如何在Unity中进行JSON解析?

How to do JSON parsing in Unity?

我有一个字符串变量,其中包含以下 JSON。

[
    {
        "MeterLookup_TblRefID": 233,
        "NetworkLookup_TblRefID": 3,
        "Network_Name": "SS-43 SEWA SCADA (Command Center)",
        "Longitude": 55.403544,
        "Latitude": 25.366666,
        "OnOFfStatus": true
    },
    {
        "MeterLookup_TblRefID": 297,
        "NetworkLookup_TblRefID": 4,
        "Network_Name": "SS-8 MaySaloon",
        "Longitude": 55.406274,
        "Latitude": 25.360654,
        "OnOFfStatus": true
    },
    {
        "MeterLookup_TblRefID": 298,
        "NetworkLookup_TblRefID": 5,
        "Network_Name": "SS-1 Al Nasserya Driving School",
        "Longitude": 55.404669,
        "Latitude": 25.367591,
        "OnOFfStatus": true
    }
]   

I want to parse it to a JSON object in unity

。任何人都可以告诉我怎么做。

您可以使用 Unity 的 JSONUtility.

此示例取自 Unity 的文档本身。

using UnityEngine;

[System.Serializable]
public class PlayerInfo
{
    public string name;
    public int lives;
    public float health;

    public static PlayerInfo CreateFromJSON(string jsonString)
    {
        return JsonUtility.FromJson<PlayerInfo>(jsonString);
    }

    // Given JSON input:
    // {"name":"Dr Charles","lives":3,"health":0.8}
    // this example will return a PlayerInfo object with
    // name == "Dr Charles", lives == 3, and health == 0.8f.
}

参考:https://docs.unity3d.com/ScriptReference/JsonUtility.FromJson.html

使用这个函数:

public static T[] DeserializeFromJsonArray<T>(string jsonString)
    {        
            string newJson = "{ \"array\": " + jsonString + "}";
            Wrapper<T> wrapper = JsonUtility.FromJson<Wrapper<T>>(newJson);
            return wrapper.array;        
    }

像这样:

JsonObjectModel[] arrayOfObjects = DeserializeFromJsonArray<JsonObjectModel>(jsonArrayString);

如果您想再次序列化,请使用:

public static string SerializeToJsonArray<T>(T[] arrayToSerialize)
    {
        Wrapper<T> wrapper = new Wrapper<T>();
        wrapper.array = arrayToSerialize;
        return JsonUtility.ToJson(wrapper);
    }

并像这样使用它:

 string jsonString = JsonManager.SerializeToJson<JsonArrayModel>(jsonArrayModel);

如果您有更多问题,我得到了一些 UnityUtils 的回购协议,其中包含此 JsonManaging 的示例:https://github.com/EricBatlle/SimpleUnityUtils/tree/master/Assets/Simple_JsonManager
