MVC 5 c＃将错误报告回数据库

Question

we have an MVC application , what is the best way to record errors generated (by users) back to our support database? users should only see "this error has been reported" error message

all the details should be written to to a database

please help!

Answer 1

I suggest you either make use of External library like Log4Net or create you own library class which will do logging for you.

One more suggestion is make use of ExceptionFilter which is avaiable in MVC file and write code of logging in that filter. I am suggesting becuase it will not cause you to write code again and again it follows DRY principle.

Example :

public class CustomExceptionFilter: FilterAttribute,  
IExceptionFilter   
{  
    public void OnException(ExceptionContext filterContext)   
    {  
        if (!filterContext.ExceptionHandled)   
        {  
            //log error here 
            Logger.LogException(filterContext.Exception);
            //this will redirect to error page and show use logging is done 
            filterContext.Result = new   
                        RedirectResult("customErrorPage.html");  
             filterContext.ExceptionHandled = true;  
        }  
    }  
}

than you can do like this

//Over controller  
[CustomExceptionFilter]  
public class HomeController:Controller 
{  
   //......  
}  


//Over the Action  
[CustomExceptionFilter]  
public ActionResult Index() 
{  
   //.......  
}
