))); 
     }

下面是一些示例代碼。請注意，此代碼不會從磁盤加載文件，它會即時創建文件並寫入MemoryStream。寫入磁盤所需的更改很少。

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"); 
    }
