I have a C# project and looking for simple solution for map one class object data to list of another class object.
This is my input class
public class RatesInput
{
public string Type1 { get; set; }
public string Break1 { get; set; }
public string Basic1 { get; set; }
public string Rate1 { get; set; }
public string Type2 { get; set; }
public string Break2 { get; set; }
public string Basic2 { get; set; }
public string Rate2 { get; set; }
public string Type3 { get; set; }
public string Break3 { get; set; }
public string Basic3 { get; set; }
public string Rate3 { get; set; }
}
This is my another class structure
public class RateDetail
{
public string RateType { get; set; }
public decimal Break { get; set; }
public decimal Basic { get; set; }
public decimal Rate { get; set; }
}
it has a object like below. (For easiering the understanding, I use hardcoded values and actually values assign from a csv file)
RatesInput objInput = new RatesInput();
objInput.Type1 = "T";
objInput.Break1 = 100;
objInput.Basic1 = 50;
objInput.Rate1 = 0.08;
objInput.Type2 = "T";
objInput.Break2 = 200;
objInput.Basic2 = 50;
objInput.Rate2 = 0.07;
objInput.Type3 = "T";
objInput.Break3 = 500;
objInput.Basic3 = 50;
objInput.Rate3 = 0.06;
Then I need to assign values to "RateDetail" list object like below.
List<RateDetail> lstDetails = new List<RateDetail>();
//START Looping using foreach or any looping mechanism
RateDetail obj = new RateDetail();
obj.RateType = //first iteration this should be assigned objInput.Type1, 2nd iteration objInput.Type2 etc....
obj.Break = //first iteration this should be assigned objInput.Break1 , 2nd iteration objInput.Break2 etc....
obj.Basic = //first iteration this should be assigned objInput.Basic1 , 2nd iteration objInput.Basic2 etc....
obj.Rate = //first iteration this should be assigned objInput.Rate1, 2nd iteration objInput.Rate2 etc....
lstDetails.Add(obj); //Add obj to the list
//END looping
Is there any way to convert "RatesInput" class data to "RateDetail" class like above method in C#? If yes, how to iterate data set?
Try this:
public class RatesList : IEnumerable<RateDetail>
{
public RatesList(IEnumerable<RatesInput> ratesInputList)
{
RatesInputList = ratesInputList;
}
private readonly IEnumerable<RatesInput> RatesInputList;
public IEnumerator<RateDetail> GetEnumerator()
{
foreach (var ratesInput in RatesInputList)
{
yield return new RateDetail
{
RateType = ratesInput.Type1,
Break = Convert.ToDecimal(ratesInput.Break1, new CultureInfo("en-US")),
Basic = Convert.ToDecimal(ratesInput.Basic1, new CultureInfo("en-US")),
Rate = Convert.ToDecimal(ratesInput.Rate1, new CultureInfo("en-US"))
};
yield return new RateDetail
{
RateType = ratesInput.Type2,
Break = Convert.ToDecimal(ratesInput.Break2),
Basic = Convert.ToDecimal(ratesInput.Basic2),
Rate = Convert.ToDecimal(ratesInput.Rate2, new CultureInfo("en-US"))
};
yield return new RateDetail
{
RateType = ratesInput.Type3,
Break = Convert.ToDecimal(ratesInput.Break3),
Basic = Convert.ToDecimal(ratesInput.Basic3),
Rate = Convert.ToDecimal(ratesInput.Rate3, new CultureInfo("en-US"))
};
}
}
IEnumerator IEnumerable.GetEnumerator()
{
return GetEnumerator();
}
}
And use:
var list = new RatesList(new List<RatesInput>() { objInput });
foreach (var item in list)
{
Console.WriteLine(item.Basic);
}
You can use Reflection to get the properties info like this:
var props = objInput.GetType().GetProperties();
var types = props.Where(x => x.Name.StartsWith("Type"))
.Select(x => x.GetValue(objInput)).ToList();
var breaks = props.Where(x => x.Name.StartsWith("Break"))
.Select(x => x.GetValue(objInput)).ToList();
var basics = props.Where(x => x.Name.StartsWith("Basic"))
.Select(x => x.GetValue(objInput)).ToList();
var rates = props.Where(x => x.Name.StartsWith("Rate"))
.Select(x => x.GetValue(objInput)).ToList();
List<RateDetail> lstDetails = new List<RateDetail>();
for (int i = 0; i < types.Count; i++)
{
lstDetails.Add(new RateDetail
{
RateType = types[i].ToString(),
Break = Convert.ToDecimal(breaks[i]),
Basic = Convert.ToDecimal(basics[i]),
Rate = Convert.ToDecimal(rates[i])
});
}

I am new to C# and OOP, in general, I've kinda hit a wall I am reading in this CSV using the CSV Helper package, but there are some unwanted rows, etc so I have cleaned it up by iterating over "records" and creating a new class LineItems.
