"text": "Saw this place on tv introduced as a place to give people who are deaf or hard of hearing a place to work. Thought it was well meaning and interesting so decided to have a visit. \n\nArrived I think around 11:30am. Walked in and was greeted by no one. The place was pretty much empty except for one table (more people came in later closer to lunch). Didn't quite know how this place operates and no one there to show us, so we picked a table ourself and sat down, waited, but no one came over to give us a menu or anything. \n\nWent over to the cashier and asked. Gave us a sheet where we can tick what we would like to order. The lunch menu you get to pick 3 dishes out of 6 and you get with it a bowl of soup and unlimited refill of rice (the rice is not the plain white ones but with added healthy red grains). This costs $42 per person, and each person MUST order one! I think it must be because they have free rice refills. At the time I wasn't feeling that well so I didn't wan't to eat but was forced (well could have walked out but we came all the from NT to try this place) to buy a lunch set each. I couldn't eat mine and my friend wasn't able to eat 2 sets so it was all wasted. Why do they have to have this rule? \n\nI wasn't able to eat much so the food review is from the friend I went with. The food was bland, a bit like hospital food, so guess that makes it healthy. The ingredients were not good quality, One of the dish was green cabbage but there was yellowing and \"stringy\" in the mouth. \n\nFor a place that promotes healthy eating, it does not show in the quality of their ingredients. And for a place that tries to help the handicapped in society, it's good someone is doing that but they also need to provide the training for the staff to work in this place. Even the manager there, who was not deaf, will do good with a bit of training as we had to walk up to him to ask for everything. \n\nGood intentions, but very disappointed by everything else!",

我想提取opening_hours以使用以下模型构建新的List<OpenCloseDaysModel>：
public class OpenCloseDaysModel
{
public int day { get; set; }
public List<OpenCloseResultModel> range { get; set; }
public bool is_open { get; set; }
}
public class OpenCloseResultModel
{
public string start { get; set; }
public string end { get; set; }
}
我尝试使用以下功能：
public async static Task<string> FormatOpenCloseFromGoogle(GooglePlaceApiOpeningHours GooglePlaceApiOpeningHours)
{
string Output = null;
int CurrentDay = 0;
string start = null;
string end = null;
OpenCloseDaysModel OpenCloseDaysModel = new OpenCloseDaysModel();
List<OpenCloseDaysModel> OpenCloseDaysList = new List<OpenCloseDaysModel>();
List<OpenCloseResultModel> OpenCloseResultModel = new List<OpenCloseResultModel>();
//HttpContext.Current.Response.Write("<hr />" + JsonConvert.SerializeObject(GooglePlaceApiOpeningHours, Formatting.None, new JsonSerializerSettings { NullValueHandling = NullValueHandling.Ignore }) + "</ hr>");
if (GooglePlaceApiOpeningHours != null)
{
foreach (var item in GooglePlaceApiOpeningHours?.periods)
{
TimeSpan tsstart;
TimeSpan tsend;
if (!TimeSpan.TryParse(item.open?.time?.Substring(0, 2) + ":" + item.open?.time?.Substring(2, 2), CultureInfo.InvariantCulture, out tsstart))
{
return null;
}
else
{
start = tsstart.ToString(@"hh\:mm");
}
if (!TimeSpan.TryParse(item.close?.time?.Substring(0, 2) + ":" + item.close?.time?.Substring(2, 2), CultureInfo.InvariantCulture, out tsend))
{
return null;
}
else
{
end = tsend.ToString(@"hh\:mm");
}
OpenCloseDaysModel.day = CurrentDay;
if (item.open.day != CurrentDay)
{
OpenCloseDaysModel.range = OpenCloseResultModel;
OpenCloseDaysList.Add(OpenCloseDaysModel);
OpenCloseDaysModel = new OpenCloseDaysModel();
OpenCloseResultModel = new List<OpenCloseResultModel>();
OpenCloseResultModel.Add(new OpenCloseResultModel { start = start, end = end });
}
else
{
OpenCloseResultModel.Add(new OpenCloseResultModel { start = start, end = end });
}
CurrentDay = item.open.day;
}
OpenCloseDaysModel.day = CurrentDay;
OpenCloseResultModel.Add(new OpenCloseResultModel { start = start, end = end });
OpenCloseDaysModel.range = OpenCloseResultModel;
OpenCloseDaysList.Add(OpenCloseDaysModel);
List<OpenCloseDaysModel> OrderdOpenCloseDaysList = new List<OpenCloseDaysModel>();
for (int i = 1; i < 7; i++)
{
var DayQuery = OpenCloseDaysList.OrderByDescending(o => o.day).Where(o => o.day == i).FirstOrDefault();
if (DayQuery != null)
{
OrderdOpenCloseDaysList.Add(new OpenCloseDaysModel { day = i, range = DayQuery.range, is_open = true });
}
else
{
OrderdOpenCloseDaysList.Add(new OpenCloseDaysModel { day = i, range = null, is_open = false });
}
}
//for sunday
var DayQuerySunday = OpenCloseDaysList.Where(o => o.day == 0).FirstOrDefault();
if (DayQuerySunday != null)
{
OrderdOpenCloseDaysList.Add(new OpenCloseDaysModel { day = 0, range = DayQuerySunday.range, is_open = true });
}
else
{
OrderdOpenCloseDaysList.Add(new OpenCloseDaysModel { day = 0, range = null, is_open = false });
}
Output = JsonConvert.SerializeObject(OrderdOpenCloseDaysList, Formatting.None, new JsonSerializerSettings { NullValueHandling = NullValueHandling.Ignore });
}
return Output;
}
但它返回了一些错误的价值......
有没有更简单的方法来构建我的模型：OpenCloseDaysModel？
答案 0 :(得分：1)
我会使用LINQ方法在模型之间进行转换，然后填写缺失的日期，按日排序结果，最后序列化。也许是这样的：
def summarizeData(filename):
#open the file and read the contents
with open(filename, 'r') as f:
data = f.read().splitlines()
return data
使用您的示例数据，这会得到以下结果（为了便于阅读，我在此处添加了格式，但根据您的原始代码，上述输出未格式化）：
public static string FormatOpenCloseFromGoogle(GooglePlaceApiOpeningHours openingHoursModel)
{
if (openingHoursModel == null || openingHoursModel.periods == null) return null;
// build a list of open days from Google data
var list = openingHoursModel.periods
.GroupBy(p => p.open.day)
.Select(g => new OpenCloseDaysModel
{
day = g.Key,
is_open = true,
range = g.Select(p => new OpenCloseResultModel
{
start = p.open.time.Substring(0, 2) + ":" + p.open.time.Substring(2, 2),
end = p.close != null ? p.close.time.Substring(0, 2) + ":" + p.close.time.Substring(2, 2) : "23:59"
})
.OrderBy(r => r.start)
.ToList()
})
.ToList();
// fill in missing days
for (int i = 0; i < 7; i++)
{
if (!list.Any(m => m.day == i))
list.Add(new OpenCloseDaysModel { day = i, is_open = false, range = null });
}
// sort days with Sunday at the end and return the serialized result
var settings = new JsonSerializerSettings { NullValueHandling = NullValueHandling.Ignore };
return JsonConvert.SerializeObject(list.OrderBy(m => m.day > 0 ? m.day : 7), settings);
}
