Question

private string Paidby

        string paidBy = string.Empty;

        if(this.PartnershipFundingEntity!=null)
        {
            paidBy = (PartnershipFundingEntity.Where(x => x.FundingTypeId == 1).Select(y => y.CfPurposeList)).ToString();
        }

    }
}

receiving error like ->

System.Linq.Enumerable+WhereSelectListIterator`2[Tdsb.Aris.Pims.Entity.PartnershipFunding,System.String]

Answer 1

Your question suggests an error, but the value seems to be the type name that is pushed into paidBy string :

paidBy = (PartnershipFundingEntity
   .Where(x => x.FundingTypeId == 1)          // where iterator at this point
   .Select(y => y.CfPurposeList))             // WhereSelectListIterator at this point
   .ToString();                               // ToString() returns type name by default

I think you should have something like this:

paidBy = PartnershipFundingEntity
   .Where(x => x.FundingTypeId == 1)
   .First(x => <boolean condition to select one element>)
   .PaidByProp;

This works if a single element is found, otherwise FirstOrDefault should be used and tested for null. I think ?. (null conditional) can be used to narrow to a single instruction.
