If the array is synchronized, then yes, ToArray is thread-safe, as shown in Reflector: public override object[] ToArray() { lock (this._root) { return this._list.ToArray(); } } But if not using a synchronized ArrayList, then you might want to explicitly lock the SyncRoot, similar to approach #1. Excellent question. If the array is synchronized, then yes, ToArray is thread-safe, as shown in Reflector:

public override object[] ToArray()
{
lock (this._root)
{
return this._list.ToArray();
}
}
