Question

在过去的六七个月里，我一直在我的一些组件中进行DI，结果他们变得有点复杂。在过去，我一直用手写的工厂创建对象图。由于它变得无法管理，我试图将该代码移动到依赖于框架的DI（通过代码而不是某些XML文件）。我发布了我的代码以及我遇到的问题。

这是我的作文层（它很大，所以请耐心:) :)：

    IAgentFactory GetAgentFactory()
    {
        string errorMessage;
        IDictionary<AgentType, ServiceParameters> agentFactoryPrerequisite = new Dictionary<AgentType, ServiceParameters>();
        string restResponseHeaderStatus = MyConfigurationProject.GetConfigValue("RestResponseHeaderStatus", out errorMessage);


        var service1Parameters = new ServiceParameters();
        service1Parameters.BindingName = MyConfigurationProject.GetConfigValue("Service1WebHttpBindingConfiguration", out errorMessage).ToString();
        service1Parameters.HeaderPassword = MyConfigurationProject.GetConfigValue("Service1HeaderPassword", out errorMessage).ToString();
        service1Parameters.HeaderUserName = MyConfigurationProject.GetConfigValue("Service1HeaderUserName", out errorMessage).ToString();
        service1Parameters.ResponseHeaderStatus = restResponseHeaderStatus;
        service1Parameters.ServicePassword = MyConfigurationProject.GetConfigValue("Service1ServicePassword", out errorMessage).ToString();
        service1Parameters.ServiceUrl = MyConfigurationProject.GetConfigValue("Service1URL", out errorMessage).ToString();
        service1Parameters.ServiceUserName = MyConfigurationProject.GetConfigValue("Service1ServiceUserName", out errorMessage).ToString();
        agentFactoryPrerequisite.Add(new KeyValuePair<AgentType, ServiceParameters>(AgentType.Service1, service1Parameters));

        var agentFactory = new AgentFactory(agentFactoryPrerequisite);
        return agentFactory;
    }

    protected DatalayerSettings GetDataLayerSettings()
    {
        var datalayerSettings = new DatalayerSettings();
        datalayerSettings.ConnectionString = ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString;
        datalayerSettings.MySchemaName = ConfigurationManager.AppSettings["MyDatabaseSchema"];
        datalayerSettings.UpdatingUser = "Admin";
        return datalayerSettings;
    }



    PostgersDAFactory GetPostGresDaFactory()
    {
        var datalayerSettings = GetDataLayerSettings();
        return new PostgersDAFactory(datalayerSettings, "MyAssembly.PostgresDA", "MyDifferentAssembly.CommonDatalayer", "MyServiceLogPath");

            _assemblyName = assemblyName;
            _logPath = logPath;
            _commonDaAssemblyName = commonDaAssemblyName;
        }

        public IDA1 GetDA1Instance()
        {
            var type1 = Type.GetType("MyAssembly.PostgresDA.ClassRealisingImplementation_For_DA1," + _assemblyName);
            return (IDA1)Activator.CreateInstance(type1, _datalayerSettings, _logPath);
        }

        public IDA2 GetDA2Instance()
        {
            var type1 = Type.GetType("MyAssembly.PostgresDA.ClassRealisingImplementation_For_DA2," + _assemblyName);
            return (IDA2)Activator.CreateInstance(type1, _datalayerSettings);
        }

        public IDA3 GetDA3Instance()
        {
            var type1 = Type.GetType("MyAssembly2.ClassRealisingImplementation_For_DA3," + _commonDaAssemblyName);
            return (IDA3)Activator.CreateInstance(type1, _datalayerSettings);
        }

    }

在走向温莎的同时，我面临着一些问题，因为我从未使用过这个产品，但它似乎非常复杂。

的问题：

如何在参数化时将参数传递给对象构造
我知道有更好的方法来写这个“PostgersDAFactory” 上课，但根本就不知道。
有一些工厂方法，如GetAgentFactory（），它们都是依赖于其他项目的某些静态方法，而这又取决于给我配置值（我将它们存储在数据库中），另一种方法GetDataLayerSettings依赖于app config 以及一些静态字符串。
我可能会更改我的类中的参数名称提高可读性，那么如何开启Windsor的日志记录？
最后另一个复杂的方法GetFileHandler，有一些逻辑（开关盒）。

我试过去网站，但我发现消化信息非常困难，API很大，学习曲线似乎很猛。

注意：由于安全原因，我不得不更改变量名称。
