如何将数组转换为绑定列表？

Question

• 您能解释一下为什么这两个不同的输出会出现这种情况吗？

• 在描述中我翻译了代码以便更好地理解问题

• 如何转换 IBindingList 中的数组？因为不可能对我的 DataGridView 进行排序

代码：

public class ProductDALC
{
    public List<Product> ListProducts() //Product is the table name of my Database named DotNetStore
    {
        DotNetDataContext DataModel = new DotNetDataContext();
        var query = from objProduct in DataModel.Product.AsEnumerable()
                  select new Product { idProduct = objProducto.CodProduct, Name = objProduct.Name };

        return query.ToList();    
    }

    public Array ArrayProducts()
    {
        DotNetDataContext DataModel = new DotNetDataContext();
        var query = from objProduct in DataModel.Product.AsEnumerable()
                    select new
                    {     
                        idProduct = ("0000" + Convert.ToString(objProduct.idProduct)).Substring(("0000" + Convert.ToString(objProduct.idProduct)).Length - 4, 4),
                        Nombre = objProduct.Name,
                        Cantidad = objProduct.Quantity

                    };

        return query.ToArray();
    }
}

你试试这个：http://msdn.microsoft.com/en-us/library/ms132681.aspx

public BindingList<Product> ArrayProducts()
{
    DotNetDataContext DataModel = new DotNetDataContext();
    var query = from objProduct in DataModel.Product.AsEnumerable()
                select new Product
                {     
                    idProduct = ("0000" + Convert.ToString(objProduct.idProduct)).Substring(("0000" + Convert.ToString(objProduct.idProduct)).Length - 4, 4),
                    Nombre = objProduct.Name,
                    Cantidad = objProduct.Quantity 
                };

    return new BindingList<Customer>(query.ToList());
}
