Question

Answer 1

Something like this should work.

public static class ApplicationState 
{ 
    private static Dictionary _values =
               new Dictionary();

    public static void SetValue(string key, object value) 
    {
        _values.Add(key, value);
    }

    public static T GetValue(string key) 
    {
        return (T)_values[key];
    }
}
