2) Items 루프 돌면서 비교 제어(for)
               for (int i = 0; i < contextMenuStripAction.Items.Count; i++)
                {
                    String text = contextMenuStripAction.Items[i].Text;
                   
                    contextMenuStripAction.Items[i].Enabled = false;
                }


3) Items 루프 돌면서 비교 제어(foreach)
                foreach (ToolStripItem c in contextMenuStripAction.Items)
                {
                    if (c is ToolStripMenuItem)
                    {
                        ToolStripMenuItem t = new ToolStripMenuItem();
                        t = (ToolStripMenuItem)c;
                        t.Enabled = false;
                    }
