【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

| addValue | Single | 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
| path | String | 节点路径 |
| newValue | Object | 即将变成的值 |
| newValueType | NodeTypeEnum | 即将变成值的类型 |
NodeContentChangeBeforeFromJson
节点内容改变之前（通过JSON解释）
| path | String | 节点路径 |
| json | String | 即将变成的值的JSON字符串 |
NodeContentChangeLater
节点内容改变之后
| path | String | 节点路径 |
| newValue | Object | 变成的值 |
| newValueType | NodeTypeEnum | 变成值的类型 |
