使用settings.settings来保存数据库配置等信息的。但是设置为“应用程序”级别，就没法方便的用 Properties.Settings.Default.Save() 更改保存。且没法在程序不重启的情况下应用修改后的配置。如果设置为“用户”级别，就存在配置信息保存到appData文件夹下被清空缓存失效的风险。因此回过头来选择ini来保存这些配置信息

读取：

IniFileHelperiniFileHelper=newIniFileHelper(); StringBuildersb=newStringBuilder(60); iniFileHelper.GetIniString("tokeninfo","apiUrl","",sb,sb.Capacity); stringaaa=sb.ToString();

写入：

IniFileHelperiniFileHelper=newIniFileHelper(); iniFileHelper.WriteIniString("tokeninfo","apiUrl","newString");
