One way to resolve this error is to convert the DataTable to an IEnumerable using LINQ and then bind it to the WPF control. Here is an example:

  1. Convert the DataTable to an IEnumerable using LINQ:
var data = dataTable.AsEnumerable().ToList();
  1. Set the ItemsSource property of the WPF control to the IEnumerable:
listBox.ItemsSource = data;

Make sure the type of the control's ItemsSource property is set to "IEnumerable" or "IEnumerable<t>".
