1,引用 using Newtonsoft.Json.Linq;
2,因为是数组所以用JArray解析,对象可以用JObject
1 if (method == "checkedBox") { 2 string jsonStr = context.Request["nodesJson"]; 3 4 JArray ja = JArray.Parse(jsonStr); 5 Dictionary<string, string> dic = new Dictionary<string, string>(); 6 7 foreach (JToken str in ja) { 8 dic.Add(str["name"].ToString(),str["id"].ToString()); 9 } 10 11 }
附上 zTree 官网 api 和 Newtonsoft.json 文档
