光脚丫学LINQ(042)：如何将列表示为由数据库生成的列

[Column(Storage="_OrderID",
    AutoSync=AutoSync.OnInsert,
    DbType="Int NOT NULL IDENTITY",
    IsPrimaryKey=true,
    IsDbGenerated=true)]
public int OrderID
{
 get
 {
  return this._OrderID;
 }
 set
 {
  if ((this._OrderID != value))
  {
   this.OnOrderIDChanging(value);
   this.SendPropertyChanging();
   this._OrderID = value;
   this.SendPropertyChanged("OrderID");
   this.OnOrderIDChanged();
  }
 }
}
