Explain WindowsPhone Application/Global variable?

Answer 1

We can set a variable that can be accessed on all pages of a Windows Phone App

Step1:

App.xaml.cs

public partial class App : Application
   {
        public string sName { get; set; }
   }

Step2:

Now access application variable "sName" in entire application like this

(App.Current as App).sName = "Test value";//set value                                                               
string myvalue=(App.Current as App).sName;//get value
