Question

在Unity中，Web.config等效于以下C＃代码：

container
    .RegisterType<IRepositoryProvider, RepositoryProvider>(
        new PerRequestLifetimeManager(),
        new InjectionConstructor(new object[] { new RepositoryFactories() })
    );

我尝试了以下操作，但它不起作用：

<register type="Repository.Pattern.Ef6.Factories.IRepositoryProvider, Repository.Pattern.Ef6" mapTo="Repository.Pattern.Ef6.Factories.RepositoryProvider, Repository.Pattern.Ef6">
    <lifetime type="Microsoft.Practices.Unity.PerRequestLifetimeManager, Microsoft.Practices.Unity.Mvc" />
    <constructor>
        <param name="repositoryFactories" value="new object[]{new RepositoryFactories()}"/>
    </constructor>
</register>

困难的部分是如何处理＆＃34; new object [] {new RepositoryFactories（）}＆＃34;。

我认为您的配置不太合适。你需要依赖性attr。请参阅下面的示例。

Unity配置：

<unity xmlns="http://schemas.microsoft.com/practices/2010/unity">
<namespace name="ConsoleApplication8" />
<assembly name="ConsoleApplication8" />
<container name="MyContainer">
  <types>
    <type type="ConsoleApplication8.IRepositoryFactories, ConsoleApplication8"
           mapTo="ConsoleApplication8.RepositoryFactories, 
           ConsoleApplication8" />
    <type type="ConsoleApplication8.IRepositoryProvider, ConsoleApplication8"
           mapTo="ConsoleApplication8.RepositoryProvider, ConsoleApplication8"
           name="RepositoryProvider" >
      <lifetime type="singleton" />
      <constructor>
        <param name="factories">
          <dependency />
        </param>
      </constructor>
    </type>
  </types>
</container>

可能不需要完全限定名称作为程序集名称，并且命名空间已经注册。

<强>类型：

public interface IRepositoryProvider
{}

public class RepositoryProvider : IRepositoryProvider
{
    private IRepositoryFactories _factories;
    private string _name;

    public RepositoryProvider(IRepositoryFactories factories) {
        _factories = factories;
    }

    public RepositoryProvider(string name) {
        _name = name;
    }
}

public interface IRepositoryFactories { }

public class RepositoryFactories : IRepositoryFactories{}

class Program
{
    static void Main(string[] args)
    {
        IUnityContainer container = new UnityContainer();
        container.LoadConfiguration("MyContainer");

        var instance = container.
                           Resolve<IRepositoryProvider>("RepositoryProvider");
    }
}

Web.config中的Unity InjectionConstructor
