MVC 2中HandleErrorFilter的问题及其解决方法

近日在使用MVC2的异常处理的时候，遇到一些问题
1. 我们的Error.aspx是没有使用MasterPage
2.通过如下代码测试

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace MvcApplication1.Controllers
{
[HandleError]
public class HomeController : Controller
{
public ActionResult Index()
{
throw new ApplicationException();

}

public ActionResult About()
{
return View();
}

public ActionResult Test()
{
return View("Error");
}
}
}

.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }

 

我们发现会遇到500错误





通过工具，我看到下面代码





其实要讲起来，应该后面三句代码是多余的

【备注】如果Error.aspx是有MasterPage的时候，又不会出错，这倒是很奇怪的。

 

这样的话，其实我们可以定义一个自己的Handler，下面这个例子，我只是把Master的属性和后面三行删除掉了。这样问题就解决了，不管有没有MasterPage，也不管是什么异常都能被Handle了

 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace MvcApplication1
{
public class MyErrorHandler:ActionFilterAttribute,IExceptionFilter
{
public MyErrorHandler()
{
View = "Error";
}
public void OnException(ExceptionContext filterContext)
{
string controllerName = (string)filterContext.RouteData.Values["controller"];
string actionName = (string)filterContext.RouteData.Values["action"];
HandleErrorInfo model = new HandleErrorInfo(filterContext.Exception, controllerName, actionName);
ViewResult result = new ViewResult();
result.ViewName = this.View;
result.ViewData = new ViewDataDictionary(model);
result.TempData = filterContext.Controller.TempData;
filterContext.Result = result;
filterContext.ExceptionHandled = true;

}

public string View { get; set; }
}
}

.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }
