let us assume object name with data is listDetails

(from item in listDetails

group item by new{item.Branch.BranchId,item.Month.MonthId} into grouping
select new ListDetailsBE()
{
ListId =grouping.FirstOrDefault().ListId,
Month = grouping.FirstOrDefault().Month.MonthName,
MonthId = grouping.Key.MonthId,
Amount = grouping.Sum(x=>x.Amount),
BranchId = grouping.Key.BranchId,
BranchName = grouping.FirstOrDefault().Branch.BranchName
}).ToList();
