.net Json 扁平化处理

利用JsonDocument 及递归 实现简易的Json扁平化处理

using System.Text.Json;
var str = "{\"Code\":200,\"Data\":{\"url1\":\"1111\",\"url2\":\"2222\",\"url3\":\"3333\",\"url4\":\"4444\"}}";
//扁平化数据结果
var data = new Dictionary<string, string>();
//用来记录json属性名
var pathStack = new Stack<string>();
//数据层级分割字符串
var splitChar = ".";
//转换为JsonDocument对象
using (var doc = JsonDocument.Parse(str))
{JsonFlatten(doc.RootElement);
}//递归实现json节点解析=>扁平化
void JsonFlatten(JsonElement element)
{Action<dynamic> recordAction = (name) => pathStack.Push((pathStack.Count > 0 ? (pathStack.Peek() + splitChar) : string.Empty) + name);foreach (JsonProperty property in element.EnumerateObject()){recordAction(property.Name);switch (property.Value.ValueKind){case JsonValueKind.Object:JsonFlatten(property.Value);break;case JsonValueKind.Array:int index = 0;foreach (JsonElement arrayElement in property.Value.EnumerateArray()){recordAction(index.ToString());JsonFlatten(arrayElement);pathStack.Pop();index++;}break;default:string key = pathStack.Peek();data[key] = property.Value.ToString();break ;}pathStack.Pop();}
}
