I am trying to save the state of some labels on an Xamarin.Forms App. I am following the steps of Creating Mobile Apps with Xamarin.Forms book, it shows how to store value per value but recommends this for when you have several info:
An application with many more items might want to consolidate them in a class named AppSettings (for example), serialize that class to an XML or a JSON string, and then save the string in the dictionary.
I am lost about how to do it, I created a simple class
class AppSettings
{
public double? gain = null;
public string mainTitle = "my title";
}
In my constructor I recover the properties in this way
//! Recover appSettings if some
IDictionary<string, object> properties = Application.Current.Properties;
if (properties.ContainsKey("mainTitle"))
{
mainTitle.Text = properties["mainTitle"] as string;
}
//! New code for loading previous keypad text.
App app = Application.Current as App;
mainTitle.Text = app.MainTitle;
And the event that I use to save it is:
void onHomeOptionButtonClicked(object sender, EventArgs args)
{
Button buttonClicked = (Button)sender;
mainTitle.Text = buttonClicked.Text;
// !Save keypad text.
App app = Application.Current as App;
app.MainTitle = mainTitle.Text;
}
What I do not know is how to structure my Class so it can be serialized to JSON (I also do not know how to do this serialization)
I wanted to create a class in C# with this Javascript's idea:
myAppSettings = {
HomePage : {
name1 : "value1",
name2 : "value2"
name3 : {
name3.name1 : "value3.1"
}
},
OtherPage:{
name1 : "value1",
name2 : "value2"
},
.
.
.
};
Which is the correct way to do it in C#?
