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
