返回加入Linq C#

Question

我正在尝试将连接返回到我的班级,它给了我以下错误.

错误1无法将类型'System.Collections.Generic.List'隐式转换为'System.Collections.Generic.List'C:\ Projetos_ASP.NET\AdvanceTechniques\Models\Repository\ProductRepository.cs 40 30 AdvanceTechniques

请遵循以下代码.

public List<Line> Get()
{
    return context.
        Lines.
        Join(
            context.Products,
            lines => lines.ID,
            products => products.LineID,
            ((products, lines)
                => new { lines, products}
        )).
        OrderByDescending(products => products.products.ID).ToList();
}

关注我的实体

public partial class Line
    {
        public Line()
        {
            this.Products = new List<Product>();
        }
        [Required]
        public long ID { get; set; }
        [Required]
        public string Name { get; set; }
        [Required]
        public string Slug { get; set; }
        [Required]
        public string DesktopImage { get; set; }
        [Required]
        public string MobileImage { get; set; }
        [Required]
        public string AltImage { get; set; }
        [Required]
        public int Position { get; set; }
        [Required]
        public bool IsActive { get; set; }

        public virtual List<Product> Products { get; set; }
    }

Answer 1

您不需要Join为每一行返回产品,您只需要包含产品然后返回它们,如:

return context.Lines.Include("Products").ToList();
