WeifenLuo.WinFormsUI.Docking 自动保存界面布局！

    private DeserializeDockContent m_deserializeDockContent = new DeserializeDockContent(GetContentFromPersistString);
        /// <summary>
        /// 配置委托函数
         /// </summary>
        /// <param name="persistString"></param>
        /// <returns></returns>
        private static IDockContent GetContentFromPersistString(string persistString)
        {
            if (persistString == typeof(TreeViewForm).ToString())
            {
                return _treeViewForm;
            }
            else if (persistString == typeof(TimeWindowViewForm).ToString())
            {
                return _timeWindowViewForm;
            }
            else if (persistString == typeof(StartPageForm).ToString())
                return _startPageForm;
            else if (persistString == typeof(MapViewForm).ToString())
                return _mapViewForm;
            else if (persistString == typeof(DetailViewForm).ToString())
                return _detailViewForm;
            else
            {
                return null;
            }
        }

然后在主界面的Load事件中加上如下代码：
   string configFile = Path.Combine(Properties.Settings.Default.TempPath, "DockPanel.config");
   if (File.Exists(configFile))
    {
       dpnMain.LoadFromXml(configFile, m_deserializeDockContent);
    }

在Close事件中加上保存即可，代码如下：
  string configFile = Path.Combine(Properties.Settings.Default.TempPath, "DockPanel.config");
  dpnMain.SaveAsXml(configFile);
