ValueMember from ComboBox.Items[i] using WinForms c#

问题

I fill out a ComboBox using below code:

cbxLines.DisplayMember = "Value";
cbxLines.ValueMember = "Key";
cbxLines.DataSource = new BindingSource(GetProductionLines(), null);

private Dictionary<int, string> GetProductionLines()

Now I want to fill out a ListView with every DisplayMember from the ComboBox among other info:

lvSelectedSetup.Items.Clear();
for (int i = 0; i <= cbxLines.Items.Count - 1; i++)
{
     ListViewItem item = new ListViewItem();
     item.SubItems.Add(cbxLines.Items[i].ToString());  <-- How to Get DisplayMember
     item.SubItems.Add(cbxFromDate.Text);
     item.SubItems.Add(cbxToDate.Text);
     lvSelectedSetup.Items.Add(item);
}

But I don't know how to get either the ValueMember or DisplayMember from the ComboBox.

I was trying doing the following, but get stuck:

item.SubItems.Add(cbxLines.Items[i].GetType().GetProperty(cbxLines.ValueMember).GetValue(cbxLines,null))

Any Advice?

回答1:

Gets the key in the key/value pair.

   ((KeyValuePair<int, string>)cbxLines.Items[i]).Key

Gets the value in the key/value pair.

((KeyValuePair<int, string>)cbxLines.Items[i]).Value
