Convert object type

Hello good afternoon to everyone. could you please help me with the following

I would like to bring to a datagridvew the corresponding sales between two date ranges

for this I have the following code

namespace CapaLogica
{
public class VentasEntreFechasDTO
{
public string NumeroVenta { get; set; }
public string Producto { get; set; }
public string Unidad { get; set; }
public decimal Precio { get; set; }
public int Cantidad { get; set; }
public decimal ValorFila { get; set; }
//
public static List Ventas(DateTime Inicio, DateTime Fin)
{
using (GourmetEntities db = new GourmetEntities())
{
var li = db.tblMaestroVentas.Include(x => x.tblDetalleVentas).Where(x => x.FechaVenta >= Inicio && x.FechaVenta <= Fin);
return (List)li;
}
}
}
}

this code apparently doesn't show me any error, but when I try to load it to a datagridview it shows me an error

private void BtnBuscar_Click(object sender, EventArgs e)
{
if(VerificarRangoFechas())
{
DataGridViewVentaEntreFechas.DataSource = VentasEntreFechasDTO.Ventas(DtpDesde.Value.Date, DtpHasta.Value.Date);
}
}

Please how can I solve this error since I need to visualize sales between date ranges

please help
