WinForm 插件系统

[英]WinForm Plugin system

原文 2010-05-29 18:49:43 2 1 c#/ .net/ wpf/ plugins

I have created ac# 2.0 WinForm application which loads dlls, searches for an interface, and then loads the interface as a plugin.我创建了 ac# 2.0 WinForm 应用程序，它加载 dll、搜索接口，然后将接口作为插件加载。 I am loading the plugins in the same appdomain as the main application because they have a GUI which I am directly loading into the application as a tab item.我在与主应用程序相同的应用程序域中加载插件，因为它们有一个 GUI，我将其作为选项卡项直接加载到应用程序中。

I would like to load them in their own app domain, but do not think it is possible because of the GUI.我想将它们加载到他们自己的应用程序域中，但由于 GUI 的原因，我认为这是不可能的。 I would also like to monitor them to tell if they are not responsive and unload them.我还想监视它们以判断它们是否没有响应并卸载它们。

Is this possible?这可能吗？ If I upgrade to WPF are things any simpler.如果我升级到 WPF，事情就简单多了。

If you allow the plugins to create their own WinForms UI controls they will have to run on the same thread as your main UI, thus you cannot isolate the plugins in their own appdomain.如果您允许插件创建自己的 WinForms UI 控件，它们将必须与您的主 UI 在同一线程上运行，因此您无法将插件隔离在它们自己的应用程序域中。

What you could do is define a non-UI abstraction layer between the host and the plugins such that plugins only message the host what type of UI they require.您可以做的是在主机和插件之间定义一个非 UI 抽象层，以便插件仅向主机发送它们需要的 UI 类型。 The host is then responsible for creating the UI controls and relay input to the plugins.然后，主机负责创建 UI 控件并将输入中继到插件。 This enables the plugin instances to live in a separate appdomain.这使插件实例能够存在于单独的应用程序域中。

Update: with WPF and System.AddIn (aka MAF) it is possible to do UI cross appdomains.更新：使用 WPF 和 System.AddIn（又名 MAF），可以跨应用程序域执行 UI。 I would read up on some opinions on MAF before going that route.在走那条路之前，我会阅读关于 MAF 的一些意见。
