ConcurrentDictionary 有什么办法确保一次添加多项的原子性吗?

[bthulu]

    private readonly ConcurrentDictionary<int, string> Dict = new();

    // 如何保证原子性?
    public void AddMore(IEnumerable<(int, string)> items)
    {
        foreach ((int key, string? value) in items)
        {
            Dict.TryAdd(key, value);
        }
    }

没有办法。换个常规字典自己 lock 吧。
