c# - Creating a List of Accessors throws an ArgumentException

Question

I get a very odd Error when creating a List of Accessors.
I have a class Component with a private List of Components. Since I want to test some of the classes behaviour regarding this list I use an Accessor of the Component-class. Also I have some dependencies in the constructor of the class I want to avoid. Therefore I manually instantiate the list in a TestInitialize()-Method

The TestInitialize()-Code looks like this:

private string _testIdentifier = "TestComponent";
private int _testConsist = 1;

private Component_Accessor _target;

[TestInitialize()]
    public void MyTestInitialize()
    {
        _target = new Component_Accessor();
        _target.Identifier = new ComponentIdentifier(_testIdentifier, _testConsist);
        _target._inputComponents = new List<Component_Accessor>();
        _target._outputComponents = new List<Component_Accessor>();
    }

The Accessor-Code looks like this:

[Shadowing("_inputComponents")]  
public List<Component_Accessor> _inputComponents { get; set; }

This compiles just fine but I get a RunTimeException:

The Object of the type "System.Collections.Generic.List'1[DT5_Training_Simulator.Model.Components.Component_Accessor]" can not be converted to the type "System.Collections.Generic.List'1[DT5_Training_Simulator.Model.Components.Component]"

Actually I'm quite at a loss here. Could anybody please tell me what I did wrong?

Shadowingテスターを混乱させるため、 public メンバーで attribute を使用しないでください。thisによると、Shadowingプライベート プロパティとメソッドをパブリックであるかのようにテストするために使用されます。プロパティは既に公開されているためShadowing、その宣言から削除する必要があります。