But Now I appear to be a bit stuck. I know void doesn't return anything and is a bit of a placeholder. But How can I access all the instances of LineItems outside of this function?
public void getMapper()
{
using (var StreamReader = new StreamReader(#"D:\Data\Projects\dictUnitMapper.csv"))
{
using (var CsvReader = new CsvReader(StreamReader, CultureInfo.InvariantCulture))
{
var records = CsvReader.GetRecords<varMapper>().ToList();
foreach (var item in records)
{
if (item.name != "#N/A" && item.priority != 0)
{
LineItems lineItem = new LineItems();
lineItem.variableName = item.Items;
lineItem.variableUnit = item.Unit;
lineItem.variableGrowthCheck = item.growth;
lineItem.variableAVGCheck = item.avg;
lineItem.variableSVCheck = item.svData;
lineItem.longName = item.name;
lineItem.priority = item.priority;
}
}
}
}
}
public class LineItems
{
public string variableName;
public string variableUnit;
public bool variableGrowthCheck;
public bool variableAVGCheck;
public bool variableSVCheck;
public string longName;
public int priority;
}
public class varMapper
{
public string Items { get; set; }
public string Unit { get; set; }
public bool growth { get; set; }
public bool avg { get; set; }
public bool svData { get; set; }
public string name { get; set; }
public int priority { get; set; }
}
You should write your method to return a list.
public List<LineItems> GetMapper()
{
using (var StreamReader = new StreamReader(#"D:\Data\Projects\dictUnitMapper.csv"))
{
using (var CsvReader = new CsvHelper.CsvReader(StreamReader, CultureInfo.InvariantCulture))
{
return
CsvReader
.GetRecords<varMapper>()
.Where(item => item.name != "#N/A")
.Where(item => item.priority != 0)
.Select(item => new LineItems()
{
variableName = item.Items,
variableUnit = item.Unit,
variableGrowthCheck = item.growth,
variableAVGCheck = item.avg,
variableSVCheck = item.svData,
longName = item.name,
priority = item.priority,
})
.ToList();
}
}
}
Here's an alternative syntax for building the return value:
return
(
from item in CsvReader.GetRecords<varMapper>()
where item.name != "#N/A"
where item.priority != 0
select new LineItems()
{
variableName = item.Items,
variableUnit = item.Unit,
variableGrowthCheck = item.growth,
variableAVGCheck = item.avg,
variableSVCheck = item.svData,
longName = item.name,
priority = item.priority,
}
).ToList();
I am new to web api and C#. I am creating a function where I am calling values from table which has 33 rows. the query is this:
Select * from T_SVRS_Reg_Trans
I have created a model where I have put out properties like so:
public class UserModel
{
public int ID { get; set; }
public string OrgUnit { get; set; }
public string TDC { get; set; }
public string CustCode { get; set; }
public string CustName { get; set; }
public string DestCode { get; set; }
public string EMV { get; set; }
