动态调用 , 卸载 Assembly

1.其实还是很麻烦的. 主要是使用起来麻烦, 你不能直接在本地调用,使用Remote Type .

注意:

AppDomain 的安装是一个非常关键的部分。AssemblyProcessor 类使用 Assembly.Load() 定位程序集，它在 AppDomain 的应用程序库中寻找程序集。因此，我们需要将应用程序库设置为程序集所在的目录。这可以通过以下命令行来完成：
setup.ApplicationBase = fileInfo.DirectoryName;
还要注意86/64的问题

 class RemoteLoader : MarshalByRefObject
    {
        public RemoteLoader()
        {
           AppDomain.CurrentDomain.AssemblyResolve+=CurrentDomain_AssemblyResolve;
        }
        public void SetDomain(AppDomain arg_domain)
        {
            arg_domain.AssemblyResolve += CurrentDomain_AssemblyResolve;
        }

        Assembly CurrentDomain_AssemblyResolve(object sender, ResolveEventArgs args)
        {
            MessageBox.Show(args.Name);
            return null;
        }
        public Assembly assembly = null;
        public string FullName { get { return assembly.FullName; } }

        public void TestTypes(Func arg_fn)
        {
            var tps = assembly.GetTypes();
            foreach (var tp in tps)
            {
                if (arg_fn(tp))
                    return;
            }
        }
        public void LoadAssembly(string arg_strAssemblyFullName)
        {

                    MessageBox.Show(type.ToString());
            }
            return false;
        }        
    }

    public class LocalLoader
    {
        private AppDomain appDomain;
        private RemoteLoader remoteLoader;

            setup.CachePath = setup.ApplicationBase;
            setup.ShadowCopyFiles = "true";
            setup.ShadowCopyDirectories = setup.ApplicationBase;            

            appDomain = AppDomain.CreateDomain("TestDomain", null, setup);
            string name = Assembly.GetExecutingAssembly().GetName().FullName;
            remoteLoader = (RemoteLoader)appDomain.CreateInstanceAndUnwrap(
                name,
                typeof(RemoteLoader).FullName);

            remoteLoader.SetDomain(appDomain);
        }      

        public void LoadAssembly(string fullName)
        {
            remoteLoader.LoadAssembly(fullName);
        }

        public void Unload()
