控制器的ModelState与ModelStateWrappper [英] Controller ModelState with ModelStateWrappper

问题描述

HI，所有的，我是用结构图来实现依赖注入。我创建ModelStateWrapper类在服务层，它在构造函数中得到参考控制器的ModelState发送模式状态。在bootswrapper我注册了我喜欢的类型：

to all, i am use Structure Map to implement dependency-injection. I created ModelStateWrapper class to send Model state in service layer, which in constructor get reference to ModelState of controller. In bootswrapper i registered my type:

ForRequestedType<ISourceService>()
            .TheDefaultIsConcreteType<SourceService>();
ForRequestedType<IValidationDictionary>()
        .TheDefaultIsConcreteType<ModelStateWrapper>();

我怎么可以给控制器的模型状态的参考这里ModelStateWrapper？

How i can give reference of controller's model state to ModelStateWrapper here ?

P.S。对不起，我的英语：）

p.s. sorry for my english :)

推荐答案

您需要提供更多的信息，但是这是我最好的猜测，你有什么：

You need to provide more information, but this is my best guess as to what you have:

public class ModelStateWrapper : IValidationDictionary
{
    ...
     private readonly ModelState _modelState;
     public ModelStateWrapper(ModelState modelState)
     {
          _modelState = modelState;
     }
    ...
}

如果你想给一个变量（在这种情况下，控制器的模型状态）传递给ModelStateWrapper你几乎肯定需要通过调用的ObjectFactory做明确。

If you want to pass a variable (the controller's model state in this case) to the ModelStateWrapper you almost certainly need to do that explicitly by calling the ObjectFactory.

例如：

MyController : Controller 
{
   ...
   public MyAction()
   {
      ...
      IValidationDictionary validationDictionary = ObjectFactory
          .With<ModelState>(this.ModelState)
          .GetInstance<IValidationDictionary>();
      ...
   }
   ...
}
