C # - How to remove the Maximize, Minimize, but keep a Close button only?

I created a graphic component and wrote a command line that removed the control bar from the graphic component, but all the buttons disappeared. Is there any way to just leave the Close button?

Or will I have that Form component type for another?

public Form1()
{
     InitializeComponent();
     this.StartPosition = FormStartPosition.CenterScreen;
     this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;                
}
