MVC TIP4：为捕获路由及通用异常处理

对于未路由到的URL，可以如下处理。

1：首先，准备控制器

public  class  ErrorController : Controller {      public  ActionResult Index( string  error)      {          ViewData[ "Title" ] = "WebSite 网站内部错误" ;          ViewData[ "Description" ] = error;          return  View( "Index" );   //全部路由到Error下的Index视图      }      public  ActionResult HttpError404( string  error)      {          ViewData[ "Title" ] = "HTTP 404- 无法找到文件" ;          ViewData[ "Description" ] = error;          return  View( "Index" );      }      public  ActionResult HttpError500( string  error)      {          ViewData[ "Title" ] = "HTTP 500 - 内部服务器错误" ;          ViewData[ "Description" ] = error;          return  View( "Index" );      }      public  ActionResult General( string  error)      {          ViewData[ "Title" ] = "HTTP 发生错误" ;          ViewData[ "Description" ] = error;          return  View( "Index" );      }  }

2：Error下的Index视图

代码：

3：在Global.aspx中进行处理

添加如下方法：

protected  void  Application_Error( object  sender, EventArgs e) {      Response.Clear();      Exception exception = Server.GetLastError();      HttpException httpException = exception as  HttpException;      RouteData routeData = new  RouteData();      routeData.Values.Add( "controller" , "Error" );      if  (exception == null )      {          routeData.Values.Add( "action" , "Index" );      }      else  if  (httpException == null )      {          routeData.Values.Add( "action" , "Index" );      }      else      {          switch  (httpException.GetHttpCode())          {              case  404:                  routeData.Values.Add( "action" , "HttpError404" );                  break ;              case  500:                  routeData.Values.Add( "action" , "HttpError500" );                  break ;              default :                  routeData.Values.Add( "action" , "General" );                  break ;          }      }      // Pass exception details to the target error View.       routeData.Values.Add( "error" , exception.Message);      // Clear the error on server.       Server.ClearError();      // Call target Controller and pass the routeData.       IController errorController = new  ErrorController();      errorController.Execute( new  RequestContext( new  HttpContextWrapper(Context), routeData)); } 本文转自最课程陆敏技博客园博客，原文链接：http://www.cnblogs.com/luminji/archive/2011/07/31/2122533.html，如需转载请自行联系原作者
