我正在使用Entity Framework 6(Model First)。所以我有幾個類是由model.tt生成的。這是我的汽車類:將PropertyChanged.Fody添加到Entity Framework Model.tt

namespace MyNamespace
{
using System;
using System.Collections.Generic;
public partial class Car
{
public Car()
{
this.Wheels = new HashSet<Wheel>();
}
public int CarId { get; set; }
public string Make { get; set; }
public string Model { get; set; }
public string Year { get; set; }
public string VIN { get; set; }
public virtual ICollection<Wheel> Wheels { get; set; }
}
}
我也在我的項目中的其他類上使用PropertyChanged.Fody。我有幾個類,但只是從我生成的類包裝性能,像這樣的屬性:
using System;
using PropertyChanged;
namespace MyNamespace
{
[ImplementPropertyChanged]
public class CarWrapper
{
public CarWrapper(Car car)
{
Car = car;
}
public Car car { get; set; }
public string Make
{
get { return Car.Make; }
set { Car.Make = value; }
}
public string Model
{
get { return Car.Model; }
set { Car.Model = value; }
}
public string Year
{
get { return Car.Year; }
set { Car.Year = value; }
}
public string VIN
{
get { return Car.VIN; }
set { Car.VIN = value; }
}
}
}
所以,ProperyChanged.Fody會做它的魔力在我車內財物,而不是其他人,但如果我是編輯我的Model.tt並添加[ImplementPropertyChanged]
屬性,我生成的類將全部通知屬性更改。然後,我可以修改車內財物的CarWrapper像這樣:
[AlsoNotifyFor("Make")]
[AlsoNotifyFor("Model")]
[AlsoNotifyFor("Year")]
[AlsoNotifyFor("VIN")]
public Car car { get; set; }
這將是在所有的,如果我要得到通知的內車內財物的變化做一件好事嗎?它會是多餘的嗎?還有其他建議嗎?
