How to update a datatable field in linq to sql with a value from another datatable field
I tried this, but it does not update the values.
dt1.Rows.Cast<DataRow>().J
r1 => new { p1 = r1["ID"], p2 = r1["Date"] },
r2 => new { p1 = r2["ID"], p2 = r2["Date"] },
(r1, r2) => new { r1, r2 }).ToList()
.ForEach(o => o.r1.SetField("Price", o.r2["Price"]));
dt1.Rows.Cast<DataRow>().J
r1 => new { p1 = r1["ID"], p2 = r1["Date"] },
r2 => new { p1 = r2["ID"], p2 = r2["Date"] },
(r1, r2) => new { r1, r2 }).ToList()
.ForEach(o => o.r1.SetField("Price", o.r2["Price"]));

It looks like you are using a DataTable object and NOT Linq to SQL is that correct?

Yes, I have two datatables,
I need to update the values in dt1 if they qualify on the join in dt2

Sorry Fernando, I am using LINQ to SQL, nothing to do with database updates.
Just wanted to update certain rows in datatable on certain conditions
