Group by Operation in Linq.
List<string>
ls = new List<string>();
using (LinqModel.LinqEntities
ST1 = new LinqModel.LinqEntities())
{
var V = (from State in ST1.State_Master
group
State by State.CountryID into temp
select new
{
T1 =
temp.Key.Value,
T2 = temp
}).ToList();
foreach (var c in V)
{
for
(int i = 0; i < c.T2.ToList().Count; i++)
{
ls.Add(c.T2.ToList()[i].StateName);
}
}
};
// Group by With
Linq using Lambada expression
// Same Result as above
using (LinqModel.LinqEntities
ST1 = new LinqModel.LinqEntities())
{
var vLambada = ST.State_Master.GroupBy(state =>
state.CountryID).ToList();
foreach (var
state in vLambada)
{
for
(int i = 0; i < state.Count(); i++)
{
ls.Add(state.ToList()[i].StateName);
}
}
};
Rpt.DataSource = ls;
Rpt.DataBind();
