How to insert into an enumerable list, which is an member of another list

I have an AcadamicFee list, at one point in time I want to insert an item under Fee. So that, it should add like Fee[1], Fee[2].modified the code like below.
I want to insert one new item under Fee list. But it didn't reflect. How to update the AcadamicFee list through Linq?
Thanks in advance.
AcadamicFee[0]
{
----
----
----
TermDetails [0]
{
---
Fee[0]
Fee[1]
Fee[2]
}
}
public class Fee
{
public int FeeID { get; set; }
public string FeeName { get; set; }
public string FeeAmount { get; set; }
public string IsFineApplicable { get; set; }
public string LastDate { get; set; }
}
public class Ter
{
public int TermID { get; set; }
public string TermName { get; set; }
public IEnumerable<Fee> FeeDetails { get; set; }
}
public class AcadamicFee
{
public int id { get; set; }
public string AdmissionID { get; set; }
public string StudentName { get; set; }
public int Class { get; set; }
public string AcadamicYear { get; set; }
public Nullable<int> TotalPaid { get; set; }
public Nullable<int> AcadamicAmount { get; set; }
public Nullable<int> BalanceAmount { get; set; }
public IEnumerable<Term> TermDetails { get; set; }
}
Any clue how to do with Linq? I tried something like this:
for (var i = 0; i < fees.Count; i++)
{
bool termDetailsExist = acadamic_fee.Any(a => a.TermDetails.Any(b => b.TermID == fees[i].TermID));
if (termDetailsExist)
{
foreach (AcadamicFeeModel acm in acadamic_fee)
{
foreach (TermModel trm in acm.TermDetails)
{
if (trm.TermID == fees[i].TermID)
{
List<FeeModel> FeeType = new List<FeeModel>();
FeeType.Add(new FeeModel
{
FeeID = fees[i].FeeID,
FeeName = fees[i].FeeName,
FeeAmount = fees[i].FeeAmount,
IsFineApplicable = fees[i].IsFineApplicable,
LastDate = fees[i].LastDate,
});
trm.FeeDetails.ToList().AddRange(FeeType);
}
}
}
}
}

trm.FeeDetails.ToList().AddRange(FeeType);
You've created a new List<FeeModel>, added a copy of the FeeDetails sequence, added a new FeeModel object, and then thrown the new list away.
You need to store the modified list in the property - for example:
foreach (TermModel trm in acm.TermDetails)
{
if (trm.TermID == fees[i].TermID)
{
List<FeeModel> FeeType = new List<FeeModel>();
FeeType.Add(new FeeModel
{
FeeID = fees[i].FeeID,
FeeName = fees[i].FeeName,
FeeAmount = fees[i].FeeAmount,
IsFineApplicable = fees[i].IsFineApplicable,
LastDate = fees[i].LastDate,
});
FeeType.AddRange(trm.FeeDetails);
trm.FeeDetails = FeeType;
}
}

How do I LINQ nested lists to JSON in Web Api 2?

I am creating a web api that returns Json. My out put looks like this:
[
{
"NodeID":1252,
"CASNumber":"1333-86-4",
"EINECSCode":"215-609-9",
"EUIndex":"215-609-9",
"Duty":"No",
"Prohibited":"No",
"Unwanted":"No",
"IsReach":"No",
"SubstanceName":"Carbon black",
"GroupName":"Renault Complete",
"Portion":0.100000
},
{
"NodeID":1252,
"CASNumber":"1333-86-4",
"EINECSCode":"215-609-9",
"EUIndex":"215-609-9",
"Duty":"No",
"Prohibited":"No",
"Unwanted":"No",
"IsReach":"No",
"SubstanceName":"Carbon black",
"GroupName":"Renault Orange",
"Portion":0.100000
}
]
I Am trying to create nested Json with an ouptut like this:
{
"NodeID":1252,
"CASNumber":"1333-86-4",
"EINECSCode":"215-609-9",
"EUIndex":"215-609-9",
"Duty":"No",
"Prohibited":"No",
"Unwanted":"No",
"IsReach":"No",
"SubstanceName":"Carbon black",
"GroupName":[
{
"name":"Renault Complete"
},
{
"name":"Renault Orange"
}
],
"Portion":0.100000
}
This is my class:
public class BasicSubstances
{
public int NodeID { get; set; }
public string CASNumber { get; set; }
public string EINECSCode { get; set; }
public string EUIndex { get; set; }
public string Duty { get; set; }
public string Prohibited { get; set; }
public string Unwanted { get; set; }
public string IsReach { get; set; }
public string SubstanceName { get; set; }
public string GroupName { get; set; }
public decimal ?Portion { get; set; }
}
And this is my controller:
public List<BasicSubstances> GetBasicSubstance(string partNumber, string version, int nodeID, int parentID )
{
IMDSDataContext dc = new IMDSDataContext();
List<BasicSubstances> results = new List<BasicSubstances>();
foreach (spGetBasicSubstanceResult part in dc.spGetBasicSubstance( partNumber, version, nodeID, parentID))
{
results.Add(new BasicSubstances()
{
NodeID = part.NodeID,
CASNumber = part.CASNumber,
EINECSCode = part.EINECSCode,
EUIndex = part.EINECSCode,
Duty = part.Duty,
Prohibited = part.Prohibited,
Unwanted = part.Unwanted,
IsReach = part.ISReach,
SubstanceName = part.SynonymName,
GroupName = part.GroupName,
Portion = part.Portion
});
}
return results;
}
My Json looks like the first output, I need it to look like the second output.
I totally lost, any help would be appreciated.