public string Service { get; set; }
public string SPCCode { get; set; }
public string SPCode { get; set; }
public string Remarks { get; set; }
public int Stage { get; set; }
public string Cost { get; set; }
public string SAPUpdate { get; set; }
public string Active { get; set; }
public string CreatedBy { get; set; }
public DateTime CreatedOn { get; set; }
public string UpdatedBy { get; set; }
public DateTime UpdatedOn { get; set; }
}
Now I am calling the table values to get added in these properties. My function for that is this:
[HttpPost]
[Route("GetTableValue")]
public IHttpActionResult GetTableValue()
{
try
{
UserModel objUserModel = new UserModel();
ManageUserData ObjManageUserData = new ManageUserData();
var sqlDataTable = ObjManageUserData.GetTableValue();
if (sqlDataTable.Rows.Count > 0)
{
for (int i = 0; (i < sqlDataTable.Rows.Count); i++)
{
objUserModel.OrgUnit=(sqlDataTable.Rows[i]["TRT_Org_ID"].ToString());
objUserModel.TDC = (sqlDataTable.Rows[i]["TRT_TDC_Code"].ToString());
objUserModel.CustCode = (sqlDataTable.Rows[i]["TRT_Cust_Code"].ToString());
objUserModel.CustName = (sqlDataTable.Rows[i]["TRT_Cust_Name"].ToString());
objUserModel.DestCode = (sqlDataTable.Rows[i]["TRT_Dest_Code"].ToString());
objUserModel.EMV = (sqlDataTable.Rows[i]["TRT_EMV"].ToString());
objUserModel.Service = (sqlDataTable.Rows[i]["TRT_Service"].ToString());
objUserModel.SPCCode = (sqlDataTable.Rows[i]["TRT_SPC_Code"].ToString());
objUserModel.SPCode = (sqlDataTable.Rows[i]["TRT_SP_Code"].ToString());
objUserModel.Remarks = (sqlDataTable.Rows[i]["TRT_Remarks"].ToString());
objUserModel.Stage = (int)(sqlDataTable.Rows[i]["TRT_Stage"]);
objUserModel.Cost = (sqlDataTable.Rows[i]["TRT_Cost_Imp"].ToString());
objUserModel.SAPUpdate = (sqlDataTable.Rows[i]["TRT_SAP_Update_Status"].ToString());
objUserModel.Active = (sqlDataTable.Rows[i]["TRT_IS_ACTIVE"].ToString());
objUserModel.CreatedBy = (sqlDataTable.Rows[i]["TRT_CREATED_BY"].ToString());
objUserModel.CreatedOn = (DateTime)(sqlDataTable.Rows[i]["TRT_CREATED_ON"]);
objUserModel.UpdatedBy = (sqlDataTable.Rows[i]["TRT_UPDATED_BY"].ToString());
objUserModel.UpdatedOn = (DateTime)(sqlDataTable.Rows[i]["TRT_UPDATED_ON"]);
}
}
return Ok(objUserModel);
}
catch (Exception ex)
{
return Content(HttpStatusCode.NoContent, "Something went wrong");
}
However I am noticing that only the last table value is added to the model and the rest of it is not. I want to add all 33 values in model form to the model mentioned. Is there any way to do this?
PLease help
}
You overwrite objUserModel each iteration. Create a new one inside the loop, add them to a List<UserModel>, returning that to your view.
Also consider dropping the archaic Hungarian notation (the "obj" prefix). Also consider using an ORM instead of mapping columns to properties using strings.
