WP7 Development App/Page wide variable

Does anyone know how to set a variable that ca开发者_C百科n be accessed on all pages of a Windows Phone 7 App?

Without knowing any more specifics of your situation, you could create the variables as members of your App class:

  public partial class App : Application
  {
    ...
    public int foo { get; set; }
    ...
  }

Then access if from wherever:

  (App.Current as App).foo = 3;

Setup global variables, quick and easy, make a new class for GlobalVariables:

public static class GlobalVariables
{
   public static string my_string = "";
   public static int my_int = -1;
}

Then you access the Global Variables class like this:

GlobalVariables.variable_name;

I had the same problem with some variables, I solved it initializing the variables in the constructor of the page and not in any method:

    Dictionary<string, int> clients;//Global variable

    // Constructor
    public MainPage()
    {
        InitializeComponent();
        clients = new Dictionary<string, int>();
    }
