How can I bind a collection of C# 7.0 tuple type values to a System.Windows.Forms.Listbox and set the display member to one of the elements?

Question

I have a System.Windows.Forms.Listbox and a collection of tuple type values I've created. That is, the new tuple type introduced in C# 7.0. I'm trying to bind the collection to the Listbox and set the DisplayMember to one of the elements in the tuple. Here's an example:

var l = new List<(string name, int ID)>()
{
    ("Bob", 1),
    ("Mary", 2),
    ("Beth", 3)
};

listBox1.DataSource = l;
listBox1.DisplayMember = "name";

That doesn't work, though. With the older-style Tuple<T> you could supposedly do what's described in this answer:

listBox1.DisplayMember = "Item1";
listBox1.ValueMember = "Item3";   // optional

That doesn't work either. Here's what I'm seeing in both cases:

How can I accomplish this?

Answer 1

Unfortunately C#7 value tuples cannot be used for data binding because they use fields, while Windows Forms standard data binding works only with properties.

Answer 2

Ivan's answer, definitely describes the case. As a workaround you can use Format event of ListBox to show name filed:

private void listBox1_Format(object sender, ListControlConvertEventArgs e)
{
    e.Value = (((string name, int ID))e.ListItem).name;
}
