将Combobox绑定到使用MEF继承接口的类（Managed extensibility framework .. [英] Bind Combobox with classes who inherit interface using MEF(Managed extensibility framework ..

问题描述

请遵守代码流程。

我有一个接口Ishape，它在一些独立的dll或类库中。

Please under stand the flow of code .
I have an interface Ishape which in some separate dll or class library.

[InheritedExport]
    public interface Ishape
    {

        int Paint(int width, int height);

    }

在我的窗口应用程序中，我有两节课。

In my window application I have two classes.

public class Circle : MEF_Test.Ishape
   {
       public int Paint(int width, int height)
       {

           return 0;
       }

   }
   [Export(typeof(Ishape))]
   public class Rect : MEF_Test.Ishape
   {
       public int Paint(int width, int height)
       {

           return 0;
       }

   }

我想要绑定类继承接口IShape的组合框中的名称。

我是窗口应用程序和MEF（托管扩展框架）的新手



请有人帮忙。我需要尽快。

推荐答案

只需使用元数据，例如：



[ExportMetadata（Name，ControlsLibrary1.BlueControl） ]



然后当你加载所有形状时，你可以将它们添加到组合框。

我希望它可以帮到你：）

Hi,

Just use the meta data for example:

[ExportMetadata("Name", "ControlsLibrary1.BlueControl")]

Then when you load all of the Shapes you can add them to the Combo-Box.

I hope it would help you :)
