            dic.Add(6, "P");
            dic.Add(7, "*");
            dic.Add(8, "@");
            dic.Add(9, "Q");

The examples at www.dotnetpears.com are console apps. That's right.
Your question was about "How to use dictionary".
In a WPF application dictionaries can be used the same way than in a console app.

C#

public partial class Window1 : Window
    {
        public Window1()
        {
            InitializeComponent();
            dic.Add(1, "E");
            dic.Add(2, "G");
            dic.Add(3, "$");
            dic.Add(4, "/");
            dic.Add(5, "!");
            dic.Add(6, "P");
            dic.Add(7, "*");
            dic.Add(8, "@");
            dic.Add(9, "Q");
            dic.Add(0, "U");
        }
        public static Dictionary<int, string> dic = new Dictionary<int, string>();

        private void txt_TextChanged(object sender, TextChangedEventArgs e)
        {
            txtval.Text = "";
            char[] str = txt.Text.ToArray();
            foreach (char items in str)
            {
                var cx = (from t in dic where t.Key == Convert.ToInt32(items.ToString()) select t);
                foreach (var item in cx)
                {
                    txtval.Text += item.Value;

                }
            }
            //dic.Select(t => t.Key == Convert.ToInt32(txt.Text)).Select(t => t).ToString(); //dic.Select(t => t.Key == Convert.ToInt32(txt.Text));
        }
    }
