Storing 2 columns into a List

Question

How can I store data from 2 columns (from a database) in a List

List<string> _items = new List<string>();

Any help is appreciated

Answer 1

You create a class that will represent a row with 2 columns:

public class Foo
{
    // obviously you find meaningful names of the 2 properties

    public string Column1 { get; set; } 
    public string Column2 { get; set; }
}

and then you store in a List<Foo>:

List<Foo> _items = new List<Foo>();
_items.Add(new Foo { Column1 = "bar", Column2 = "baz" });

Answer 2

Use a tuple struct like KeyValuePair

List<KeyValuePair<string, string>> _items = new List<KeyValuePair<string, string>>();
_items.Add(new KeyValuePair<string, string>(foo, bar));
