Cuture.Extensions.SystemTextJson.Dynamic

Extension of System.Text.Json to support dynamic access using dynamic

System.Text.Json 的拓展,以支持使用 dynamic 进行动态访问

  • 使用 dynamic 访问,无需预定义实体类型
  • 支持修改/添加属性

创建 JSON 对象

Json字符串 创建 JSON 对象

using System.Text.Json.Dynamic;

var rawJson = 
    """
    {
    "a":1,
    "b":2.0,
    "c":{
        "a":"1",
        "b":"2",
        },
    }
    """;

var json = JSON.parse(rawJson);

对象 创建 JSON 对象

using System.Text.Json.Dynamic;

var json = JSON.create(new object());

访问 JSON 对象

//访问属性
var a = json.a;
var c = json.a.b.c;

//访问数组
var v2 = json.x[1];

//访问属性并转换为基础数据类型
bool b1 = json.b;
string s1 = json.s;

//局部反序列化
MyClass obj = json.a.b; //将 json.a.b 反序列化到类型 MyClass

//获取内部的原始 System.Text.Json.Nodes.* 对象
JsonArray array = json.ArrayProperty;
JsonObject obj = json.ObjectProperty;
JsonNode node = json.NodeProperty;

修改 JSON 对象

//设置值(不可多级设置未定义字段)
json.a = new {};
json.a.b = 1;

json.c = new
{
    d = new
    {
        e = 2
    }
};

int value = json.a.b;

检查 JSON 对象

//判断是否为未定义字段
var b1 = json.notexistfield == null;
var b2 = json.notexistfield == JSON.Undefined;
var b3 = JSON.isUndefined(json.notexistfield);

//多级属性判断是否为未定义字段
var b4 = JSON.isUndefined(() => json.a.b.c.e.f.g.h.i.j.k);

IEnumerable

使用IEnumerable以支持使用Linq, (C#不支持实现dynamic的接口,所以需要额外的转换)

//遍历Array
//显式赋值类型
IEnumerable<dynamic> enumerable = json.Array;
//通过IDynamicEnumerable
var enumerable = ((IDynamicEnumerable)json.Array).AsEnumerable();

//遍历属性
//显式赋值类型
IEnumerable<KeyValuePair<string, dynamic?>> enumerable = json;
//通过IDynamicKeyValueEnumerable
var enumerable = ((IDynamicKeyValueEnumerable)json).AsEnumerable();

Index && Range

支持使用 Index 和 Range 语法访问数组

Note: 当前使用 Range 语法将会创建新的对象,对其修改不会反映到原始对象

//Index
var value = json.Array[^1];

//Range
var items = json.Array[..1];
