无法以编程方式重命名目录

Question

I have asp.net web forms project. It is created as "WebSite" and is running on my local iis. In this project I've created folder with subfolder, where some picutes are stored.(~/listings/listing1, ~/listings/listing2...)

I can programmatically add new files to this subfolders, can delete this subfolders, but I can't rename them. I've tried to rename this subfolders manually: when project is not runing - I am able to do so, when i run debuging in Visual Studio, I can't rename them even manually.

For programmatical renaming I am using this code: DirectoryInfo rootDir = new DirectoryInfo(oldListingFolderPath);
rootDir.MoveTo(newListingFolderPath); This cause error "Access to the path ... is denied." I've granted full controll to this folder for NETWORK SERVICES, IIS_IUSERS, USER. I've also tried to remove readonly attributes for files/folders in subfolder that should be renamed, but this didn't help.

Are there any other ways to rename needed subfolder. Or can you suggest any ways to find, what is blocking renaming of the folder.

EDIT1: paths of subfolders (~/listings/listing1) are mentioned just for example. When I am renaming directory, I am using full path to file: Server.MapPath("~/listings/listing1"). Sorry for not mentioning this before.

EDIT2: I've tried to do this in other way: firs I am creating new folder with needed new name, then I am copying existing folder to new folder and then I am deleting old folder. This works. But I still can't just rename existing folder...

Answer 1

The problem seems to be that when the ASP.NET web application executes, it still has a reference to(which means ASP.NET runtime is still using) the folder. Hence the access violation error.

Solution is to move the folder from ~ folder to elsewhere in the filesystem, not inside ~ .

~/listings/listing1, ~/listings/listing2 - is a virtual path. To work with files you need to work with physical path.

Add PhysicalApplicationPath to directory path

string dir_path = HttpContext.Current.Request.PhysicalApplicationPath + "listings\listing1\";

or Server.MapPath("/") or HttpRuntime.AppDomainAppVirtualPath - depends on the type of application
