作爲一個免責聲明,我會說我仍然試圖圍繞整個DI模式進行包裝,因此我猜想不必說我的代碼可能會有一個重大的概念錯誤。使用Ninject進行多重依賴注入的問題
就這樣,我想要做的是對下列實施注入兩個屬性:
interface ISurface
{
string Use();
}
class Canvas : ISurface
{
public string Use()
{
return "canvas";
}
}
class Hardboard : ISurface
{
public string Use()
{
return "hardboard";
}
}
interface IMaterial
{
string Apply(string surface);
}
class Oil : IMaterial
{
public string Apply(string surface)
{
return "painted with oil on {0}";
}
}
class Acrylic : IMaterial
{
public string Apply(string surface)
{
return "painted with acrylic on {0}";
}
}
class Artist
{
public string Name { get; set; }
[Inject]
public IMaterial Material { get; set; }
[Inject]
public ISurface Surface { get; set; }
public string Paint()
{
return Material.Apply(Surface.Use());
}
}
class PainterModule : NinjectModule
{
public override void Load()
{
Bind<ISurface>().To<Canvas>();
Bind<IMaterial>().To<Oil>();
Bind<Artist>().ToSelf();
}
}
所以,當我打電話的方法:
class Program
{
static void Main(string[] args)
{
try
{
IKernel kernel = new StandardKernel(new PainterModule());
Artist artist = kernel.Get<Artist>();
artist.Name = "Peter Gibbons";
Console.WriteLine(artist.Name + artist.Paint());
}
catch (Exception error)
{
Console.WriteLine(error.Message);
throw;
}
finally
{
Console.ReadKey(true);
}
}
}
令人驚訝的對我來說,輸出:
哇 - 我是一個白癡:)非常感謝dahlbyk! – 2010-12-05 21:10:40
