How to use dictionary for Keyboard key and display value?

Try something like this:

private Dictionary dic;

bool changed1 = false;

bool changed2 = false;

public MainWindow()

{

InitializeComponent();

dic = new Dictionary();

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");

}

private string ConvertToSymbols(TextBox tb)

{

var chars = new List();

for (int i = 0; i < tb.Text.Length; i++)

{

if (char.IsDigit(tb.Text[i]))

{

char symbol = dic[tb.Text[i] - 48][0];

chars.Add(symbol);

}

else if (dic.ContainsValue(tb.Text[i].ToString()))

{

chars.Add(tb.Text[i]);

}

return new string(chars.ToArray());

}

private long ConvertFromSymbols(TextBox tb)

{

var chars = new List();

for (int i = 0; i < tb.Text.Length; i++)

{

foreach (int k in dic.Keys)

{

if (tb.Text[i] == dic[k][0])

{

chars.Add((char)(k + 48));

break;

}

string s = new string(chars.ToArray());

return Convert.ToInt64(s);

}

private void textBox1_TextChanged(object sender, TextChangedEventArgs e)

{

if (changed1)

{

textBox1.CaretIndex = textBox1.Text.Length + 1;

changed1 = false;

return;

}

changed1 = true;

textBox1.Text = ConvertToSymbols(textBox1);

}

private void textBox2_TextChanged(object sender, TextChangedEventArgs e)

{

if (changed2)

{

textBox2.CaretIndex = textBox2.Text.Length + 1;

changed2 = false;

return;

}

if (textBox2.Text.Length == 0) return;

changed2 = true;

textBox2.Text = ConvertToSymbols(textBox2);

}

private void btnAdd_Click(object sender, RoutedEventArgs e)

{

if (textBox1.Text.Length == 0)

{

MessageBox.Show("First TextBox is still empty");

textBox1.Focus();

return;

}

if (textBox2.Text.Length == 0)

{

MessageBox.Show("Second TextBox is still empty");

textBox2.Focus();

return;

}

long l1 = ConvertFromSymbols(textBox1);

long l2 = ConvertFromSymbols(textBox2);

txtTotal.Text = (l1 + l2).ToString();

txtTotal.Text = ConvertToSymbols(txtTotal);

}
