我正在使用 FilePathResult 像这样：

return new FilePathResult(path, "text/xml");

我的路径是我们网络上其他地方的路径。这会导致服务器错误。当我检查服务器上的事件日志时，我可以看到这个错误条目：

TransmitFile failed. File Name: \\our\path\to\the\file\filename.dfxp, HRESULT: 0x80070005

同时，事件查看器中也会记录一个警告：

我运行应用程序的服务帐户对文件夹位置具有读取权限。我在 ASP.NET MVC 世界的其他地方没有发现这个问题，所以我想我会在这里问。

It may be too early to tell, however, it seems as though changing from a FilePathResult to a FileContentResult has fixed the problem.

var fileBytes = System.IO.File.ReadAllBytes(fileInfo.FullName);
return new FileContentResult(fileBytes, "text/xml")

I'm not sure what FilePathResult ends up doing internally, but, reading the file with ReadAllBytes seems to avoid the issue.
