Question

我收到了错误

The type GenericObject<ISomeInterface> must be convertible to <GenericObject<GenericObject<ISomeInterface>> 
in order to use it as parameter <T> in the generic class Wrapper<T>

有问题的课程

public abstract class GenericObject<T> : ReactiveObject where T: class, ISomeInterface

public class SpecificSubObject: GenericObject<SpecificSubObject>, ISomeInterface {}

//T = any potential SpecificSubObject
public class Wrapper<T> : ReactiveObject, ISomeInterface where T : GenericObject<T>, ISomeInterface {}

//View.xaml.cs
public partial class View
{
  public Wrapper<GenericObject<ISomeInterface>> SomeWrapper {get;set;}
}

是否有某种方式（不使我的View类具有通用性（因为部分类不能通用））以使其工作？

Answer 1

您可以尝试为Wrapper添加第二个参数：

public class Wrapper<T,P> : ReactiveObject, ISomeInterface 
      where T : GenericObject<P> 
      where P : class, ISomeInterface
{...}

它应该由编译器推断，因此View将保持不变。

通用类型头痛：当通用类型从多个接口继承时，传入类型时出现问题