You should create a List or Array of type UserModel and adding items into it
try
{
List<UserModel> result = new List<UserModel>();
ManageUserData ObjManageUserData = new ManageUserData();
var sqlDataTable = ObjManageUserData.GetTableValue();
if (sqlDataTable.Rows.Count > 0)
{
for (int i = 0; (i < sqlDataTable.Rows.Count); i++)
{
UserModel objUserModel = new UserModel();
objUserModel.OrgUnit = (sqlDataTable.Rows[i]["TRT_Org_ID"].ToString());
objUserModel.TDC = (sqlDataTable.Rows[i]["TRT_TDC_Code"].ToString());
objUserModel.CustCode = (sqlDataTable.Rows[i]["TRT_Cust_Code"].ToString());
objUserModel.CustName = (sqlDataTable.Rows[i]["TRT_Cust_Name"].ToString());
objUserModel.DestCode = (sqlDataTable.Rows[i]["TRT_Dest_Code"].ToString());
objUserModel.EMV = (sqlDataTable.Rows[i]["TRT_EMV"].ToString());
objUserModel.Service = (sqlDataTable.Rows[i]["TRT_Service"].ToString());
objUserModel.SPCCode = (sqlDataTable.Rows[i]["TRT_SPC_Code"].ToString());
objUserModel.SPCode = (sqlDataTable.Rows[i]["TRT_SP_Code"].ToString());
objUserModel.Remarks = (sqlDataTable.Rows[i]["TRT_Remarks"].ToString());
objUserModel.Stage = (int)(sqlDataTable.Rows[i]["TRT_Stage"]);
objUserModel.Cost = (sqlDataTable.Rows[i]["TRT_Cost_Imp"].ToString());
objUserModel.SAPUpdate = (sqlDataTable.Rows[i]["TRT_SAP_Update_Status"].ToString());
objUserModel.Active = (sqlDataTable.Rows[i]["TRT_IS_ACTIVE"].ToString());
objUserModel.CreatedBy = (sqlDataTable.Rows[i]["TRT_CREATED_BY"].ToString());
objUserModel.CreatedOn = (DateTime)(sqlDataTable.Rows[i]["TRT_CREATED_ON"]);
objUserModel.UpdatedBy = (sqlDataTable.Rows[i]["TRT_UPDATED_BY"].ToString());
objUserModel.UpdatedOn = (DateTime)(sqlDataTable.Rows[i]["TRT_UPDATED_ON"]);
result.Add(objUserModel);
}
}
return Ok(result);
}
catch (Exception ex)
{
return Content(HttpStatusCode.NoContent, "Something went wrong");
}
You need to use the collection instead of single object UserModel.
[HttpPost]
[Route("GetTableValue")]
public IHttpActionResult GetTableValue()
{
try
{
ManageUserData ObjManageUserData = new ManageUserData();
var sqlDataTable = ObjManageUserData.GetTableValue();
List<UserModel> userModels = new List<UserModel>();
if (sqlDataTable.Rows.Count > 0)
{
for (int i = 0; (i < sqlDataTable.Rows.Count); i++)
{
var objUserModel = new UserModel()
objUserModel.OrgUnit = (sqlDataTable.Rows[i]["TRT_Org_ID"].ToString());
objUserModel.TDC = (sqlDataTable.Rows[i]["TRT_TDC_Code"].ToString());
objUserModel.CustCode = (sqlDataTable.Rows[i]["TRT_Cust_Code"].ToString());
objUserModel.CustName = (sqlDataTable.Rows[i]["TRT_Cust_Name"].ToString());
objUserModel.DestCode = (sqlDataTable.Rows[i]["TRT_Dest_Code"].ToString());
objUserModel.EMV = (sqlDataTable.Rows[i]["TRT_EMV"].ToString());
objUserModel.Service = (sqlDataTable.Rows[i]["TRT_Service"].ToString());
objUserModel.SPCCode = (sqlDataTable.Rows[i]["TRT_SPC_Code"].ToString());
objUserModel.SPCode = (sqlDataTable.Rows[i]["TRT_SP_Code"].ToString());
objUserModel.Remarks = (sqlDataTable.Rows[i]["TRT_Remarks"].ToString());
objUserModel.Stage = (int)(sqlDataTable.Rows[i]["TRT_Stage"]);
objUserModel.Cost = (sqlDataTable.Rows[i]["TRT_Cost_Imp"].ToString());
objUserModel.SAPUpdate = (sqlDataTable.Rows[i]["TRT_SAP_Update_Status"].ToString());
objUserModel.Active = (sqlDataTable.Rows[i]["TRT_IS_ACTIVE"].ToString());
objUserModel.CreatedBy = (sqlDataTable.Rows[i]["TRT_CREATED_BY"].ToString());
objUserModel.CreatedOn = (DateTime)(sqlDataTable.Rows[i]["TRT_CREATED_ON"]);
objUserModel.UpdatedBy = (sqlDataTable.Rows[i]["TRT_UPDATED_BY"].ToString());
objUserModel.UpdatedOn = (DateTime)(sqlDataTable.Rows[i]["TRT_UPDATED_ON"]);
userModels.Add(userModels);
}
}
return Ok(userModels);
}
catch (Exception ex)
{
return Content(HttpStatusCode.NoContent, "Something went wrong");
}
}
As you are expecting more than one row to be returned, you need to collect the rows as you iterate your result set into some sort of collection/list/array.
