Question

Access network folder and files from .NET Core application in IIS

Juan A. Reyes Paulino 20

Greetings, I have an application deployed in IIS with .NET Core 7 and SQL Server, I want to access a network path, write and read files within a folder in the path (\path\folder)

What steps should I follow to achieve this?

Do you mean you want to access the network share inside asp.net core backend? Normally, we will set the IIS's application pool identity to network share ,then this asp.net core application could directly access it by using system.io's file access method.

I understand, I have a Server 1 that has the .NET application in IIS and on Server 2 there is a folder with the files that I want to access when trying to access the path \0.0.0.0\Folder\ from the application it gives me this message "The system cannot find the path specified." So when I put the path in the file explorer it opens the folder without any problem.

server1 need to use the unc path. on server2 share the folder. then the unc path would be:

\\<server2 name><share name>

if the app pool account is a domain admin (not recommended) then you could use the drive share name (c$, d$, etc).

Firstly,you need make sure your current server could access the fileshare inside the network, then you could use below codes to access it, besides, you also need make sure your application pool identity is the network service or domain account which could access that fileshare.

string destinationFile = @"\\filesharename\xxxxxxx";

A start would be to ask a new Question, rather than piggybacking on an old thread. Also, make it clear in your question if you want to make the access from the dotnet code or from SQL Server or somewhere else.

You use the System.IO namespace

https://learn.microsoft.com/en-us/dotnet/api/system.io?view=net-8.0

to access the file share the app pool will need to be a domain account with permissions to the share.
