我有以下方法在DataGridView上加载产品

private void LoadProducts(List<Product> products)
{
    Source.DataSource = products;  // Source is BindingSource
    ProductsDataGrid.DataSource = Source;
}

现在我试图让我回来保存它们如下图所示.

private void SaveAll()
{
   Repository repository = Repository.Instance;
   List<object> products = (List<object>)Source.DataSource; 
   Console.WriteLine("Este es el número {0}", products.Count);
   repository.SaveAll<Product>(products);
   notificacionLbl.Visible = false;
}

但是我得到了InvalidCastException这条线:

List<object> products = (List<object>)Source.DataSource;

那么如何将DataSource转换为List呢？
