Answer 1

You’re looking to use the ValueMember and DisplayMember properties of the combobox. MSDN Example

Short sample:

public class Foo
{
    public int ID { get; private set; }
    public string Name { get; private set; }

    public class Foo(int id, string name)
    {
        ID = id;
        Name = name;
    }
}

Then just make sure to set ID as the ValueMember and Name as the DisplayMember. Add a collection of Foo’s and you’re all set.
