MVC应用程序在IIS Express中工作正常，但在本地IIS Web服务器中不工作

Question

I have created a web application to open a file (Whatever like notepad, excel, PDF, etc.) in local directory. File is opening when running it in IIS Express but in IIS local Web server, it's not opening the file.

I have the files inside the project in Visual studio.

System.IO.DirectoryInfo dir = new System.IO.DirectoryInfo(@"D:// Path ");

IEnumerable<System.IO.FileInfo> fileList = dir.GetFiles("*.*");
var newestFile =
    (from file in fileList
    //where file.Contains(para)
    orderby file.CreationTime
    where file.FullName.Contains(para)
    select new { file.FullName, file.CreationTime })
    .Last();

Process.Start(newestFile.FullName);

return "";

Answer 1

Try creating a virtual directory with path D:// Path. Try giving proper permissions to the folder.

Answer 2

Give proper permission to IISUser for the folder in which you are storing the files.

Hope this would help.

Answer 3

听起来可能是用户权限，请检查为D：//路径设置了哪些安全权限，以及它们与您的有效权限有何不同。
