Is this caused by not having a pdb file? What is it and how to get it? (I am using ASP.net) –Brabbeldas Sep 27 '13 at 9:58 6 Why are you using GetFrame(0)? I would think that you should be using GetFrame(FrameCount-1). &ndash

UPDATE: My application is divided into three class library projects and one ASP.NET "website" project. The error I am trying to track down is in one of the three class library projects. I only deployed the pdb file for the class library project that is generating the "Object reference not set to an instance of an object" error.

Click on the Build "vertical tab". Select "Release" configuration. Check the DEBUG constant parameter. Uncheck the "Optimize code" parameter to avoid the occasional trace issue with inlined code (this step is not essential). Press the Advanced... button and choose Output -> Debug Info -> pdb-only. Deploy the generated .pdb file with the assembly. share|improve this answer edited Mar 10 '09 at 2:15 RoadWarrior 13.6k1064114 answered Mar 10 '09 at 1:01 Coxy 6,33832153 2 Do I have to deploy the pdb file along with the assembly? –Michael Kniskern Mar 10 '09 at 1:10 7 Yes. That's where the debug symbols and line numbers are at. –John Saunders Mar 10 '09 at 1:21 4 You probably don't want to expose this information if you don't have to. Use it to debug a clients problem, yes. But you don't always want to do it because debugging information can give away sensitive data and be an attack

To get the error details I do something like this: Dim ex As Exception = HttpContext.Current.Server.GetLastError() If TypeOf ex Is HttpUnhandledException AndAlso ex.InnerException IsNot Nothing Then ex = ex.InnerException End If If ex IsNot Nothing Then Dim s As New StringBuilder s.AppendLine("Message:" & get line number Environment.NewLine & ex.Message & Environment.NewLine) s.AppendLine("Source:" & Environment.NewLine & ex.Source & Environment.NewLine) s.AppendLine("Stack Trace:" & Environment.NewLine & ex.StackTrace) ' ... email code here ... End If I realised today however that it would be much more useful to also have the filename of the misbehaving page, plus the line number. Currently this is not within the stack trace where I thought it would be. Can anyone advise how I can include this information? Thanks. Reply santa_1975 Contributor 5601 Points 1490 Posts Re: Obtaining exception line number using Server.GetLastError Aug 07, 2008 04:59 AM|santa_1975|LINK You can use the StackTrace and StackFrame from the System.Diagnostics as below. StackTrace st = new StackTrace(new StackFrame(true)); StackFrame sf = st.GetFrame(0); Console.WriteLine("File Name: {0}", sf.GetFileName()); Console.WriteLine("Method Name: {0}", sf.GetMethod().Name); Console.WriteLine("Error Line Number: {0}", sf.GetFileLineNumber()); Console.WriteLine("Error Column Number: {0}", sf.GetFileColumnNumber());Hope this helps.

RSS reddit Tweet JParrish Aug 24, 2007 at9:04AM Hoping someone may have overcome this before.I use the enterprise library exception handling block to email myself any errors that occur within my ASP.NET application. At one time, I was getting the line numbers of the exceptions. I realize the performance hit but it is ok while I am testing deployment in new environments. Lately I have not been able to get the line numbers any more which makes the error too ambiguous. I have my build configurations to active debug, and in the web.config compilation debug is true.For libraries I call from the web app, I have the pdb files deployed into the bin folder. Does anyone know anything more I can check/do to try and get the exception to include the line number? I am using fixed name single page assemblies if that matters. ScanIAm This isan...
