How to intercept saved button from textBox1?

Question

C++ / C#

I have a pressed button recorded in textBox1, after clicking on button3, I want to listen to the pressed button that is in textBox1, but since textBox1 accepts string type variables, I had to translate the pressed key into string
That's what I'm talking about

if (Keys.A <= e.KeyCode && e.KeyCode <= Keys.Z)
            {//Character keys
                textBox1.Text = e.KeyCode.ToString();
            }

I could duplicate

if (Keys.A <= e.KeyCode && e.KeyCode <= Keys.Z)
в метод button3_KeyUp

but i need the key the user saved in textBox1
