Pv3-Codeplex Pv4之间的差异：
ViewPage
ViewPage类
增加了InitHelpers方法
Controller
Controller类
新实现了IAuthorizationFilter/IExceptionFilter接口
添加了 public ITempDataProvider TempDataProvider { get; set; } 属性
ControllerActionInvoker类
新增加了四个方法:
FilterInfo GetFiltersForActionMethod(MethodInfo methodInfo);
ResultExecutedContext InvokeActionResultWithFilters(ActionResult actionResult, IList<IResultFilter>
filters);
AuthorizationContext InvokeAuthorizationFilters(MethodInfo methodInfo, IList<IAuthorizationFilter>
filters);
ExceptionContext InvokeExceptionFilters(Exception exception, IList<IExceptionFilter> filters);
删除了原有的:
IList<IActionFilter> GetActionFiltersForMember(MemberInfo memberInfo);
IList<IActionFilter> GetAllActionFilters(MethodInfo methodInfo);
ResultExecutedContext InvokeActionResultWithFilters(ActionResult actionResult, IList<IActionFilter>
filters);
ControllerBuilder 类
增加了属性public HashSet<String> DefaultNamespaces { get; }
ExceptionContext类
这是一个新增加的类,我想,可以用来输出美化的异常处理,呵呵
public class ExceptionContext : ControllerContext { public ExceptionContext(ControllerContext controllerContext, Exception exception); public ActionResult Result { get; set; } public Boolean ExceptionHandled { get; set; } public Exception Exception { get; } }
属性编程与Filter中
IActionFilter接口
删除了以下两个事件
void OnResultExecuted(ResultExecutedContext filterContext);
void OnResultExecuting(ResultExecutingContext filterContext);
ActionExecutedContext类的构造函数改为
ActionExecutedContext(ControllerContext controllerContext, MethodInfo actionMethod, Boolean canceled, Exception
exception)
增加了public Boolean Canceled { get; }只读属性
ActionFilterAttribute 类
由继承于Attribute 改为继承于FilterAttribute，另外增加实现IResultFilter接口
删除了 Order 属性
另外新增加了几个类,有关用Action的Filter
public abstract class FilterAttribute : Attribute { protected FilterAttribute(); public Int32 Order { get; set; } } public class FilterInfo { public FilterInfo(); public IList<IActionFilter> ActionFilters { get; set; } public IList<IAuthorizationFilter> AuthorizationFilters { get; set; } public IList<IExceptionFilter> ExceptionFilters { get; set; } public IList<IResultFilter> ResultFilters { get; set; } } public sealed class HandleErrorAttribute : FilterAttribute, IExceptionFilter { public HandleErrorAttribute(); public String View { get; set; } public Type ExceptionType { get; set; } } public class HandleErrorInfo { public HandleErrorInfo(Exception exception, String controller, String action); public Exception Exception { get; } public String Action { get; } public String Controller { get; } } public class HttpUnauthorizedResult : ActionResult { public HttpUnauthorizedResult(); }
还有一些我看来比较有用的类
public interface IAuthorizationFilter { //用来获取用户信息的FIlter接口 void OnAuthorization(AuthorizationContext filterContext); } public interface IExceptionFilter { //用来获取异常的FIlter接口 void OnException(ExceptionContext filterContext); } public enum InsertionMode { //感觉有点像触发器的感觉 ,这个Enum所标志的那个类一定很好用呵呵 Replace, InsertBefore, InsertAfter } public interface IResultFilter { //这个应该是新的Filter接口 void OnResultExecuted(ResultExecutedContext filterContext); void OnResultExecuting(ResultExecutingContext filterContext); } public interface ITempDataProvider { TempDataDictionary LoadTempData(); void SaveTempData(TempDataDictionary tempDataDictionary); }
对于Helper中
AjaxExtensions静态类
是新增加的，代码如下：
public static class AjaxExtensions {
public static Boolean IsMvcAjaxRequest(HttpRequestBase request);
}
LinkExtensions类
Mailto方法都被删除了
AjaxHelper类
这个算是改动最大添加了一些比较有用的实现
