I am currently setting some strings via this method:
string marketlabel = allmarketdata.#return.markets.COLXPM.label.ToString();
I would like to set the market label dynamically by having a string for the actual market choice.
string currentMarketSelected= this.marketTextBox.Text; // Specific market: COLXPM
string marketlabel=allmarketdata.#return.markets.currentMarketSelected.label.ToString();
I have been searching for a few hours and probably am not explaining correctly. I tried some stuff with reflections with no success. Basically what I want to do is have a textbox or list which contains all the market names and based on which one is selected start setting the data.
Above is the best type of example of what I want to do even though it is not syntactically possible to use a variable in place.
public class Markets
{
public COLXPM COLXPM { get; set; }
//Lots of markets below here
}
public class COLXPM
{
public string marketid { get; set; }
public string label { get; set; }
public string lasttradeprice { get; set; }
public string volume { get; set; }
public string lasttradetime { get; set; }
public string primaryname { get; set; }
public string primarycode { get; set; }
public string secondaryname { get; set; }
public string secondarycode { get; set; }
public List<Recenttrade> recenttrades { get; set; }
public List<Sellorder> sellorders { get; set; }
public List<Buyorder> buyorders { get; set; }
}
public class Return
{
public Markets markets { get; set; }
}
public class RootObject
{
public int success { get; set; }
public Return #return { get; set; }
}
The proposed solution below that worked
string currentMarketSelected = "DOGEBTC"; // Just selecting one of the markets to test it works
var property = allmarketdata.#return.markets.GetType().GetProperty(currentMarketSelected);
dynamic market = property.GetMethod.Invoke(allmarketdata.#return.markets, null);
string marketlabel = market.label.ToString(); //Gets all my selected market data
Here is a solution using reflection.
string currentMarketSelected= this.marketTextBox.Text; // Specific market: COLXPM
var property = allmarketdata.#return.markets.GetType().GetProperty(currentMarketSelected);
dynamic market = property.GetGetMethod().Invoke(allmarketdata.#return.markets, null);
string marketlabel=market.label.ToString();
You need something like this:
public class Markets
{
public COLXPM this[string key]
{
get
{
COLXPM colxpm;
switch (key)
{
// TODO : use "key" to select instance of COLXPM;
case "example1":
colxpm = ...;
break;
default:
throw new NotSupportedException();
}
return colxpm;
}
}
}
Then you can do something like:
string marketlabel=allmarketdata.#return.markets[currentMarketSelected]label.ToString();
This is an indexed property.

I have a Model that is filled with 20 Properties, for instance such as
public class SensorModel
{
public string Trigger1 { get; set; }
public string PathDoor1 { get; set; }
public string PathDoor2 { get; set; }
public string PathTrigger1 { get; set; }
public string PathTrigger2 { get; set; }
public string PathTrigger3 { get; set; }
public string PathTrigger4 { get; set; }
public string PathTrigger5 { get; set; }
public string PathTrigger6 { get; set; }
public string PathTrigger7 { get; set; }
public string PathTrigger8 { get; set; }
}
After declaring and setting their properties by doing such,
SensorModel sensorsData = new SensorModel();
How can I access sensorsData's properties using a loop?
Because I would like to logs all the data into a txt along with DateTime, I find manually accessing is a waste of time.
Is there any way to automate, for instance, using a loop and accessing it one by one?
You can use reflection to achieve your goal:
var model = new SensorModel() {
PathDoor1 = "Foo",
PathDoor2 = "Foo2",
PathTrigger1 = "Value of PT1",
PathTrigger2 = "Value of PT2",
};
foreach(var value in model.GetTriggerValues()) {
Console.WriteLine(value);
}
public class SensorModel
{
public string Trigger1 { get; set; }
public string PathDoor1 { get; set; }
public string PathDoor2 { get; set; }
public string PathTrigger1 { get; set; }
public string PathTrigger2 { get; set; }
/* ... */
public IEnumerable<string> GetTriggerValues() {
foreach(var prop in this.GetType().GetProperties().Where(x => x.Name.StartsWith("PathTrigger"))) {
yield return (string)prop.GetValue(this, null);
}
}
}
This example filters your properties by name, if you want or need a different result set, amend or remove the where clause.
You can use reflection to achieve this:
var obj = new SensorModel();
// ...
// Get all the properties of your class
var props = typeof(SensorModel).GetProperties();
foreach (var prop in props)
{
// Get the "Get" method and invoke it
var propValue = prop.GetGetMethod()?.Invoke(obj, null);
// Do something with the value
Console.Out.WriteLine("propValue = {0}", propValue);
}
I have two objects (A,B) of same class type (PPLWebOperatorGridList). I need update the A.OldValue with B.Value.