Try making a list of your UserModel
List<UserModel> objUserModels = new List<UserModel>();
And then adding each object to the list after each iteration of your for loop:
for (int i = 0; (i < sqlDataTable.Rows.Count); i++)
{
var objUserModel = new UserModel();
objUserModel.OrgUnit=(sqlDataTable.Rows[i]["TRT_Org_ID"].ToString());
objUserModel.TDC = (sqlDataTable.Rows[i]["TRT_TDC_Code"].ToString());
objUserModel.CustCode = (sqlDataTable.Rows[i]["TRT_Cust_Code"].ToString());
objUserModel.CustName = (sqlDataTable.Rows[i]["TRT_Cust_Name"].ToString());
objUserModel.DestCode = (sqlDataTable.Rows[i]["TRT_Dest_Code"].ToString());
objUserModel.EMV = (sqlDataTable.Rows[i]["TRT_EMV"].ToString());
objUserModel.Service = (sqlDataTable.Rows[i]["TRT_Service"].ToString());
objUserModel.SPCCode = (sqlDataTable.Rows[i]["TRT_SPC_Code"].ToString());
objUserModel.SPCode = (sqlDataTable.Rows[i]["TRT_SP_Code"].ToString());
objUserModel.Remarks = (sqlDataTable.Rows[i]["TRT_Remarks"].ToString());
objUserModel.Stage = (int)(sqlDataTable.Rows[i]["TRT_Stage"]);
objUserModel.Cost = (sqlDataTable.Rows[i]["TRT_Cost_Imp"].ToString());
objUserModel.SAPUpdate = (sqlDataTable.Rows[i]["TRT_SAP_Update_Status"].ToString());
objUserModel.Active = (sqlDataTable.Rows[i]["TRT_IS_ACTIVE"].ToString());
objUserModel.CreatedBy = (sqlDataTable.Rows[i]["TRT_CREATED_BY"].ToString());
objUserModel.CreatedOn = (DateTime)(sqlDataTable.Rows[i]["TRT_CREATED_ON"]);
objUserModel.UpdatedBy = (sqlDataTable.Rows[i]["TRT_UPDATED_BY"].ToString());
objUserModel.UpdatedOn = (DateTime)(sqlDataTable.Rows[i]["TRT_UPDATED_ON"]);
objUserModels.Add(objUserModel);
}
And then return your list of objects:
return Ok(objUserModels);
I need to populate a dropdown in my UI and hence added List object to the view model in my c# application. I am fetching the data in my controller code for the dropdown. What's the best way to assign data to the viewmodel object. Is linq an option?
I basically need to assign fundclasses to fundTrackRecord.FundClass
The main Viewmodel:
public class FundPerformanceVM
{
public FundPerformanceVM()
{
TrackRecord = new List<TrackRecordVM>();
}
public int FundId { get; set; }
public string FundName { get; set; }
public List<FundClassVM> FundClass { get; set; }
public string BenchmarkName1 { get; set; }
public string BenchmarkName2 { get; set; }
public List<TrackRecordVM> TrackRecord { get; set; }
public List<Tuple<string, string, string>> FundStatistics { get; set; }
}
public class FundClassVM
{
public int FundClassId { get; set; }
public string FundClass { get; set; }
}
Controller code:
var service = GetViewService<V_LEGAL_FUND_CLASS_SUMMARY>();
foreach (KeyValuePair<int, IEnumerable<FUND_PERFORMANCE>> entry in allPerformance)
{
var fundClasses = service.GetAll().Where(x => x.FUND_ID == entry.Key).Select(x => new { x.LEGAL_FUND_CLASS_ID, x.LEGAL_FUND_CLASS}).ToList();
var fundTrackRecord = new FundPerformanceVM();
fundTrackRecord.FundClass = ??;
If I understood correctly the structure of your model, you can try this:
fundTrackRecord.FundClass = fundClasses.Select(fc => new FundClassVM
{
FundClassId = fc.LEGAL_FUND_CLASS_ID,
FundClass = fc.LEGAL_FUND_CLASS
}).ToList();
You can also do this directly, replacing the code:
var fundClasses = service.GetAll().Where(x => x.FUND_ID == entry.Key).Select(x => new { x.LEGAL_FUND_CLASS_ID, x.LEGAL_FUND_CLASS}).ToList();
var fundTrackRecord = new FundPerformanceVM();
With:
var fundTrackRecord = new FundPerformanceVM();
fundTrackRecord.FundClass = service.GetAll().
