c# - How to modify file access control in .NET Core

Question

I'm trying to change the permissions of a file in .NET Core. However, it seems that FileInfo doesn't have any SetAccessControl anymore.

// Create a new FileInfo object.
FileInfo fInfo = new FileInfo(FileName);

// Get a FileSecurity object that represents the 
// current security settings.
FileSecurity fSecurity = fInfo.GetAccessControl();

// Add the FileSystemAccessRule to the security settings. 
fSecurity.AddAccessRule(new FileSystemAccessRule(Account,
                                                Rights,
                                                ControlType));

// Set the new access settings.
fInfo.SetAccessControl(fSecurity);

The goal is just to add execution right to the current owner of a file (which is not Windows or Unix specific feature).

Any clues on how to do that on .NET Core ?

Answer 1

The FileSecurity class is now part of the System.IO.FileSystem.AccessControl package for .NET Core. There is no longer a File.GetAccessControl method so you will need to instantiate the FileSecurity instance yourself.
