我將創建一個模塊,用於使用MVC C#將產品添加到期望列表中。爲此,我使用了實體框架。我在模型文件夾中創建了dbml類。我在去增加產品至我的喜愛我得到的錯誤是這樣的:獲取錯誤「表<WishList>」不包含'添加'的定義,也沒有包含edmx linq的擴展方法'使用mvc c#添加'?
「‘表’不包含‘添加’,並沒有 擴展方法‘添加’接受的第一argumnets一個認定中鍵入 「表」可以找到。(是否缺少using指令 或程序集引用?)「
我不知道爲什麼這個錯誤在這裏產生的,什麼是缺少在這裏我的代碼中的任何好友那麼請讓我知道。下面我列出了我的代碼。
這是我的dbml類表確定指標:
[global::System.Data.Linq.Mapping.TableAttribute(Name="dbo.WishList")]
public partial class WishList : INotifyPropertyChanging, INotifyPropertyChanged
{
private static PropertyChangingEventArgs emptyChangingEventArgs = new PropertyChangingEventArgs(String.Empty);
private int _Id;
private string _Laminate_Sheet_Smo;
private System.Nullable<int> _CustmorId;
public List<WishList> list { get; set; }
#region Extensibility Method Definitions
partial void OnLoaded();
partial void OnValidate(System.Data.Linq.ChangeAction action);
partial void OnCreated();
partial void OnIdChanging(int value);
partial void OnIdChanged();
partial void OnLaminate_Sheet_SmoChanging(string value);
partial void OnLaminate_Sheet_SmoChanged();
partial void OnCustmorIdChanging(System.Nullable<int> value);
partial void OnCustmorIdChanged();
#endregion
public WishList()
{
OnCreated();
}
[global::System.Data.Linq.Mapping.ColumnAttribute(Storage="_Id", AutoSync=AutoSync.OnInsert, DbType="Int NOT NULL IDENTITY", IsPrimaryKey=true, IsDbGenerated=true)]
public int Id
{
get
{
return this._Id;
}
set
{
if ((this._Id != value))
{
this.OnIdChanging(value);
this.SendPropertyChanging();
this._Id = value;
this.SendPropertyChanged("Id");
this.OnIdChanged();
}
}
}
[global::System.Data.Linq.Mapping.ColumnAttribute(Storage="_Laminate_Sheet_Smo", DbType="NVarChar(50)")]
public string Laminate_Sheet_Smo
{
get
{
return this._Laminate_Sheet_Smo;
}
set
{
if ((this._Laminate_Sheet_Smo != value))
{
this.OnLaminate_Sheet_SmoChanging(value);
this.SendPropertyChanging();
this._Laminate_Sheet_Smo = value;
this.SendPropertyChanged("Laminate_Sheet_Smo");
this.OnLaminate_Sheet_SmoChanged();
}
}
}
[global::System.Data.Linq.Mapping.ColumnAttribute(Storage="_CustmorId", DbType="Int")]
public System.Nullable<int> CustmorId
{
get
{
return this._CustmorId;
}
set
{
if ((this._CustmorId != value))
{
this.OnCustmorIdChanging(value);
this.SendPropertyChanging();
this._CustmorId = value;
this.SendPropertyChanged("CustmorId");
this.OnCustmorIdChanged();
}
}
}
public event PropertyChangingEventHandler PropertyChanging;
public event PropertyChangedEventHandler PropertyChanged;
protected virtual void SendPropertyChanging()
{
if ((this.PropertyChanging != null))
{
this.PropertyChanging(this, emptyChangingEventArgs);
}
}
protected virtual void SendPropertyChanged(String propertyName)
{
if ((this.PropertyChanged != null))
{
this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
}
}
}
這是一流的,我有使自定義的也是我的模型文件夾:
public class WishListCs
{
[Key]
public int id { get; set; }
public string Laminate_Sheet_Smo { get; set; }
public int CustmorId { get; set; }
}
這是我的控制器代碼:
DataClasses1DataContext db = new DataClasses1DataContext();
if (!string.IsNullOrEmpty(CookieHelper.GetCookieValue(CookieKeys.WishLaminateId)))
{
string pids = CookieHelper.GetCookieValue(CookieKeys.WishLaminateId);
var v = pids.Split(',');
var length = v.Length;
for (int i = 0; i < length; i++)
{
WishList addtbl = new WishList();
addtbl.Laminate_Sheet_Smo = v[i];
addtbl.CustmorId = Convert.ToInt32(CookieHelper.GetCookieValue(CookieKeys.CustId));
db.WishLists.Add() // here i am getting error
int UserId = Convert.ToInt32(CookieHelper.GetCookieValue(CookieKeys.CustId));
var h = db.WishLists.Where(x => x.CustmorId == UserId).Count();
CookieHelper.SetCookie(CookieKeys.CountOfCart, h.ToString());
}
}
這是我的代碼請任何一位幫助我如何解決這個錯誤。
@大衛布朗你有想法如何解決這個錯誤? – coder
我認爲它應該是'db.WishLists.Add(addtbl)'而不是'db.WishLists.Add()' –
