MVC Exception Handling

Log exception information using Nlog

First refer to the Nlog DLL file, modify the configuration file, under configuration under the Configsections node, configure the Nlog associated configuration section for example < Name= "Nlog" type= "NLog.Config.ConfigSectionHandler, nlog" /> , Configure the Nlog log output path configuration under the configuration node

<Nlogxmlns= "Http://www.nlog-project.org/schemas/NLog.xsd"Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance">    <Targets>      <Targetname= "FileLog"type= "File"FileName= "${basedir}/log/${shortdate}/${level}.txt"Layout= "" ${date:format=yyyy-mm-dd hh\:mm\:ss} "" ${level} "${message} ${exception}" />    </Targets>    <rules>      <Loggername="*"MinLevel= "Debug"WriteTo= "FileLog" />    </rules>  </Nlog>

Create a new property that inherits from Handleerrorattribute, which handles exceptions with the following code

 Public classCustomerexceptionattribute:handleerrorattribute {/// <summary>        ///Exception Handling/// </summary>        /// <param name= "Filtercontext" ></param>         Public Override voidonexception (Exceptioncontext filtercontext) {NLog.LogManager.GetCurrentClassLogger ().            Error (filtercontext.exception); Base.            Onexception (Filtercontext); FilterContext.HttpContext.Response.Redirect (""); }     }

Add the attribute where you want to handle the exception

        [customerexception]        public  actionresult Index ()        {            int0 ;             int 3 / A;             return View ();        }
