【vb.net】轻量JSON序列及反序列化

这个代码写的有点时间了，可能有点小bug，欢迎评论区反馈

作用是将Json文本转化成一个HarryNode类进行相关的Json对象处理或者读取，也可以将一个HarryNode对象用ToString变为Json文本。

举例：

1、读取节点数据

dim harryNode = New HarryNode("", "{""msg"":""hello world!""}")
msgbox(harryNode.GetAtt("msg")) '弹窗显示hello world!
 
 
'下面展示更复杂的嵌套读取
dim harryNode = New HarryNode("", "{""node1"": {""msg"":""hello world!""}}")
msgbox(harryNode.GetAtt("node1.msg")) '弹窗显示hello world! 没错，用“.”作为路径连接符进行寻址
 
'如果json的键里包含“.”可以将源码里的“.”替换成其它字符，也可以这样进行取值
msgbox(harryNode.GetAtt("node1")("msg").value
'这里的harryNode.GetAtt("node1")返回的是一个字典对象（String, HarryNode）

2、创建新Json节点，写入数据并输出文本

Dim harryNode = New HarryNode("", "{}")
harryNode.SetAtt("msg", """hello world!""")
MsgBox(harryNode.ToString)
 
'可以看到SetAtt方法的第二个参数输入的字符串需要是json字符串格式，因此字符串本身需要加双引号
'下面可以用SetAtt的另一种重载方法，与上面代码的结果相同
harryNode.SetAtt("msg", "hello world!", NodeTypeEnum.isString)
MsgBox(harryNode.ToString)
 
'同样，对嵌套的复杂json对象，可以如下
harryNode.SetAtt("node1.msg", "hello world!", NodeTypeEnum.isString)
'下面这样写也是可以的
harryNode.SetAtt("node1", "{""msg"": ""hello world!""}")

文档

1、方法和函数

New

构造函数

GetAtt

获得指定路径的VB.NET对象

SetAtt

根据指定路径设置节点值

ReName

重命名某个节点

ToJson

返回JSON字符串，与ToString()等价

GetNode

获得指定路径的HarryNode对象

AddNode

添加子节点

Del

删除指定路径的节点

Merge

合并两个字典节点；

GetChildPath

返回一个当前节点子节点名的列表

Add

指定某个节点的数据加一个值

ConAdd

指定某个节点的数据加一个值，但是限制了数的范围

Mul

指定某个节点的数据乘一个值

Power

指定某个节点的数据求次幂

2、属性

Value

当前节点的VB.NET类型值

3、事件

NodeContentChangeBefore

节点内容改变之前

NodeContentChangeBeforeFromJson

节点内容改变之前（通过JSON解释）

NodeContentChangeLater

节点内容改变之后

NodeContentChangeLaterFromJson

节点内容改变之后（通过JSON解释）