I have tried by adding the guid property and update it in the constructor as shown below. But these object list may repeat same value:
public PPLWebOperatorGridList()
{
this.guid = this.FieldName+this.TagName+
this.Length+this.Encoder+this.Value;
}
public string guid { get; set; }
I have tried as below. I know there are bugs in it but consider the idea in it.
private List<PPLWebOperatorGridList> UpddateOldValues(List<PPLWebOperatorGridList> customeTlvList, List<PPLWebOperatorGridList> customeTlvList2)
{
foreach (var list in customeTlvList)
{
foreach (var list1 in customeTlvList2)
{
if (list.guid == list1.guid)
{
list.OldValue = list1.Value;
if (list.children.Count > 0)
UpddateOldValues(list.children.ToList(), list1.children.ToList());
}
}
}
return customeTlvList;
}
The guid property may be same for some in the list.
class PPLWebOperatorGridList
{
public bool expanded { get; set; }
public string FieldName { get; set; }
public string TagName { get; set; }
public string Length { get; set; }
public string Encoder { get; set; }
public string Value { get; set; }
public List<PPLWebOperatorGridList> children { get; set; }
public string OldValue { get; set; }
}
I need to loop through based on index and update the A.OldValue with B.Value. I am not very familiar with linq, so please suggest a solution.
Code without AutoMapper:
List<CountryDM> countryDMList = _countryRepo.GetCountry();
List<CountryVM> countryVMList = new List<CountryVM>();
foreach (CountryDM countryDM in countryDMList)
{
countryVMList.Add(CountryVM.ToViewModel(countryDM));
}
return countryVMList;
I used AutoMapper for the above task. But it returns a NULL list. Please refer the below code:
List<CountryDM> countryDMList = _countryRepo.GetCountry();
Mapper.CreateMap<List<CountryDM>, List<CountryVM>>();
List<CountryVM> countryVMList = new List<CountryVM>();
return Mapper.Map<List<CountryVM>>(countryDMList);
public class CountryDM
{
public int ID { get; set; }
public string CountryCode { get; set; }
public string Description { get; set; }
}
public class CountryVM
{
public int ID { get; set; }
public string CountryCode { get; set; }
public string Description { get; set; }
}
You don't need to define a mapping between lists, just between objects, AutoMapper will know how to extrapolate that:
Mapper.CreateMap<CountryDM, CountryVM>();
the rest stays the same
I want to bind the Json data to the repeater I know only one process that is converting the Json data to data table and then binding data but here I am receiving multilevel json data i do't know how to convert them to data table
input json data:
{"apiAvailableBuses":
[{"droppingPoints":null,"availableSeats":40,"partialCancellationAllowed":false,"arrivalTime":"01:00 AM","cancellationPolicy":"[{\"cutoffTime\":\"1\",\"refundInPercentage\":\"10\"},{\"cutoffTime\":\"2\",\"refundInPercentage\":\"50\"},{\"cutoffTime\":\"4\",\"refundInPercentage\":\"90\"}]","boardingPoints":[{"time":"07:40PM","location":"K.P.H.B,Beside R.S Brothers","id":"2238"}],"operatorName":"Apple I Bus","departureTime":"8:00 PM","mTicketAllowed":false,"idProofRequired":false,"serviceId":"6686","fare":"1000","busType":"Hi-Tech A/c","routeScheduleId":"6686","commPCT":9.0,"operatorId":203,"inventoryType":0},
{
"droppingPoints":null,"availableSeats":41,"partialCancellationAllowed":false,"arrivalTime":"06:00 AM","cancellationPolicy":"[{\"cutoffTime\":\"1\",\"refundInPercentage\":\"10\"},{\"cutoffTime\":\"2\",\"refundInPercentage\":\"50\"},{\"cutoffTime\":\"4\",\"refundInPercentage\":\"90\"}]","boardingPoints":[{"time":"08:00PM","location":"Punjagutta,","id":"2241"}],"operatorName":"Royalcoach Travels","departureTime":"8:00 PM","mTicketAllowed":false,"idProofRequired":false,"serviceId":"6736","fare":"800","busType":"VOLVO","routeScheduleId":"6736","commPCT":9.0,"operatorId":243,"inventoryType":0}
I am trying to convert it to data table by
public void getavailablebuses()
{
string url = string.Format(HttpContext.Current.Server.MapPath("files/getavailablebuses.json"));
using (WebClient client = new WebClient())
{
string json = client.DownloadString(url);
var result = JsonConvert.DeserializeObject<RootObject>(json);
string mm = JObject.Parse(json).SelectToken("apiAvailableBuses").ToString();
// var boardingpoint = JObject.Parse(mm).SelectToken("boardingPoints").ToString();
var Availablebuses = JObject.Parse(json).SelectToken("apiAvailableBuses").ToString();
DataTable dt = (DataTable)JsonConvert.DeserializeObject(Availablebuses, (typeof(DataTable)));
}
public class apiresult
{
public string message { get; set; }
public string success { get; set; }
}
public class RootObject
{
public apiresult apiStatus;
public List<apiAvailableBuses> apiAvailableBuses{ get; set; }
