我正在用C#编写一个Addin框架,我想知道如何在不需要重新启动应用程序的情况下使Addin无法加载.
我听说过AppDomains但这些有用吗？ Addin可以添加可扩展性类,并且可以通过接口在主AppDomain中调用,并且仍然可以卸载并调用清理代码,导致这些类被删除而该程序集不在主AppDomain中吗？
或者是否有其他方法可以实现无法加载的插件,但是除了AppDomain之外的IIRC,你无法卸载组件.
如果可能的话,我还希望插件引擎与Mono兼容,所以如果可以的话,任何答案都会尝试与Mono保持兼容.
解决方法
你可能想看看
Mono.Addins.有一些好看的样品
here,这里有一些细节：
The following code is a basic example of an add-in host application.
This application runs a set of commands which can be implemented by
add-ins:
using System;
using Mono.Addins;
[assembly:AddinRoot ("HelloWorld","1.0")]
class MainClass
{
public static void Main ()
{
AddinManager.Initialize ();
AddinManager.Registry.Update ();
foreach (ICommand cmd in AddinManager.GetExtensionObjects<ICommand> ())
cmd.Run ();
}
}
The extension point for the above example can be declared like this:
using Mono.Addins;
[TypeExtensionPoint]
public interface ICommand
{
void Run ();
}
An add-in extending the above extension point would look like this:
using System;
using Mono.Addins;
[assembly:Addin]
[assembly:AddinDependency ("HelloWorld","1.0")]
[Extension]
public class HelloCommand: ICommand
{
public void Run ()
{
Console.WriteLine ("Hello World!");
}
}