Where(x => x.FUND_ID == entry.Key).
Select(fc => new FundClassVM
{
FundClassId = fc.LEGAL_FUND_CLASS_ID,
FundClass = fc.LEGAL_FUND_CLASS
}).ToList();
All I want to do is return multiple reader.cast<> so that i can use 2 sqlcommands.
var first =reader.Cast<IDataRecord>().Select(x => new LocationInfo()
{
Names = x.GetString(0),
Values = Math.Round(x.GetDouble(1), 2).ToString("#,##0.00"),
ValuesDouble = x.GetDouble(1)
}).ToList();
reader.NextResult();
var second=reader.Cast<IDataRecord>().Select(x => new LocationInfo()
{
Names2 = x.GetString(0),
Values2 = Math.Round(x.GetDouble(1), 2).ToString("#,##0.00"),
ValuesDouble2 = x.GetDouble(1)
}).ToList();
All I want to do is return var first and var second. Please help :(
I'm using this Location.cs for parameters:
namespace MVCRealtime
{
public class LocationInfo
{
public string Names { get; set; }
public string Values { get; set; }
public double ValuesDouble { get; set; }
public string Names2 { get; set; }
public string Values2 { get; set; }
public double ValuesDouble2 { get; set; }
}
}
public static class ReaderHelper
{
public static IEnumerable<TElem> GetData<TElem>(this IDataReader reader, Func<IDataRecord, TElem> buildObjectDelegat)
{
while (reader.Read())
{
yield return buildObjectDelegat(reader);
}
}
}
// ...
var result = reader.GetData(x => new LocationInfo()
{
Names = x.GetString(0),
Values = Math.Round(x.GetDouble(1), 2).ToString("#,##0.00"),
ValuesDouble = x.GetDouble(1)
}).Take(2);
So you get 1st var in 1st element of the result and 2nd var in 2nd element.
I have 2 types of string: Mer and Spl
// Example
string testMer = "321|READY|MER";
string testSpl = "321|READY|SPL";
Then I will split them:
var splitMer = testMer.Split('|');
var splitSpl = testSpl.Split('|');
I have an object to save them
public class TestObject
{
public int id { get; set; }
public string status { get; set; }
public string type { get; set; }
}
Question: How to convert the Array into the TestObject?
var converted = new TestObject
{
id = int.Parse(splitMer[0]),
status = splitMer[1],
type = splitMer[2]
};
You will need to add some error checking.
var values = new List<string> { "321|READY|MER", "321|READY|SPL" };
var result = values.Select(x =>
{
var parts = x.Split(new [] {'|' },StringSplitOptions.RemoveEmptyEntries);
return new TestObject
{
id = Convert.ToInt32(parts[0]),
status = parts[1],
type = parts[2]
};
}).ToArray();
You just need to use object initializers and set your properties.By the way instead of storing each value into seperate variables, use a List.Then you can get your result with LINQ easily.
var splitMer = testMer.Split('|');
var testObj = new TestObject();
testObj.Id = Int32.Parse(splitMer[0]);
testObj.Status = splitMer[1];
testObj.type = splitMer[2];
How about adding a Constructor to your Class that takes a String as a Parameter. Something like this.
public class TestObject
{
public int id { get; set; }
public string status { get; set; }
public string type { get; set; }
public TestObject(string value)
{
var valueSplit = value.Split('|');
id = int.Parse(valueSplit[0]);
status = valueSplit[1];
type = valueSplit[2];
}
}
Usage:
TestObject tst1 = new TestObject(testMer);
TestObject tst2 = new TestObject(testSpl);
