首先这种情况出现在应用程序启动前的方法里面。

本想通过发射来实现一些功能。谁知道被这个坑了。

碰到这种问题。已经相当无语了。同时也不知道该如何解决。望有能之士帮忙解答

using System;using System.IO;using System.Linq;using System.Reflection;using System.Web;using System.Web.Compilation;using System.Web.Hosting;using Infrastructure;[assembly: PreApplicationStartMethod(typeof(PreApplicationInit), "InitializePlugins")]namespace Infrastructure{    public class PreApplicationInit    {        static PreApplicationInit()        {            var pluginsPath = HostingEnvironment.MapPath("~/plugins");                        var pluginsTempPath = HostingEnvironment.MapPath("~/plugins/temp");            if (pluginsPath == null || pluginsTempPath == null)	            throw new DirectoryNotFoundException("plugins");            PluginFolder = new DirectoryInfo(pluginsPath);            TempPluginFolder = new DirectoryInfo(pluginsTempPath);        }        /// 
        /// The source plugin folder from which to copy from        /// 
        /// 
     
              /// This folder can contain sub folders to organize plugin types        /// 
             private static readonly DirectoryInfo PluginFolder;        /// 
        /// The folder to  copy the plugin DLLs to use for running the app        /// 
        private static readonly DirectoryInfo TempPluginFolder;        /// 
        /// Initialize method that registers all plugins        /// 
        public static void InitializePlugins()        {            var assemblies = PluginFolder.GetFiles("*.dll", SearchOption.AllDirectories)                    .Select(x => Assembly.LoadFrom(x.FullName));            foreach (var assembly in assemblies)            {                var type = assembly.GetTypes().FirstOrDefault(t => t.GetInterface(typeof(IModule).Name) != null);                if (type == null) continue;                //Add the plugin as a reference to the application                if (AppDomain.CurrentDomain.GetAssemblies().All(a => a.FullName != assembly.FullName))                {                    BuildManager.AddReferencedAssembly(assembly);                }                //Add the modules to the PluginManager to manage them later                var module = (IModule)Activator.CreateInstance(type);                PluginManager.Current.Modules.Add(module, assembly);            }        }    }}

　　上面是代码。

如果通过Type.IsAssignableFrom方法来查找接口的实现，根本查不到。

 

这是目录结构

这是Module的实现

using System;using Infrastructure;namespace NewsPlugin{    public class Module:IModule    {        public string Name {            get            {                return "NewsPlugin";            }            set            {                if (value == null) throw new ArgumentNullException("value");                this.Name = value;            }        }    }}
