Fixed 鸟粪一样的TreeView下的NodeMouseDoubleClick Bug

  private void treeView1_NodeMouseDoubleClick(object sender, TreeNodeMouseClickEventArgs e) {
             Rectangle baseRectangle = this.treeView1.SelectedNode.Bounds;
             Point mouseClickPoint = e.Location;

             if (this.treeView1.SelectedNode == e.Node) {
                 if (WasInBounds(baseRectangle, mouseClickPoint)) {
                     MessageBox.Show(string.Format("the selected node text:{0}", e.Node.Text));
                 }
             }
         }

         /// <summary>
         /// Return a value indicating whether the click point belong the reactangle region.
         /// </summary>
         /// <param name="baseRectangle"></param>
         /// <param name="clickPoint"></param>
         /// <returns></returns>
         private static bool WasInBounds(Rectangle baseRectangle, Point clickPoint) {
             bool result = true;

             int bottom = baseRectangle.Bottom;
             int right = baseRectangle.Right;
             int left = baseRectangle.Left;
             int top = baseRectangle.Top;

             if ((clickPoint.X < left || clickPoint.X > right) || (clickPoint.Y > bottom || clickPoint.Y < top)) {
                 result = false;
             }

             return result;
         }

废话不多说，用过的人看了代码自然明白
