Joining in LINQ to select a sublist within a list - asp.net-mvc-3

Question

I have two classes as follows:
public class HRM_SERVICE_PERD_BNFT_DTLModel
{
public string SRVC_PERD_BNFT_CODE { get; set; }
public string RTR_BNFT_CODE { get; set; }
public string RTR_BNFT_NAME { get; set; }
public string RTR_BNFT_CALC_MODE { get; set; }
public string SAL_HEAD_CODE { get; set; }
public string SAL_HEAD_NAME { get; set; }
public string RTR_BNFT_IN_PERCENT { get; set; }
public string RTR_BNFT_AMOUNT { get; set; }
public string RTR_BNFT_INACTV_DATE { get; set; }
public short? RTR_BNFT_SLNO { get; set; }
}
public class HRM_RETIREMENT_BENEFITModel : BaseModel
{
public string RTR_BNFT_CODE { get; set; }
public string RTR_BNFT_NAME { get; set; }
public string RTR_BNFT_SRTNM { get; set; }
public string RTR_BNFT_REM { get; set; }
public short? RTR_BNFT_SLNO { get; set; }
}
Now I want to select data from the first model for a specific 'SRVC_PERD_BNFT_CODE', then I need to select the 'RTR_BNFT_NAME' from the second table for all the filtered data along with some other value from the first model. I'm trying kind of joining, but not getting the name. It's showing system.collection.string instead of value.
Here is what I'm trying so far:
public List<HRM_SERVICE_PERD_BNFT_DTLModel> GetBenefitData(string mstcode)
{
var model2 = DataContext.HRM_SERVICE_PERD_BNFT_DTL.AsEnumerable().Where(m => m.SRVC_PERD_BNFT_CODE == mstcode).Select(s=>s).ToList();
var model = DataContext.HRM_SERVICE_PERD_BNFT_DTL.AsEnumerable().Where(m => m.SRVC_PERD_BNFT_CODE == mstcode)
.Select(s => new HRM_SERVICE_PERD_BNFT_DTLModel
{
RTR_BNFT_CODE = s.RTR_BNFT_CODE,
RTR_BNFT_SLNO = s.RTR_BNFT_SLNO,
RTR_BNFT_CALC_MODE = s.RTR_BNFT_CALC_MODE,
RTR_BNFT_AMOUNT = (s.RTR_BNFT_AMOUNT).ToString(),
RTR_BNFT_NAME = (from x in model2
join c in DataContext.HRM_RETIREMENT_BENEFIT on x.RTR_BNFT_CODE equals c.RTR_BNFT_CODE into p
from b in p.AsEnumerable()
select b.RTR_BNFT_NAME).ToList().ToString(),
RTR_BNFT_IN_PERCENT = (s.RTR_BNFT_IN_PERCENT).ToString()
}).ToList();
return model;
}
What I'm doing wrong? Please help.

Answer 1

Following is suspicious.
.ToList().ToString()
Remove the ToString part and replace it with something like FirstorDefault, then it should work.
Reason for getting something like System.Collection.String is that List<T>.ToString() is usually typename until it is overridden in some way.
Following minimal snipped produce System.Collections.Generic.List1[System.String]`
List<String> list = new List<String>();
var str = list.ToString();
Console.WriteLine(str); //System.Collections.Generic.List`1 [ System.String ]
