MVC继承Controller类并重写OnException方法实现全局错误日志

1）创建类BaseController.cs ，继承Controller类并重写OnException方法，代码如下

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

namespace WebApplication70.Controllers
{
public class BaseController : Controller
{
protected override void OnException(ExceptionContext filterContext)
{
// 错误日志编写
string controllerNamer = filterContext.RouteData.Values["controller"].ToString();
string actionName = filterContext.RouteData.Values["action"].ToString();
string exception = filterContext.Exception.ToString();
// 执行基类中的OnException
base.OnException(filterContext);
}
}
}
2）然后其他需要记录日志的Controller继承BaseController即可

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

namespace WebApplication70.Controllers
{
public class HomeController : BaseController
{
public ActionResult Index()
{
string test1 = "a";
int test2 = Int32.Parse(test1);
return View();
}
}
}
