Question

我正在尝试使用FileResult对象在Excel中的本地磁盘上打开Excel文件。当我单击要打开的文件时，它会下载名为与我的ActionResult（WTF？）相同的文件，然后它会显示＆＃34;选择程序＆＃34;单击下载的文件时窗口。如果我选择Excel，它会打开它，但我缺少什么使它作为excel文件下载并在没有额外步骤的情况下打开它？下面是我打开文件的switch语句。感谢

public ActionResult GetFile(string path)
    {

        string extension = new FileInfo(path).Extension;
        if (extension != null || extension != string.Empty)
        {
            switch (extension)
            {
                case ".pdf":
                    return File(path, "application/pdf");
                case ".txt":
                    return File(path, "application/plain");
                case ".jpeg":
                    return File(path, "application/jpeg");
                case ".doc":
                    return File(path, "application/msword");
                case ".docx":
                    return File(path, "application/msword");
                case ".xls":
                    return File(path, "application/msexcel");
                case ".xlsx":
                    return File(path, "application/msexcel");
                default:
                    return File(path, "application/octet-stream");
            }
        }
        return View("Index");
    }

检查一下：

 case ".xls":
    return File(path, "application/vnd.ms-excel");
 case ".xlsx":
   return File(path, "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");

使用FileResult MVC4下载/打开Excel文件不起作用