Well, you can try the following:
Your models:
public class BasicSubstanceViewModel
{
public int NodeID { get; set; }
public string CASNumber { get; set; }
public string EINECSCode { get; set; }
public string EUIndex { get; set; }
public string Duty { get; set; }
public string Prohibited { get; set; }
public string Unwanted { get; set; }
public string IsReach { get; set; }
public string SubstanceName { get; set; }
public List<GroupName> GroupName { get; set; }
public decimal ?Portion { get; set; }
}
public class GroupName
{
public string Name { get; set; }
}
Your method:
public BasicSubstanceViewModel GetBasicSubstance(string partNumber, string version, int nodeID, int parentID )
{
IMDSDataContext dc = new IMDSDataContext();
var spResult = dc.spGetBasicSubstance( partNumber, version, nodeID, parentID).ToList();
if(!spResult.Any())
{
return null;
}
var firstPart = spResult[0];
var result = new BasicSubstanceViewModel
{
NodeID = firstPart.NodeID,
CASNumber = firstPart.CASNumber,
EINECSCode = firstPart.EINECSCode,
EUIndex = firstPart.EINECSCode,
Duty = firstPart.Duty,
Prohibited = firstPart.Prohibited,
Unwanted = firstPart.Unwanted,
IsReach = firstPart.ISReach,
SubstanceName = firstPart.SynonymName,
GroupName = spResult.Select(p => new GroupName { Name = p.GroupName }).ToList(),
Portion = firstPart.Portion
};
return result;
}
Hope it will help.

c# POST json not working as expected?

managed to get it working by changing the content-type to :

i was debugging with charles and the python version was posting a json formated form, changed the c# content type to match and now works a treat
Many Thanks for your code and help.

Custom Mapping Dapper.NET

I could done like this but I think there should be a way to do this better;
Resource.ResourceIncrease resource = new Resource.ResourceIncrease();
using (IDbConnection connection = OpenConnection())
{
dynamic reader = connection.Query<dynamic>("UserResourceGet", new { UserId = UserId }, commandType: CommandType.StoredProcedure).SingleOrDefault();
resource.Wood.value = reader.Wood;
resource.Wood.increase = reader.WoodIncome;
resource.Food.value = reader.Food;
resource.Food.increase = reader.FoodIncome;
resource.Stone.value = reader.Stone;
resource.Stone.increase = reader.StoneIncome;
resource.Gold.value = reader.Gold;
resource.Gold.increase = reader.GoldIncome;
}
return resource;
SQL SP >
SELECT Wood, Food, Stone, Gold, WoodIncome, FoodIncome, StoneIncome, GoldIncome
FROM Resources WHERE UserId = #UserId
Class >
public class Resource
{
public int Wood { get; set; }
public int Food { get; set; }
public int Stone { get; set; }
public int Gold { get; set; }
}
public class ResourceIncrease
{
public Increase Wood{ get; set; }
public Increase Food { get; set; }
public Increase Stone { get; set; }
public Increase Gold { get; set; }
public ResourceIncrease()
{
this.Wood = new Increase();
this.Food = new Increase();
this.Stone = new Increase();
this.Gold = new Increase();
}
}
public class Increase
{
public int value { get; set; }
public int increase { get; set; }
}

I would create a class that match the return of the SP, and then would use AutoMapper (http://automapper.org/) to map that class to the ResourceIncrease class.

