Question

This is my class file which contains variables which I need to store.

public class general
{
    String imagename2;
    String name;
    public string getimage()
    {
        return imagename2;
    }

    public void viewimage(String imagename){
        imagename2 = imagename;
    }
}

I firstly store it to the class file

selected = lbFiles.SelectedItem.ToString();
general item = new general();
item.viewimage(selected);
MessageBox.Show(selected);
NavigationService.Navigate(new Uri("/View.xaml", UriKind.Relative));

And by the time it redirect to another page, when I retrieve, its null instead of the value

public View()
{
    InitializeComponent();
    general general = new general(); 
    viewimagename = general.getimage(); // NULL HERE!!!!!!!!!!!!!!!!!!!!!

    this.ReadFromIsolatedStorage(viewimagename+".jpg");
   // LoadFromLocalStorage();
}

I’ve been thinking and not sure why it became null.

Answer 1

You are creating a new instance of the general class each time, hence you get a new, shiny, blank set of field values.
