Question

I get this error anytime I try to upload a file in my ASP.NET MVC application. Can anyone help me out. The error thrown is a System.UnauthorizedAccessException

Access to the path
‘C:\inetpub\wwwroot\IBGTxalert\TxAlert\TxAlert.Web\Files\linqtoexcel.xlsx’
is denied.

Answer 1

You need to set file access permission to Network Service account.

1. In Windows Explorer, locate and select the required folder(ie: C:\inetpub\wwwroot\IBGTxalert\TxAlert\TxAlert.Web\Files).
2. Right-click the folder, and then click Properties.
3. In the Properties dialog box, click the Security tab.
4. On the Security tab, examine the list of users. If the Network
   Service account is not listed, add it.
5. In the Properties dialog box, click the Network Service user name,
   and in the Permissions for NETWORK SERVICE section, select the Read,
   Write, and Modify permissions. Click Apply, and then click OK.
