I am creating a Piano Application with all the keys as buttons.

It works when i click the Piano button using mouse click.

Now, I want the same event to occur when i press a key in the keyboard.
What event should I use ?

This is the event for the button click

C#

private void button1_Click(object sender, EventArgs e)
        {
            MessageBox.Show("A");
            Beep(349, 150);

        }

Now I want the same process to happen when i click the "A" key in my keyboard.
I know its some event. But I couldn't find it.
How should I proceed to achieve it ? And how should i implement it ?

Thanks in advance

You have form? Create the KeyDown[^] Event.

From http://stackoverflow.com/a/3334956[^]

C#

public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        this.BringToFront();
        this.Focus();
        this.KeyPreview = true;
        this.KeyDown += new KeyEventHandler(Form1_KeyDown);
        
    }

    void Form1_KeyDown(object sender, KeyEventArgs e)
    {
        Console.WriteLine("test");
    }
