Ninject中的绑定 - 提供的泛型参数不等于泛型类型定义的参数？

Question

试图使用ninject将我的接口绑定到一个具体的类，但我必须失去一些东西，并不能得到它的工作。

崩溃这里

      return resolutionRoot.Resolve(request).SingleOrDefault();

      if (!Errors.ContainsKey(key)) 
      {

      }   
     } 

     public bool IsValid() 
     { 
      if (Errors.Count > 0) 
      { 
       return false; 
      } 

      return true; 
     } 

     public Dictionary<string, string> Errors { get; private set; } 
     public T Response { get; set; } 

     public ResponseBase Status { get; set; } 
    } 


Bind(typeof(IResponseResult)).To(typeof(ResponseResult<>));

你没有真正提供该服务的 '构造泛型类型'。
Generics -Open and closed constructed Types
What exactly is an "open generic type" in .NET?

Ninject里面居然试图使一个 - 但预计generic arguments，你没有。

Type.MakeGenericType(service.GetGenericArguments()) 

我不确定你在想什么 - 以及如何解决这样的问题。

你可以尝试ToProvider或设置提供商 - 但你仍然错过了一些东西。
