Wpf replacement in code place numericUpDown?

Question

WPF

if (numericUpDown1.Value == 10 && numericUpDown2.Value != 10)
                textBox2.Text = ToN(textBox1.Text, numericUpDown2.Value.ToString());
            else if (numericUpDown2.Value == 10 && numericUpDown1.Value != 10)
                textBox2.Text = FromN(textBox1.Text, numericUpDown1.Value.ToString());
            else if (numericUpDown2.Value != 10 && numericUpDown1.Value != 10)
                textBox2.Text = FromTo(textBox1.Text, numericUpDown1.Value.ToString(), numericUpDown2.Value.ToString());

As in C # there was numericUpDown, then it was used, but it is not in WPF, so they took the usual textBox, how to replace numericUpDown and put textBox.
