How to create error log in MVC 5

Question

I have created a project in MVC5, I want to create an error log for same.

 

is there any way that we can get detailed information about the error. 

 

as of now, i am catching exception like below. 

 

catch (Exception Ex)

{

mailobj.SendMail(

this.ControllerContext.RouteData.Values["controller"].ToString(),

this.ControllerContext.RouteData.Values["action"].ToString(),

Convert.ToString(Ex.Message.Replace("<", "").Replace(">", "").ToString()),

Convert.ToString(Ex.HelpLink),

Convert.ToString(Ex.Source),

Convert.ToString(Ex.StackTrace),

Convert.ToString(Ex.TargetSite));

return Json("error in the system.!", JsonRequestBehavior.AllowGet);

}

 

hear send mail will send mail to admin about error.

 

but the problem is, I could not able to get complete details about the error for example, if you get error message like "Object reference not set to an instance of an object." I want to to what is the parameter value to get this data.

 

Is there any easy way that we can track the errors in the system.
