Unity内置JsonUtility.FromJson解析List

 注意：

JsonUtility.FromJson 方法只能接受 json 对象，如果是 json 数组会提示错误 JSON must represent an object type

被转换的对象必须是可被序列化的，需要标记 [System.Serializable] 属性

 

写数据类

public class VideoData { public List<JsonVideoData> datas; } [Serializable] public class JsonVideoData { public int id; public int type; public string name; }

 调用

public List<JsonVideoData> jsonVideoDatas = new List<JsonVideoData>(); void ReadVideoJson() { string jsonStr = File.ReadAllText(videoPathDir + videoJsonName); //Debug.Log(jsonStr); jsonVideoDatas = JsonUtility.FromJson<VideoData>(jsonStr).datas; }

 Json数据，注意json的键和自定义的类的字段完全一致，否则读不到数据

{ "datas": [ { "id": 1, "type": 1, "name": "中国功夫.mp4" }, { "id": 2, "type": 1, "name": "FuChouZhe.mp4" }, { "id": 3, "type": 2, "name": "geminiman30fps.mp4" }, { "id": 4, "type": 2, "name": "JindDianLuoYan3D.mp4" } ] }
