# 词典节点

Dynamo 2.0 带有各种词典节点供我们使用。这包括 *创建、操作和查询* 节点。

!

#### 创建

1. `Dictionary.ByKeysValues` 会使用提供的值和键创建词典。*（条目数将是最短列表输入内容）*

#### 操作

2. `Dictionary.Components` 会生成输入词典的组件。*（这与创建节点相反。）*
3. `Dictionary.RemoveKeys` 会生成一个新的词典对象，其中输入键已删除。
4. `Dictionary.SetValueAtKeys` 会根据输入键和值生成新词典，以替换相应键处的当前值。
5. `Dictionary.ValueAtKey` 会返回输入键处的值。

#### 查询

6. `Dictionary.Count` 会告诉您词典中有多少键值对。
7. `Dictionary.Keys` 会返回当前存储在词典中的键。
8. `Dictionary.Values` 会返回当前存储在词典中的值。

与词典建立整体关联数据是对使用索引和列表的旧方法的重大替代。
