Delete file on server

问题:

I have a file path in the format file://SERVERNAME/FOLDER$/FOLDER/image.jpg. I call System.IO.File.Delete(Server.MapPath(file://SERVERNAME/FOLDER$/FOLDER/image.jpg)) to delete the file, but i get the error file:/SERVERNAME/FOLDER$/FOLDER/image.jpg' is not a valid virtual path. I notice that a '/' is missing and I do not know why. How will I delete such file?

I have tried converting my file path to file:////SERVERNAME//FOLDER$//FOLDER//image.jpg but this did not help. Same thing happens. If I omit the Server.MapPath, I get an error saying URI is not supported.

How to do this please?

回答1:

Since you are doing System.IO.File.Delete I assume you have the permission to delete the file; so you can:

var uri = new Uri("file://SERVERNAME/FOLDER$/FOLDER/image.jpg", UriKind.Absolute);
System.IO.File.Delete(uri.LocalPath);

Have you tried

\\SERVERNAME\FOLDER$\FOLDER\image.jpg

make sure the user account running the application has access to remote machine

Given that you have enough permissions to access that file, you need to convert the given path to \\SERVERNAME\FOLDER$\FOLDER\image.jpg