public class AjaxHelper { public String ActionLink(String linkText, String actionName, AjaxOptions ajaxOptions); public String ActionLink(String linkText, String actionName, String controllerName, AjaxOptions ajaxOptions); public String ActionLink(String linkText, String actionName, Object values, AjaxOptions ajaxOptions); public String ActionLink(String linkText, String actionName, RouteValueDictionary values, AjaxOptions ajaxOptions); public String ActionLink(String linkText, String actionName, String controllerName, RouteValueDictionary values, AjaxOptions ajaxOptions); public String ActionLink(String linkText, String actionName, Object values, AjaxOptions ajaxOptions, Object htmlAttributes); public String ActionLink(String linkText, String actionName, RouteValueDictionary values, AjaxOptions ajaxOptions, IDictionary<String,Object> htmlAttributes); public String ActionLink(String linkText, String actionName, String controllerName, Object values, AjaxOptions ajaxOptions); public String ActionLink(String linkText, String actionName, String controllerName, RouteValueDictionary values, AjaxOptions ajaxOptions, IDictionary<String,Object> htmlAttributes); public String ActionLink(String linkText, String actionName, String controllerName, Object values, AjaxOptions ajaxOptions, Object htmlAttributes); public IDisposable Form(String actionName, AjaxOptions ajaxOptions); public IDisposable Form(String actionName, Object values, AjaxOptions ajaxOptions); public IDisposable Form(String actionName, RouteValueDictionary values, AjaxOptions ajaxOptions); public IDisposable Form(String actionName, String controllerName, AjaxOptions ajaxOptions); public IDisposable Form(String actionName, String controllerName, RouteValueDictionary values, AjaxOptions ajaxOptions); public IDisposable Form(String actionName, Object values, AjaxOptions ajaxOptions, Object htmlAttributes); public IDisposable Form(String actionName, RouteValueDictionary values, AjaxOptions ajaxOptions, IDictionary<String,Object> htmlAttributes); public IDisposable Form(String actionName, String controllerName, Object values, AjaxOptions ajaxOptions); public IDisposable Form(String actionName, String controllerName, Object values, AjaxOptions ajaxOptions, Object htmlAttributes); public IDisposable Form(String actionName, String controllerName, RouteValueDictionary valuesDictionary, AjaxOptions ajaxOptions, IDictionary<String,Object> htmlAttributes); }
另外因此而增加了一些对AjaxHelper辅助的类
如
public class AjaxOptions { public AjaxOptions(); public InsertionMode InsertionMode { get; set; } public String OnBegin { get; set; } public String OnFailure { get; set; } public String OnSuccess { get; set; } public String UpdateTargetId { get; set; } }
存储系统
TempDataDictionary 类
设置为可以序列化
添加了Load和Save方法,并给了一个可以反序列化初始化的构造函数
ViewDataDictionary类
增加了个public Object Eval(String expression); 方法
MemberShip
对于微软自己的角色控制，有２个类被添加
public class AuthorizationContext : ControllerContext { //看来是用来在Membership得到Action信息 public AuthorizationContext(ControllerContext controllerContext, MethodInfo actionMethod); public ActionResult Result { get; set; } public Boolean Cancel { get; set; } public MethodInfo ActionMethod { get; } } public sealed class AuthorizeAttribute : FilterAttribute, IAuthorizationFilter { //这个是在Controller中获取用户信息的应该是的,呵呵 public AuthorizeAttribute(); public String Roles { get; set; } public String Users { get; set; } }
新功能
MVC的缓存
public class MvcHttpHandler : UrlRoutingHandler, IRequiresSessionState { public MvcHttpHandler(); } public sealed class OutputCacheAttribute : ActionFilterAttribute, IActionFilter, IResultFilter { //明显就是一个缓存的Filter呵呵 public OutputCacheAttribute(); public Boolean NoStore { get; set; } public Int32 Duration { get; set; } public OutputCacheLocation Location { get; set; } public String CacheProfile { get; set; } public String VaryByContentEncoding { get; set; } public String VaryByCustom { get; set; } public String VaryByHeader { get; set; } public String VaryByParam { get; set; } }
删除 的类
public static class ButtonBuilder; // removed
public static class ButtonsAndLinkExtensions; // removed
public class ComponentController; // removed
public static class ImageBuilder; // removed
public static class ImageExtensions; // removed
public static class ViewExtensions; // removed
