作为一个免责声明,我会说我仍然试图围绕整个DI模式进行包装,因此我猜想不必说我的代码可能会有一个重大的概念错误。使用Ninject进行多重依赖注入的问题
就这样,我想要做的是对下列实施注入两个属性:
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,当我打电话的方法:
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);
}
}
}
令人惊讶的对我来说,输出:
哇 - 我是一个白痴:)非常感谢dahlbyk! – 2010-12-05 21:10:40
