一个HttpHandler的小设计
例子
class Program { static void Main() { Son s = new Son(); s.show(); Console.Read(); } } abstract class Father { public void show() { doMethod(); } protected abstract void doMethod(); } class Son:Father { protected override void doMethod() { Console.WriteLine("Son Do Something"); } }
扩展
namespace Test { class Program { static void Main() { IHttpHandler person = HttpHandlerFactory.CreateIHttpHandler("Handler"); person.ProcessRequest(); Console.Read(); } } public interface IHttpHandler { void ProcessRequest(); } public class HttpHandlerFactory { public static IHttpHandler CreateIHttpHandler(string type) { Assembly ass = Assembly.Load("Test"); Type t = ass.GetType("Test." + type); object instance = Activator.CreateInstance(t, true); return instance as IHttpHandler; } } public abstract class HandlerBase : IHttpHandler { public void ProcessRequest() { doMethod(); } protected abstract void doMethod(); } class Handler : HandlerBase { protected override void doMethod() { Console.WriteLine("Son Do Something"); } } }
再扩展
namespace Test { public class Context { public static string Controller = "Handler"; public static string Action = ""; } class Program { static void Main() { HttpHandlerFactory f = new HttpHandlerFactory(); Console.Read(); } } public interface IHttpHandler { void ProcessRequest(); } public class HttpHandlerFactory { public HttpHandlerFactory() { IHttpHandler page = HttpHandlerFactory.CreateIHttpHandler(Context.Controller); page.ProcessRequest(); } public static IHttpHandler CreateIHttpHandler(string type) { Assembly ass = Assembly.Load("Test"); Type t = ass.GetType("Test." + type); object instance = Activator.CreateInstance(t, true); return instance as IHttpHandler; } } public abstract class HandlerBase : IHttpHandler { public void ProcessRequest() { doMethod(); } protected abstract void doMethod(); } class Handler : HandlerBase { protected override void doMethod() { Console.WriteLine("Son Do Something"); } } }
上面就是模拟一般处理程序的流程,一般没有HandlerBase,
不晓得MVC是不是这样设计的
namespace Test { public class Context { public static string NameSpace = "Test"; public static string Controller = "Handler"; public static string Action = "Show"; public static object[] parameters = new object[] { "hongda", 5 }; } class Program { static void Main() { Assembly ass = Assembly.Load(Context.NameSpace); Type t = ass.GetType(Context.NameSpace + "." + Context.Controller); object obj = ass.CreateInstance(Context.NameSpace + "." + Context.Controller); MethodInfo method = t.GetMethod(Context.Action); object result = method.Invoke(obj, Context.parameters); Console.WriteLine(result.ToString()); Console.Read(); } } public class Handler { public string Show(string a, int b) { return a + b; } } }
肯定不是,
