C # ToolStrip make four sides docked floating toolbar

  This article mainly introduces the production of C # ToolStrip floating toolbar, can dock up/down/left/right, the code below

About the production of floating bar   In fact, the code given by Atzie is quite detailed: I mainly give a rewrite of the ToolStrip code snippet, added three ToolStripPanel       code as follows:     public partial class Mytoolstrip:too Lstrip     {        public Mytoolstrip ()         {            InitializeComponent ();             this.
