    Something like

    private void Button_Click(object sender, EventArgs e)
        {
            Button b = (Button) sender;
            //button name
        }
    

    msdn

    Assume you have button1, button2, button3. You can point all the buttons click event to the same method on the design page:

    or in the load event

    button1.Click+=button_Click;
    button2.Click+=button_Click;
    button3.Click+=button_Click;
    
    and you write the method
    
    private void button_Click(object sender, EventArgs e)
    {
        var button=sender as Button;
        // your code
    
    }

    Subscribe same handler for all buttons and use sender to get button which raised event:

    void Button_Click(object sender, EventArgs e)
    {
        Button button = (Button)sender;
        // use Name or Tag of button
    }
    

    If your buttons named as alphabets A..Z then you can just use button.Name to get letter. If buttons have names like buttonA...buttonZ you can get substring from button.Name to get related letter (or button.Name.Last()). If buttons have names not related to alphabets, then you can use Tag property of button to set and get letter which is assigned to each button.
