NPOI使用NancyFx返回.xls文件

Question

我正在嘗試創建導出功能，在該功能中，我將創建的.xls文件發送給用戶。

我正在使用NancyFx進行請求，並使用NPOI進行excel文件的創建。 無法弄清楚此代碼出了什么問題，我得到了OK 200響應，但沒有內容/文件返回。

public class ExportService
    {
        private HSSFWorkbook HssfWorkbook { get; set; }

        public ExportService()
        {
            HssfWorkbook = new HSSFWorkbook();
        }

        public Response Export()
        {
            string fileName = "test2.xls";

            var response = new Response();

            response.Headers.Add("Content-Disposition", string.Format("attachment;filename={0}", fileName));

            InitializeWorkbook();
            GenerateData();

            response.Contents(WriteToStream());
            return response.AsAttachment(fileName, "application/vnd.ms-exce");
        }

        private MemoryStream WriteToStream()
        {
            //Write the stream data of workbook to the root directory
            MemoryStream file = new MemoryStream();
            HssfWorkbook.Write(file);
            return file;
        }

        private void GenerateData()
        {
            var sheet1 = HssfWorkbook.CreateSheet("Försäljning");

            sheet1.CreateRow(0).CreateCell(0).SetCellValue("Detta är ett test");
            int x = 1;
            for (int i = 1; i <= 15; i++)
            {
                var row = sheet1.CreateRow(i);
                for (int j = 0; j < 15; j++)
                {
                    row.CreateCell(j).SetCellValue(x++);
                }
            }
        }

        private void InitializeWorkbook()
        {
            ////create a entry of DocumentSummaryInformation
            var documentSummaryInformation = PropertySetFactory.CreateDocumentSummaryInformation();

            documentSummaryInformation.Company = "Test Company";

            HssfWorkbook.DocumentSummaryInformation = documentSummaryInformation;

            ////create a entry of SummaryInformation
            var summaryInformation  = PropertySetFactory.CreateSummaryInformation();
            summaryInformation.Subject = "Test Subject";
            HssfWorkbook.SummaryInformation = summaryInformation;
        }
    }

問題是我的請求來自AJAX調用。 需要保存文件，然后將用戶重定向到在我的AJAX響應中創建的文件。
