Как скачать файл DOCX, созданный с открытым XML SDK?

Document.cs:

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

namespace GeneratedCode
{
    public class GeneratedClass
    {
        // Creates an Document instance and adds its children.
        public Document GenerateDocument()
        {
            Document document1 = new Document(){ MCAttributes = new MarkupCompatibilityAttributes(){ Ignorable = "w14 w15 wp14" }  };
            document1.AddNamespaceDeclaration("wpc", "http://schemas.microsoft.com/office/word/2010/wordprocessingCanvas");
            document1.AddNamespaceDeclaration("mc", "http://schemas.openxmlformats.org/markup-compatibility/2006");
            document1.AddNamespaceDeclaration("o", "urn:schemas-microsoft-com:office:office");
            document1.AddNamespaceDeclaration("r", "http://schemas.openxmlformats.org/officeDocument/2006/relationships");

            document1.AddNamespaceDeclaration("wp", "http://schemas.openxmlformats.org/drawingml/2006/wordprocessingDrawing");
            document1.AddNamespaceDeclaration("w10", "urn:schemas-microsoft-com:office:word");

            Body body1 = new Body();

            Paragraph paragraph1 = new Paragraph(){ RsidParagraphMarkRevision = "00100E91", RsidParagraphAddition = "009D5F75", RsidRunAdditionDefault = "00100E91" };

            ParagraphProperties paragraphProperties1 = new ParagraphProperties();

            ParagraphMarkRunProperties paragraphMarkRunProperties1 = new ParagraphMarkRunProperties();
            Languages languages1 = new Languages(){ Val = "en-US" };

            Text text1 = new Text();
            text1.Text = "Hello";

            run1.Append(runProperties1);
            run1.Append(text1);
            BookmarkStart bookmarkStart1 = new BookmarkStart(){ Name = "_GoBack", Id = "0" };
            BookmarkEnd bookmarkEnd1 = new BookmarkEnd(){ Id = "0" };

            paragraph1.Append(paragraphProperties1);
            paragraph1.Append(run1);
            paragraph1.Append(bookmarkStart1);
            paragraph1.Append(bookmarkEnd1);

            SectionProperties sectionProperties1 = new SectionProperties(){ RsidRPr = "00100E91", RsidR = "009D5F75" };
            PageSize pageSize1 = new PageSize(){ Width = (UInt32Value)11906U, Height = (UInt32Value)16838U };
            PageMargin pageMargin1 = new PageMargin(){ Top = 1134, Right = (UInt32Value)850U, Bottom = 1134, Left = (UInt32Value)1701U, Header = (UInt32Value)708U, Footer = (UInt32Value)708U, Gutter = (UInt32Value)0U };

            body1.Append(sectionProperties1);

            document1.Append(body1);
            return document1;
        }


    }
}

Я хочу получить документ, созданный на этом коде (код из Open XML SDK).

как, нажав кнопку, чтобы подготовить документ (получить hello.docx)?

Созданный проект: asp.net mvc 4 add: 1) Контроллер 2) View-> code:

    @using (Html.BeginForm())
    {
        <input type="submit" value="Get docx file" />
    }

Спасибо вам всем.

Проблема решена.

Метод:

    public ActionResult GetFile()
    {
        try
        {
            byte[] document = new GeneratedClass().CreateDocumenBytes();
            return File(document, "application/vnd.openxmlformats-officedocument.wordprocessingml.document", "Contract.docx");
        }
        catch (Exception ex)
        {
            ViewBag.ErrorMessage = ex.Message;
            throw;
        }
    }

Посмотреть:

    @using (Html.BeginForm())
    {
        @Html.ActionLink("Экспорт договора в Word","GetFile","get")
    }
