将文件返回到ASP.NET MVC中的“查看/下载”

public ActionResult Download(){    var document = ...    var cd = new System.Net.Mime.ContentDisposition    {        // for example foo.bak        FileName = document.FileName,        // always prompt the user for downloading, set to true if you want         // the browser to try to show the file inline        Inline = false,     };    Response.AppendHeader("Content-Disposition", cd.ToString());    return File(document.Data, document.ContentType);}

注意： 上面的此示例代码无法正确考虑文件名中的国际字符。有关相关的标准化，请参阅RFC6266。我相信ASP.Net
MVC的
