System.Web.Mvc.HandleErrorInfo错误的模型类型

问题描述：

我创建了正确的模型类型，并不明白它来自何处。有任何想法吗？这里System.Web.Mvc.HandleErrorInfo错误的模型类型

 
public class ExtendendHandleErrorAttribute : HandleErrorAttribute 
    { 
     public override void OnException(ExceptionContext filterContext) 
     {         
      LogErrors(filterContext); 
      try 
      { 
       base.OnException(filterContext); 

       var typedResult = filterContext.Result as ViewResult; 
       if (typedResult != null) 
       { 
        var tmpModel = typedResult.ViewData.Model; 
        typedResult.ViewData = filterContext.Controller.ViewData; 
        typedResult.ViewData.Model = CreateModel(filterContext); 
        filterContext.Result = typedResult; 
       } 
      } 
      catch(Exception ex) 
      { 
       new LogManager().Log("ExtendendHandleErrorAttribute error", ex); 
      } 
     }

有趣的是，我创建ErrorCodeModel：

 
System.InvalidOperationException: The model item passed into the dictionary is of type 'System.Web.Mvc.HandleErrorInfo', 
but this dictionary requires a model item of type 'BusinessLogic.Models.ErrorCodeModel'. 
    at System.Web.Mvc.ViewDataDictionary`1.SetModel(Object value) 
    at System.Web.Mvc.ViewDataDictionary..ctor(ViewDataDictionary dictionary) 
    at System.Web.Mvc.WebViewPage`1.SetViewData(ViewDataDictionary viewData) 
    at System.Web.Mvc.RazorView.RenderView(ViewContext viewContext, TextWriter writer, Object instance) 
    at System.Web.Mvc.ViewResultBase.ExecuteResult(ControllerContext context) 
    at System.Web.Mvc.ControllerActionInvoker.InvokeAction(ControllerContext controllerContext, String actionName) 
    at System.Web.Mvc.Controller.ExecuteCore() 
    at System.Web.Mvc.ControllerBase.Execute(RequestContext requestContext) 
    at System.Web.Mvc.MvcHandler.c__DisplayClass6.c__DisplayClassb.b__5() 
    at System.Web.Mvc.Async.AsyncResultWrapper.c__DisplayClass1.b__0() 
    at System.Web.Mvc.MvcHandler.c__DisplayClasse.b__d() 
    at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() 
    at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

中的global.asax.cs

我注册一个自定义属性：

 
     public static void RegisterGlobalFilters(GlobalFilterCollection filters) 
     { 
      filters.Add(new Controllers.ExtendendHandleErrorAttribute()); 
     }

的定义是这样的。

 
     private ErrorCodeModel CreateModel(ExceptionContext filterContext) 
     { 
      var model = new ErrorCodeModel(); 

      if (filterContext.HttpContext.Session != null) 
      { 
       var session = filterContext.HttpContext.Session; 

       model.SessionId = session.SessionID; 
       StateHandler stateHandler = new StateHandler(session); 
       model.FapiErrorCode = stateHandler.CustomErrorCode.ToString();    
       try 
       {      
        model.GlobalData = new GlobalDataBuilder(stateHandler).Build(); 
        model.ErrorMessage = model.GlobalData.ErrorText.TechnicalError; 
       } 
       catch { } 
      } 

      return model; 
     }

我的web.config

 
<customErrors mode="Off" defaultRedirect="Error"> 
     <error statusCode="404" redirect="Error/FileNotFound" /> 
    </customErrors>

你能解释bri呃，你的情景，你试图达到什么目的，你为了达到目标而做了什么，什么不起作用？那么，最后一部分你已经显示了错误信息。 – 2011-04-21 09:31:32

在~/Views/Shared/Error.cshtml替换第一行：

@model System.Web.Mvc.HandleErrorInfo

与

@model BusinessLogic.Models.ErrorCodeModel

它已经使用@model BusinessLogic.Models.ErrorCodeModel – NickD 2011-04-21 14:22:46

我的Error.cshtml中有一个自定义@model，我仍然得到错误。任何其他想法？ – 2012-04-26 20:03:48

答

当你使用一个控制器或行动上[HandleError]属性，抛出的异常，通过你的web.config描述将导致重定向到自定义错误页。默认情况下，错误使用HandleErrorInfo模型转到~\Views\Shared\Error.cshtml。

的web.config部分，可以是这样的：

<system.web> 
    <customErrors mode="On" defaultRedirect="Error.aspx"> 
    <error statusCode="403" redirect="NoAccess.htm"/> 
    <error statusCode="404" redirect="FileNotFound.htm"/> 
    </customErrors> 
</system.web>

是的，这是正确的。请阅读我的更新说明。 – NickD 2011-04-21 10:12:43
