painboyCoder，

Hi painoboyCoder,

谢谢您在这里发布.

>>在"Color.ColorManager"类型上未找到导入构造函数.

>>No importing constructor was found on type 'Color.ColorManager'.

您要导入以下内容吗?

如果是，请添加参考System.ComponentModel.Composition.

If it is, please add reference System.ComponentModel.Composition. 

对于您的代码，请将私有更改为公开.

And for your code, please change private to public.

namespace Color.ColorManager
{

    public class ColorManager : IColorManager, IPlugin
    {

私有IColorManager _ColorManagers; 公共 ColorManager(IEnumerable< IColorManager> colorManagers) { this.ColorManagers = colorManagers; } } }

private IColorManager _ColorManagers; public ColorManager(IEnumerable<IColorManager> colorManagers) { this.ColorManagers = colorManagers; } } }

我希望这会对您有所帮助.

I hope this would be helpful to you.
