3.经典方式下的注入实现

    在完成了Assembler这个基础环境后，就是怎么注入的问题了，下面是对三种方式的经典方法实现：

    3.1 Constructor Injection方式

Unit Test - Constructor
using Microsoft.VisualStudio.TestTools.UnitTesting;
using VisionLogic.Training.DependencyInjection.Scenario;
namespace VisionLogic.Training.DependencyInjection.Scenario.UnitTest
{
[TestClass]
public class ConstructorInjectionTest
{
class Client
{
private IWeatherReader reader;
public Client(IWeatherReader reader)
{
this.reader = reader;
}
}

[TestMethod]
public void Test()
{
IWeatherReader reader = new Assembler<IWeatherReader>().Create();
Client client = new Client(reader);
Assert.IsNotNull(client);
}
}
}

    3.2 Setter Injection方式

Unit Test - Setter
using Microsoft.VisualStudio.TestTools.UnitTesting;
using VisionLogic.Training.DependencyInjection.Scenario;
namespace VisionLogic.Training.DependencyInjection.Scenario.UnitTest
{
[TestClass]
public class SetterInjectionTest
{
class Client
{
private IWeatherReader reader;
public IWeatherReader Reader
{
get { return reader; }
set { reader = value; }
}
}

[TestMethod]
public void Test()
{
IWeatherReader reader = new Assembler<IWeatherReader>().Create();
Client client = new Client();
client.Reader = reader;
Assert.IsNotNull(client.Reader);
}
}
}

    3.3 Interface Injection方式

Unit Test - Interface
using Microsoft.VisualStudio.TestTools.UnitTesting;
using VisionLogic.Training.DependencyInjection.Scenario;
namespace VisionLogic.Training.DependencyInjection.Scenario.UnitTest
{
[TestClass]
public class InterfaceInjectionTest
{
interface IClientWithWeatherReader
{
IWeatherReader Reader { get; set;}
}

class Client : IClientWithWeatherReader
{
private IWeatherReader reader;

#region IClientWithWeatherReader Members
public IWeatherReader Reader
{
get { return reader; }
set { reader = value; }
}
#endregion
}

[TestMethod]
public void Test()
{
IWeatherReader reader = new Assembler<IWeatherReader>().Create();
Client client = new Client();
IClientWithWeatherReader clientWithReader = client;
clientWithReader.Reader = reader;
Assert.IsNotNull(clientWithReader.Reader);
}
}
}