EF5 The changes to the database were committed successfully ... Unable to set field/property

I have been searching for days now trying to figure this one out. It saves my records correctly but throws the following error:
The changes to the database were committed successfully, but an error occurred while updating the object context. The ObjectContext might be in an inconsistent state. Inner exception message: Unable to set field/property Actors on entity type BOR.DataModel.StagComplaint. See InnerException for details.

This is the client side code I am using to create the Complaint:
public int AddParcelsToStagingComplaint(List<string> parcelIDs, string userID) {
StagComplaint comp = new StagComplaint();
int Result = 0;
using (BORServiceClient db = new BORServiceClient()) {
comp = new StagComplaint() {
BuildingValue = 111222,
Category = "*",
LandValue = 222333,
Number = "*",
TaxYear = DateTime.Now.Year,
ComplaintTypeID = 1,
UserIdentification = userID,
CreationDate = DateTime.Now,
};
StagAddress ca = new StagAddress() { Line1 = "670 Harvard Blvd", City = "Cleveland", State = "OH", ZipCode = "44113", };
List<StagPhone> ps = new List<StagPhone>();
ps.Add(new StagPhone() { Number = "5556664646", Type = PhoneTypes.Home, UserIdentification = userID, CreationDate = DateTime.Now, });
comp.Actors.Add(
new StagActor() {
Name = "Joe Schmoe",
Address = ca,
Phones = ps,
RoleID = 1,
UserIdentification = userID,
CreationDate = DateTime.Now,
}
);
StagAddress aa = new StagAddress() {
City = wp.Address.City,
Line1 = wp.Address.Line1,
Line2 = wp.Address.Line2,

ZipCode = wp.Address.ZipCode,
};
ps = new List<StagPhone>();
ps.Add(new StagPhone() { Number = "4448887878", Type = PhoneTypes.Work, UserIdentification = userID, CreationDate = DateTime.Now, });
StagParcel p = new StagParcel() {
Address = new StagAddress() { Line1 = "4 Oxford Drive", City = "Hudson", State = "OH", ZipCode = "44236" },
BuildingValue = wp.BuildingValue,
LandUseCode = wp.LandUseCode,
LandValue = wp.LandValue,
NeighborhoodCode = wp.NeighborhoodCode,
Number = wp.Number,
Owner = new StagActor() { Name = "Owner Person", Address = aa, RoleID = 2, Phones = ps, UserIdentification = userID, CreationDate = DateTime.Now, },
OwnerOpinion = wp.OwnerOpinion,
SchoolBoardID = wp.SchoolBoardID,
SchoolDistrict = wp.SchoolDistrict,
TaxDistrict = wp.TaxDistrict,
UserIdentification = userID,
CreationDate = DateTime.Now,
};
comp.Parcels.Add(p);
ServiceResponse<int> saved = db.AddComplaint((ComplaintBase)comp, Contexts.Staging, userID);
if (saved.WasSuccessful)
Result = saved.Result;
} // using the database
return Result;
} // AddParcelsToStagingComplaint - Method
Here is the WCF method that gets called:
using (StagComplaintRepo cr = new StagComplaintRepo()) {
cr.Add((StagComplaint)complaint, userID);
if (cr.Save()) {
Result.Result = complaint.ID;
Result.WasSuccessful = true;
} else {
Result.AddException(string.Format("Unable to create a new Complaint in the {0} context.", context));
} // if the save was successful
} // using the Complaint Repository
And here is the BaseRepository that has the Save and Add methods:
public abstract class BaseRepository<T> : IDisposable, IRepository<T> where T : class {
public virtual bool Save(bool detectChanges = false) {
if (detectChanges == true)
this.Entities.ChangeTracker.DetectChanges();
return (this.Entities.SaveChanges() > 0);
}
public virtual void Add(T entity, string userID) {
this.Entities.Set<T>().Add(entity);
}
...
}
It fails on the above this.Entities.SaveChanges() call with the error mentioned at the top of this post. There is no extra inner exception. If I only fill in the Complaint properties that are required and are part of that object, it works. But once I add a Parcel with an Actor it fails.
I assume it is something simple, perhaps a switch needs to be turned on or off. But similar errors all seem to reference AcceptChanges and that is not the issue here. At least based on the error message. Any help would be appreciated.
