c# ConfigurationManager

1.读取  

ConfigurationManager.AppSettings.Get("Name")

2.添加

  自定义文件

Configuration c = ConfigurationManager.OpenExeConfiguration(AppDomain.CurrentDomain.BaseDirectory + "app.config");AppSettingsSection s = c.GetSection("appSettings") as AppSettingsSection;s.Settings.Add("Name", "Irelia");c.SaveAs(AppDomain.CurrentDomain.BaseDirectory + "app.config");

 

默认文件(*.exe.config)

Configuration c = ConfigurationManager.OpenExeConfiguration( ConfigurationUserLevel.None);AppSettingsSection s = c.GetSection("appSettings") as AppSettingsSection;s.Settings.Add("Name", "Irelia");c.Save();

（注意，试过了，不能自定义section的，将appSetting改成其他节点的名字无法识别，同时，appSetting要添加到最后的节点，要不然读取报错)
