How do I get the line numbers in the stack trace when an exception is thrown?

WordsLikeJared

Currently when an exception is thrown from within my Unity script while using my HoloLens the Debug Output shows the stack trace without the line numbers. Changing the build from Release to Debug doesn't give the line numbers.

How do I get the line numbers along with the stack trace? I'd be fine with it being logged somewhere else other than the Debug Output.

I tried looking around, and it looks like it's not showing the line numbers for others, as well: http://answers.unity3d.com/questions/1315985/null-reference-in-line-0.html

Thanks!

I think part of it can be due to where the exception is coming from. What exception are you hitting?

Typically if it is in your code you can double click on the exception and it will open visual studio to the line in question.

Double-clicking on the message in the Debug Output didn't open it. Here was the exception text:

Exception thrown: 'System.NullReferenceException' in Assembly-CSharp.dll
NullReferenceException: Object reference not set to an instance of an object.
   at NewBehaviourScript.Update()
   at NewBehaviourScript.$Invoke6Update(Int64 instance, Int64* args)
   at UnityEngine.Internal.$MethodUtility.InvokeMethod(Int64 instance, Int64* args, IntPtr method) 
(Filename: <Unknown> Line: 0)

I made a Cube and attached a NewBehaviourScript component. Here is the code:

public class NewBehaviourScript : MonoBehaviour {           
    // Update is called once per frame
    void Update ()
    {
        object a = null;
        a.GetType();    
    }
}

Oh wait, are you running in visual studio or Unity? I was assuming unity.

I think this sounds helpful for visual studio:

Visual Studio is where I'm running. I export from Unity using Build Settings and open the generate sln in Visual Studio.

The question on that site sounds like "How do I get line numbers from a dll compiled by Visual Studio that I've imported into Unity when running in Unity?" The pdb2mdb.exe tool converts .pdb files to a format understood by Unity's scripting engine. I don't think that will help me running from Visual Studio.