// public string apiAvailableBuses { get; set; }
}
public class apiAvailableBuses
{
public string serviceId { get; set; }
public string fare { get; set; }
public string busType { get; set; }
public string departureTime { get; set; }
public string operatorName { get; set; }
public string cancellationPolicy { get; set; }
public List<boardingpoints> boardingpoints { get; set; }
public string droppingPoints { get; set; }
public string inventoryType { get; set; }
public string routeScheduleId { get; set; }
public int availableSeats { get; set; }
public string arrivalTime { get; set; }
public Boolean idProofRequired { get; set; }
public Boolean partialCancellationAllowed { get; set; }
public int operatorId { get; set; }
public double commPCT { get; set; }
public string mTicketAllowed { get; set; }
}
public class boardingpoints
{
public string location { get; set; }
public string id { get; set; }
public string time { get; set; }
}
public class cancellationPolicy
{
public string cutoffTime { get; set; }
public string refundInPercentage { get; set; }
}
Here in the data table I am unable to get the boarding points, dropping points and cancellation policy
if I load cancellation policy as list or JObject I am getting error
so here I am loading cancellation policy as string.
but I am unable to load boarding points and dropping points.
Please help with this I am scratching my head from two days. Thanks in advance
"I know only one method to bind data to a repeater i.e data table." So this is a perfect opportunity to learn other ways, wouldn't you say?
Why don't you work with the result of JsonConvert.DeserializeObject<RootObject>(json);? This is a RootObject that has a property called apiAvailableBuses which seems to be exactly what you need to bind to your repeater, no?
By the way, a bit of code review:
apiresult and apiAvailableBuses violate Microsoft's rules WRT class names: those should be in PascalCase. Same for the properties of apiresult, e.g. message and success. Same for the properties of apiAvailableBuses.
RootObject has a public field: apiStatus. That probably needs to be a a property with a getter/setter.
Moreover, apiAvailableBuses is plural, which is incorrect, since the data therein is of only one bus. Same for boardingpoints: the class contains data for a single point, not multiple.
Be consistent: if you use string, then also use bool and not Boolean.
I have a Model like this
public class Challenge
{
public int ID { get; set; }
public string Name { get; set; }
public string Blurb { get; set; }
public int Points { get; set; }
public string Category { get; set; }
public string Flag { get; set; }
public List<string> SolvedBy { get; set; }
}
public class ChallengeDBContext : DbContext
{
public DbSet<Challenge> Challenges { get; set; }
}
and then Controller like this. But I cannot update the List "SolvedBy", the next time I step through with the debugger, the list is still empty.
[HttpPost]
public string Index(string flag = "", int id=0)
{
Challenge challenge = db.Challenges.Find(id);
if (flag == challenge.Flag)
{
var chall = db.Challenges.Find(id);
if (chall.SolvedBy == null)
{
chall.SolvedBy = new List<string>();
}
chall.SolvedBy.Add(User.Identity.Name);
db.Entry(chall).State = EntityState.Modified;
db.SaveChanges();
//congrats, you solved the puzzle
return "got it";
}
else
{
return "fail";
}
}
is there any way around it to make a list of strings kept in the database?
EF don't know how to store an array in database table so it just ignore it. You can create another table/entity or use XML/JSON to store the list. You can serialize the list before saving and deserialize it after loading from database
A List<T> in a model would normally map to a second table, but in your DbContext you only have a single table. Try adding a second table.
public class ChallengeDBContext : DbContext
{
public DbSet<Challenge> Challenges { get; set; }
public DbSet<Solution> Solutions {get; set;}
}
public class Challenge
{
public int ID { get; set; }
public string Name { get; set; }
public string Blurb { get; set; }
public int Points { get; set; }
public string Category { get; set; }
public string Flag { get; set; }
public List<Solution> SolvedBy { get; set; }
}
public class Solution
{
public int ID { get; set; }
public string Name { get; set; }
}
Then your controller can use code along the lines of...
var chall = db.Challenges.Find(id);
if (chall.SolvedBy == null)
{
chall.SolvedBy = new List<Solution>();
}
chall.SolvedBy.Add(new Solution {Name=User.Identity.Name});
None of the above has been tested and I may have made some mistakes there, but the general principle I want to illustrate is the fact that you need another table. The List<T> represents a JOIN in SQL.
