asp.net-mvc-3 – 具有ASP.NET MVC3和嵌入式Razor视图的插件框架

首先我用PreApplicationStartMethod创建一个类.此方法扫描插件文件夹,并将dll复制到AppDomain.DynamicDirectory.

然后使用BuildManager.AddReferencedAssembly加载这些dll的每个.

而且,强大的剃刀视图编译精美.请看代码：

[assembly: PreApplicationStartMethod(typeof(MySolution.PluginHandler.PluginActivator),"Initialize")]
namespace MySolution.PluginHandler
{
    public class PluginActivator
    {
        private static readonly DirectoryInfo PluginFolderInfo;

        static PluginActivator() {
            PluginFolderInfo = new DirectoryInfo(HostingEnvironment.MapPath("~/plugins"));
        }

        public static void Initialize() {
            CopyPluginDlls(PluginFolderInfo,AppDomain.CurrentDomain.DynamicDirectory);
            LoadPluginAssemblies(AppDomain.CurrentDomain.DynamicDirectory);
        }

        private static void CopyPluginDlls(DirectoryInfo sourceFolder,string destinationFolder)
        {
            foreach (var plug in sourceFolder.GetFiles("*.dll",SearchOption.AllDirectories)) {
                if (!File.Exists(Path.Combine(destinationFolder,plug.Name))) {
                    File.Copy(plug.FullName,Path.Combine(destinationFolder,plug.Name),false);
                }
            }
        }

        private static void LoadPluginAssemblies(string dynamicDirectory)
        {
            foreach (var plug in Directory.GetFiles(dynamicDirectory,"*.dll",SearchOption.AllDirectories)) {
                Assembly assembly = Assembly.Load(AssemblyName.GetAssemblyName(plug));
                BuildManager.AddReferencedAssembly(assembly);
            }
        }
    }
}

我希望这可以帮助其他想要使用这些新技术创建一个干净的插件框架的程序员.
