C# generics propertygrid collectioneditor

带有 GenericItems 的 PropertyGrid GenericList

有没有一种方法可以显示和编辑从抽象泛型类派生的对象的 PropertyGrid （及其 CollectionEditor）中的值？我没有只显示类似这样的属性：“IFilter´1”或“BaseFilter'1”其中 IFilter 是一个接口，而 BaseFilter 是一个抽象类。

此列表包含的所有对象：

List<IFilter<bool>> _activeFilter = new List<IFilter<bool>>();

有一个抽象类，实现 IFilter：

public abstract class FilterBase<T> : IFilter<T> { ... }

以及 FilterBase 的一些专门实现

    public class SimpleBool : FilterBase<bool> {

    public bool BoolValue { get; set; }

    protected override bool Process(bool input) {
        return input && BoolValue;
    }
}

当我将这样一个“SimpleBool”类添加到上面定义的列表中时，PropertyGrid 将不会显示任何属性。但当我定义具有非泛型类型的泛型列表时，它显示一切正确。

有解决方案来完成这项工作吗？我尝试添加一些 TypeConverter 和自己的 CollectionEditor。显然没有运气=(

原文

Is there a way to display and edit values in the PropertyGrid (and his CollectionEditor) of an object, which is derived from an abstract generic class?
I don't get the properties displayed only something like this: "IFilter´1" or "BaseFilter'1" Where IFilter is an Interface, and BaseFilter an abstract class.

All objects contained by this list:

List<IFilter<bool>> _activeFilter = new List<IFilter<bool>>();

There is one abstract class, implementing the IFilter:

public abstract class FilterBase<T> : IFilter<T> { ... }

And a few specialized implementations of the FilterBase

    public class SimpleBool : FilterBase<bool> {

    public bool BoolValue { get; set; }

    protected override bool Process(bool input) {
        return input && BoolValue;
    }
}

When I add such a "SimpleBool" class to the above defined list, the PropertyGrid wont display any of the Properties. But it displays all correct when I define an Generic List with a non generic Type.

Is there an Solution to get this work? I tryed to add some TypeConverter and an own CollectionEditor. Obviously without luck =(
