❔ Question about getter property of list

so, i have some class containg property of type: List<string> , how can i thread-safe return this list as some kind of snapshot of current state of list? right now i'm doing it in followoing way but i'm not sure if it okey

private readonly object _lock = new();
private readonly List<string> _strings = [];
public IReadOnlyList<string> Strings {
  get {
    lock(_lock)
      return [.._strings];
  }
}

private readonly object _lock = new();
private readonly List<string> _strings = [];
public IReadOnlyList<string> Strings {
  get {
    lock(_lock)
      return [.._strings];
  }
}

a snapshot would be a copy so looks fine at first glance i dunno if i'd make it a property, because copying a list might be expensive in terms of what a property getter should do

do you have any other idea? in theory, i need it for single iteration

make it a method instead

in few places i used yield return inside lock
