Save data on local storage - xaml

Question

I am developing an app using Xamarin Forms PCL.
I want to save this class (I use this class as List in code)
public class TagInformation {
[PrimaryKey, AutoIncrement]
public int Id { get; set; }
public string name { get; set; }
public bool isJob { get; set; }
public string _color { get; set; }
[Ignore]
public Color color { get; set; }
[Ignore]
public JobInformation jobInformation { get; set; }
public TagInformation(Color c, string n) {
color = c;
_color = c.ToHex();
name = n;
isJob = false;
}
public TagInformation() {
}
public void setColor() {
color = Color.FromHex(_color);
}
}
public class JobInformation {
public string shopName { get; set; }
public int wage { get; set; }
public bool isHoliday { get; set; }
public int holidayWage { get; set; }
public bool isMid { get; set; }
public int midnightWage { get; set; }
public bool[] holidayFlgs { get; set; }
public DateTime midStart { get; set; }
public DateTime midEnd { get; set; }
public int tranceportCost { get; set; }
public int closeDay { get; set; }
public int payMentDay { get; set; }
public TimeSpan shortRest { get; set; }
public TimeSpan longRest { get; set; }
public TimeSpan shortRestTime { get; set; }
public TimeSpan longRestTime { get; set; }
public TimeSpan commuteTime { get; set; }
public JobInformation() {
/* do samething */
}
}
Using SQLite, this class has another class, so it doesn't work on.
Is there any other way?
Do you have any ideas?

You could try to use Xamarin.Essentials: Preferences to save it as a json string.
1.Install the Newtonsoft.Json nuget.
2.Serialize your class to json string and save it with a key.
TagInformation tarinformation = xxxxx;
string jsonString = JsonConvert.SerializeObject(tarinformation);
Preferences.Set("your_key", jsonString); //save the data
3.Retrieve a value from preferences and deserialize the string.
var myValue = Preferences.Get("my_key", "default_value");//get the data string
TagInformation infor = JsonConvert.DeserializeObject<TagInformation>(myValue); //deserialize to your class
