Question

我想编译一个DLL控件，是一个扩展面板，但我只有类，我不喜欢使用类添加自定义控件，我更喜欢将DLL添加到工具箱中。

有人可以帮我将其转换为类库DLL控件吗？

PS：另外也许我可能需要一个指导步骤来制作类库，这是我第一次尝试这个。

我一直只使用CustomControlLibrary命名它并将程序集名称和默认命名空间设置为您想要的dll，然后右键单击项目并选择添加类，然后您将添加自定义控件的类代码到项目。您还可以在此时添加新的UserControl。编译时，它会创建一个dll，您可以通过右键单击ToolBox选择选择项目然后浏览到您创建的Dll来浏览。然后，它会将控件库中包含的控件添加到ToolBox中。
