In this example, I will show you to select distinct records from list in linq and bind to a combobox in windows application using c# .net.
I want to bind the list of countries to a combobox using c# .net. The linq Distinct() guarantees to remove duplicate records from the List.
private void LoadCountries()
{
var countries = (from c in db.Orders
select new { c.ShipCountry }).Distinct().ToList();
cboCountry.DataSource = countries;
cboCountry.ValueMember = "shipcountry";
cboCountry.DisplayMember = "shipcountry";
}
