Lack of Assembly Reference C#

Question

I have an error of lack of use of Directive or a Assembly Reference aimed atKeyCodand Modifiers

Can anyone tell me what it would be and how I can carry it ?

    private void lblAutoCod_MouseClick(object sender, MouseEventArgs e)
    {
        if (e.KeyCode == Keys.C && e.Modifiers == Keys.Control)
        {

            MessageBox.Show("You pressed ctrl + c");
        }
    }

The purpose is to make who in a click on a label the text is copied.

You are confusing the event. The correct is KeyEventArgs. Not MouseEventArgs. Your code makes no sense.

If the goal is to test which button mouse was pressed, change the event to:

private void lblAutoCod_MouseClick(object sender, MouseEventArgs e)
{
    if (e.Button == MouseButtons.Right)
    {
        MessageBox.Show("Botão direito do mouse pressionado.");
    }
}
