Thanks to all for all your precious time.
i got solution by using below code :-
var loan = context.loanmasters.Where(m => m.MemberUniqueId == MemberUniqueId).Select(m => new
{
LoanAccountNo = m.LoanAccountNo.ToString(),
StartDate = m.StartDate.ToString(),
Tenure = m.Tenure.ToString(),
OutstandingPrinciple = m.OutstandingPrinciple.ToString(),
InterestRate = m.InterestRate.ToString(),
LoanAmount = m.LoanAmount.ToString(),
EMI = m.EMI.ToString()
});
var listOfLoanStringLists = new L.List<String[]>();
foreach (var loanRec in loan)
{
listOfLoanStringLists.Add(new String[] { loanRec.LoanAccountNo, loanRec.StartDate, loanRec.Tenure, loanRec.OutstandingPrinciple, loanRec.InterestRate, loanRec.LoanAmount, loanRec.EMI });
}
ViewBag.LoanMaster = JsonConvert.SerializeObject(listOfLoanStringLists);
