c#怎么解析不确定个数不确定名称的json？如下这种格式，我想把里面的多个日期key对应的数组全取出来转换成list<T>

Question

我看了一下就2层，如果这个是固定的话，那么先循环外层，每一层再算 里面的个数 StringBuilder sb = new StringBuilder();    
                string str = "[{ID:'1',Name:'John',Other:[{Age:'21',Sex:'0'}]},{ID:'2',Name:'Good',Other:[{Age:'36',Sex:'1'}]}]";    
                JavaScriptArray javascript = (JavaScriptArray)JavaScriptConvert.DeserializeObject(str);    
    
                for (int i = 0; i < javascript.Count; i++ )    
                {    
                    JavaScriptObject obj = (JavaScriptObject)javascript[i];    
                    sb.Append("ID：" + obj["ID"].ToString());    
                    sb.Append("Name：" + obj["Name"].ToString());    
                    JavaScriptArray json = (JavaScriptArray)obj["Other"];    
    
                    for (int j = 0; j < json.Count; j++){    
                        JavaScriptObject jsonobj = (JavaScriptObject)json[j];    
                        sb.Append("Age：" + jsonobj["Age"].ToString());    
                        sb.Append("Sex：" + jsonobj["Sex"].ToString());    
                    }    
                }    注意：新版的Newtonsoft.Json的 JavaScriptArray 换成JObect了
上面给的给规则的，不规则一样用

Answer 1

外层的时间key不规则 个数也不固定 

Answer 2

个数不固定不要紧，规则得固定，要不循环也没办法，只能手动一个个根据Key（通过下标）来找Value了不过我看你发的上面的字符串 ，外层还是很标准的.应该没特殊情况吧

Answer 3

 JObject obj = JObject.Parse("");
                foreach (KeyValuePair<string,JToken> item in obj)
                {
                    string key = item.Key;
                    JArray value = (JArray)item.Value;
                }

Answer 4

JObject.Parse里面的参数就是你的json

Answer 5

Dictionary<DateTime,List<SomeClass>>你用这个去反序列化

Answer 6

Dictionary<DateTime,List<T>> dic;//
var list = (from d in dic
                let l = d
                from t in l
                select t).ToList();

Answer 7

from d in dic.Values

Answer 8

给大家一个测试后的代码：static void Main(string[] args)
        {
            var path = "../../json.txt";
            var jsonString = System.IO.File.ReadAllText(path);
            Console.WriteLine(jsonString);            var jsonObj = JObject.Parse(jsonString) as JObject;
            Console.WriteLine(jsonObj);            ProcessJObject( jsonObj);            // 遍历所有的属性
            var enumerator = jsonObj.GetEnumerator();
            while (enumerator.MoveNext())
            {
                var current = enumerator.Current;
                if (current.Value is JArray)
                {
                    var array = current.Value as JArray;
                    for (int i = 0; i < array.Count; i++)
                    {
                        var item = array[i] as JObject;
                        ProcessJObject( item);
                    }
                }
            }        }static void ProcessJObject(JObject target)
        {
            var enumerator = target.GetEnumerator();
            while (enumerator.MoveNext())
            {
                var current = enumerator.Current;
                Console.WriteLine(current.Key);
                Console.WriteLine(current.Value);
            }
        }
