Read File

string strOperatingFileName = "OperateZone.json";
string _strJson = ReadStringFromFile(strOperatingFileName);

public string ReadStringFromFile(string filename)
{
    string path = PathForDocumentsFile(filename);

    if (File.Exists(path))
    {
        FileStream file = new FileStream(path, FileMode.Open, FileAccess.Read);
        StreamReader sr = new StreamReader(file);

        string str = null;
        str = sr.ReadToEnd();

        sr.Close();
        file.Close();

        return str;
    }

    else
    {
        return null;
    }
}


public string PathForDocumentsFile(string filename)
{
    if (Application.platform == RuntimePlatform.IPhonePlayer)
    {
        string path = Application.dataPath.Substring(0, Application.dataPath.Length - 5);
        path = path.Substring(0, path.LastIndexOf('/'));
        return Path.Combine(Path.Combine(path, "Documents"), filename);
    }
    else if (Application.platform == RuntimePlatform.Android)
    {
        string path = Application.persistentDataPath;
        path = path.Substring(0, path.LastIndexOf('/'));
        return Path.Combine(path, filename);
    }
    else
    {
        string path = Application.dataPath;
        path = path.Substring(0, path.LastIndexOf('/'));
        return Path.Combine(path, filename);
    }
}

Write File

string strJson = JsonFx.Json.JsonWriter.Serialize(opZoneSetting);
WriteStringToFile(strJson, strOperatingFileName);

public void WriteStringToFile(string str, string filename)
{
    string path = PathForDocumentsFile(filename);
    FileInfo fileInfo = new FileInfo(path);

    if (Application.platform == RuntimePlatform.Android || Application.platform == RuntimePlatform.IPhonePlayer)
    {
        if (fileInfo.Exists)
        {
            return;
        }
        else
        {
            FileStream file = new FileStream(path, FileMode.Create, FileAccess.Write);
            StreamWriter sw = new StreamWriter(file);
            sw.WriteLine(str);

            sw.Close();
            file.Close();
        }
    }
    else
    {
        FileStream file = new FileStream(path, FileMode.Create, FileAccess.Write);
        StreamWriter sw = new StreamWriter(file);
        sw.WriteLine(str);

        sw.Close();
        file.Close();
    }
}
