I'm trying to create a Pivot using LINQ with dynamic columns. I have created a Pivot in SQL Server where you do not know which columns are going to get used. But don't know how to transfer that into LINQ. Does anyone have links for me to get started on?
Cheers

List<CustData> myList = GetCustData();
var query = myList
.GroupBy(c => c.CustId)
.Select(g => new {
CustId = g.Key,
Jan = g.Where(c => c.OrderDate.Month == 1).Sum(c => c.Qty),
Feb = g.Where(c => c.OrderDate.Month == 2).Sum(c => c.Qty),
March = g.Where(c => c.OrderDate.Month == 3).Sum(c => c.Qty)
});
this is the answer from David B in this url
