調用方法:

LocalSetupHelper.SetData(Sss.維護, "密碼", "123456");  //保存

var c=LocalSetupHelper.GetData(Sss.前臺, "密碼");  獲取

LocalSetupHelper.RemovePropertyName(Sss.前臺, "密碼"); //清除子節點

LocalSetupHelper.RemovePropertyName(Sss.前臺); 清除父節點

enum Sss
{
維護,
前臺,
}

輸出格式:

{
"前臺": {
"密碼": "123456",
},
"維護": {
"密碼": "123456"
}
}

當然也有這種節點的

{
"密碼": "123456",
"密碼xxx": "123456"
}
