C# Bei Enter in Textbox Button Klick ausführen

Im Designer der Form-Klasse:

this.textBox_Search.KeyDown += new System.Windows.Forms.KeyEventHandler(this.TextBox_Search_KeyDown);

In der Klasse selber:

private void TextBox_Search_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyCode == Keys.Enter)
            {
                Button_Search_Click(sender, e);
            }
        }
