如何在ASP MVC中下载由NPOI生成的xls文件

我找到了如何将Excel电子表格流回客户端但在aspx代码中的例子。 代码如下

using (var exportData = new MemoryStream()) { workbook.Write(exportData); string saveAsFileName = string.Format("MembershipExport-{0:d}.xls", DateTime.Now).Replace("/", "-"); Response.ContentType = "application/vnd.ms-excel"; Response.AddHeader("Content-Disposition", string.Format("attachment;filename={0}", saveAsFileName)); Response.Clear(); Response.BinaryWrite(exportData.GetBuffer()); Response.End(); } 

我正在使用asp MVC 5和webApi Controller。 我想将此代码迁移到返回HttpResponseMessage的WebApiController。 有什么好主意吗？

这会有帮助吗？

 public FileResult DownloadFile() { // code to create workbook using (var exportData = new MemoryStream()) { workbook.Write(exportData); string saveAsFileName = string.Format("MembershipExport-{0:d}.xls", DateTime.Now).Replace("/", "-"); byte[] bytes = exportData.ToArray(); return File(bytes, "application/vnd.ms-excel", saveAsFileName); } }
