调用方法:
LocalSetupHelper.SetData(Sss.维护, "密码", "123456");//保存<br>
var c=LocalSetupHelper.GetData(Sss.前台, "密码");获取<br><br>LocalSetupHelper.RemovePropertyName(Sss.前台, "密码"); //清除子节点<br><br>LocalSetupHelper.RemovePropertyName(Sss.前台); 清除父节点<br><br><br> enum Sss
{
维护,
前台,
}
输出格式:
{
"前台": {
"密码": "123456",
},
"维护": {
"密码": "123456"
}
}
当然也有这种节点的
{
"密码": "123456",
"密码xxx": "123456"
}

当然这个没仔细看 可能有错误 也没测 自己改改 或者评论区留言 我改
