终于弄明白啦怎么用CONFIG文件,在LOAD FORM 时为用户建个CONFIG文件.不是APP.CONFIG.
在关闭窗口时把更改的信息储存在CONFIG文件中.
 protected override  void OnLoad(EventArgs e)
        {            Configuration config;
            base.OnLoad(e);
            ExeConfigurationFileMap filemap = new ExeConfigurationFileMap();
            string FileName;
            string Path = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData);//get the Path of the Config data
            FileName = Path + @"\" +Application.ProductName +@"\ConfigTab.config"; // define the Config data with "Projectname".config
            filemap.ExeConfigFilename = FileName; // call the config data
            config = ConfigurationManager.OpenMappedExeConfiguration(filemap, ConfigurationUserLevel.None);
            try                                  // try to do open the configdata and return a config object
            {
                config = ConfigurationManager.OpenMappedExeConfiguration(filemap, ConfigurationUserLevel.None);
            }
            catch
            {
                MessageBox.Show("Fehler");
               
            }
            KeyValueConfigurationElement mainFormW = config.AppSettings.Settings["MainFormW"];//call the key 
            if (mainFormW == null)                                                  // if don't find, add the key and value.
            {
                mainFormW = new KeyValueConfigurationElement("mainFormW", this.splitContainer1.SplitterDistance.ToString());
                config.AppSettings.Settings.Add(mainFormW);
            }
            else
            {
                this.splitContainer1.SplitterDistance = Convert.ToInt32(mainFormW.Value);
            }
        }
                     // save the configdata before closing
        protected  override void OnFormClosing( FormClosingEventArgs e)
        {
            base.OnFormClosing(e);
           string fileName = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData) + @"\" + Application.ProductName + @"\configtab.config";
           ExeConfigurationFileMap filemap = new ExeConfigurationFileMap();
           filemap.ExeConfigFilename = fileName;
           Configuration config = ConfigurationManager.OpenMappedExeConfiguration(filemap, ConfigurationUserLevel.None);
           KeyValueConfigurationElement mainformw = config.AppSettings.Settings["MainFormW"];
           mainformw.Value = this.splitContainer1.SplitterDistance.ToString();
           config.Save();
        }
    }
不过上边的提示消息仍然有.
