HI,
 
Ive got the following question. I already got this part working but i want to do it a more nice way.
 
now i get a customer witch contains a list of customers ( actually 1).
using a linq query i can get the firstname, lastname, adress wich are all strings.
 
Now i made this function so it won't be done in the form but on its businessLogic, but i'm kinda stuck. i;m doing something wrong here but can't figger out what.
 
  public List<string, string, string> GetValuesBySelectedCustomer(List items)
{
// test
var firstname= items.Select(i => i.firstname).ToList();
var lastname= items.Select(i => i.lastname).ToList();
var street= items.Select(i => i.street).ToList();

return new List<string, string, string>{firstname, lastname, street};

}
 
I get the following error.
 

Using the generic type 'List<T>' requires 1 type arguments TestHarness C:\Users\climburg.deanone\Downloads\calender 2\TestHarness\Form1.cs 27 Active
