check the considered file is not locked and privilege to work with it.

C#

[PermissionSet(SecurityAction.LinkDemand, Name = "FullTrust")]
private static void SetFileToHidden(string filePath)
{
    var attrs = File.GetAttributes(filePath);
    File.SetAttributes(filePath, attrs | FileAttributes.Hidden);
}
