C# Making it so the Enter Key behaves as if a button has been pressed

Question

How do I code it so that when the enter key has been pressed it behaves as if a button on the existing form has been pressed?

Let's say the button on the form makes it so a display message of hello shows up

 private void buttonHello_Click(object sender, EventArgs e)
{
    MessageBox.Show("Hello");
}

How do I make it so when the enter key is pressed it does the same thing (for the life of me I can't remember and it's probably really simple and I'm being really dumb)

Answer 1

WinForms? If yes, select the FORM. Now in the Properties Pane (bottom right of the screen by default) change the AcceptButton property to "buttonHello".

See Form.AcceptButton:

Gets or sets the button on the form that is clicked when the user presses the ENTER key.

Here's what it looks like in the Properties Pane:

Answer 2

Capture the Enter key down event, like this:

private void Form1_KeyDown(object sender, KeyEventArgs e) 
{
    if (e.KeyCode == Keys.Enter){
        button.PerformClick();
    }
}

Answer 3

In your Form properties, set AcceptButton = yourButton, That's it.

Answer 4

add a Key Down event handler to your form. Then check if the enter key has been pressed

private void form_KeyDown(object sender, KeyEventArgs e)
{
    if(e.KeyCode == Keys.Enter)
        buttonHello.PerformClick();
}
