Question

我正在使用此代码，但无效

List<UrunListesi> DegiskenListesi = new List<UrunListesi>();
DegiskenUrunListesi = (from UL in DB.UrunListesi
                       where IDListesi.Contains(UL.KategoriID.ToString()) && UL.Durum == true
                       orderby UL.id descending
                       select UL).ToList();

浏览器错误

“CS0029：无法隐式转换类型 System.Collections.Generic.List<UrunListesi> [c：\ Windows \ Microsoft.NET \ Framework \ v4.0.30319 \ mscorlib.dll]'到 System.Collections.Generic.List<UrunListesi> [C：\的Windows \ Microsoft.NET \框架\ v4.0.30319 \ mscorlib.dll中]'“

我试过这条线，但这也行不通了

IEnumerable<UrunListesi> DegiskenUrunListesi = null;
DegiskenUrunListesi = (from UL in DB.UrunListesi
                       where IDListesi.Contains(UL.KategoriID.ToString()) && UL.Durum == true
                       orderby UL.id descending
                       select UL).ToList();

的DbContext

public partial class MySiteDBEntities : DbContext
    {
        public MySiteDBEntities()
            : base("name=MySiteDBEntities")
        {
        }

        protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            throw new UnintentionalCodeFirstException();

Answer 1

我解决了这个问题。

我在dbcontext中有UrunListesi类。我有同名UrunListesi.aspx文件。这就是整个问题。

感谢所有回答。

Answer 2

尝试：

var list = (from UL in DB.UrunListesi
            where IDListesi.Contains(UL.KategoriID.ToString()) && UL.Durum == true
            orderby UL.id descending
            select UL).ToList();
