json.net，如何从相对路径或实际 json 对象反序列化 json 对象

Question

can someone tell me how to deserialize a json object using either a path to another json file or a json object?

I am trying to make a game where its entirely constructed of config files.

basically I would take either these two...

{
    "LevelConfig" : {
        "SkillGain" : 0.01,
        "MagicGain" : 0.01,
        "XpScale"   : 50.0,
        "HpScale"   : 0.01,
        "MpScale"   : 0.01
    }
}

or 

{
    "LevelConfig" : "../Level.level" (only returns json object if file exists else it tries to return string)
}

and convert them into these

public class JLevel
{
    public float SkillGain { get; set; }
    public float MagicGain { get; set; }
    public float XpScale   { get; set; }
    public float HpScale   { get; set; }
    public float MpScale   { get; set; }
}

public class JEntity
{
        public string Name { get; set; }
        public int    Hp   { get; set; }
        public int    Mp   { get; set; }
        public int    Xp   { get; set; }

        public JLevel   LevelConfig   { get; set; }
        public JColor   ColorConfig   { get; set; }
        public JPhysics PhysicsConfig { get; set; }
}

class Entity
{
        public Entity Load(string filename)
        {
                return ???;
        }
        public void Save(string filename)
        {
                ???;
        }
}

now I know I can just use JsonConvert.DeserializeObject() but that doesn't check for json paths.

Answer 1

First you need to create a class for this Json Object

The name of class should be the same as Object name in JSON

{
    "LevelConfig" : {
        "SkillGain" : 0.01,
        "MagicGain" : 0.01,
        "XpScale"   : 50.0,
        "HpScale"   : 0.01,
        "MpScale"   : 0.01
    }
}



public class LevelConfig
    {
        public double SkillGain { get; set; }
        public double MagicGain { get; set; }
        public double XpScale { get; set; }
        public double HpScale { get; set; }
        public double MpScale { get; set; }
    }

    public class Example
    {
        public LevelConfig LevelConfig { get; set; }
    }

then you need to desalinize it using Newtonsoft

JsonConvert.DeserializeObject<Example>(Json);

Json should be a string. If its an Object the you need to use this on

JsonConvert.DeserializeObject<Example>(JsonConvert.SerializeObject(Json));

Answer 2

class Program
{
    public static void Main()
    {
        var str = "{ LevelConfig : \"level.json\"}";
        var levelConfigs = JsonConvert.DeserializeObject<LevelConfigs>(str);
        var fileTxt = GetFileText(levelConfigs.LevelConfig);
        JLevel level = JsonConvert.DeserializeObject<JLevel>(fileTxt);
        Console.WriteLine(level.HpScale);
        Console.ReadLine();

    }

    private static string GetFileText(string jsonFile)
    {
        return File.ReadAllText(jsonFile);
    }
}

public class LevelConfigs
{
    public string LevelConfig { get; set; }
}

public class JLevel
{
    public float SkillGain { get; set; }
    public float MagicGain { get; set; }
    public float XpScale { get; set; }
    public float HpScale { get; set; }
    public float MpScale { get; set; }
}

public class JEntity
{
    public string Name { get; set; }
    public int Hp { get; set; }
    public int Mp { get; set; }
    public int Xp { get; set; }

    public JLevel LevelConfig { get; set; }

}

you can change your implementation of GetFileText for your needs
