Getting the Exception object in a try..catch to include FULL stacktrace, currently its truncated

Question

can anyone help?

I am trying to get the full stacktrace when within a catch of try..catch. Currently its truncated to include only the current method where the error is....

Let me explain.. Currently i my stacktrace includes the method "Third" where the error happens but First and Second isn't included, i believe this is by design.

private void First()
{
    this.Second();
}

private void Second()
{
    this.Third();
}

private void Third()
{
    try
    {
        throw new SystemException("ERROR HERE!");
    }
    catch (Exception ex)
    {
        // I WILL LOG THE EXCEPTION object "EX" here ! but ex.StackTrace is truncated!
    }
}

I have seen a number of tricks to get the full stacktrace in a STRING but problem is my logging framework expects a object of type "Exception", but my variable (ex) which has my exception is valid but the property StackTrace is truncated.

Is there anyway i can receive a FULL exception with a FULL stacktrace so i am able to still send along my "EX" but this time it will have an UNtruncated stacktrace.

UnhandledErrror event seems to work as if i arrive here the Exception has a stack trace and is fully populated ...

I would really appreciated any feedback..

class Program
    {
        static void Main(string[] args)
        {
            try
            {
                First();
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.StackTrace);
            }
            Console.ReadLine();
        }

        private static void First()
        {
            Second();

        }

        private static void Second()
        {
            Third();

        }

        private static void Third()
        {
            throw new SystemException("ERROR HERE!");
        }
    }

The output in this case is:

   at stack.Program.Third() in C:\Temp\customers\stack\Program.cs:line 37
   at stack.Program.Second() in C:\Temp\customers\stack\Program.cs:line 31
   at stack.Program.First() in C:\Temp\customers\stack\Program.cs:line 25
   at stack.Program.Main(String[] args) in C:\Temp\customers\stack\Program.cs:li
ne 14

Update: I suddenly had doubts, and ran through all the solutions presented thus far. They all work, though Environment.StackTrace is the easiest. Here's what the output looks like:

==ex.StackTrace==
   at stack.Program.Third() in C:\Temp\customers\stack\Program.cs:line 35

==Environment.StackTrace per Guillaume/Jorge Córdoba==
   at stack.Program.Third() in C:\Temp\customers\stack\Program.cs:line 35   at S

Answer 2

string fullStackTrace = exception.StackTrace + Environment.StackTrace;

The current method may be added two times, if so, remove one line from one of the properties.

You need something like this :

        private static void Third()
        {
        try
        {
            throw new SystemException("ERROR HERE!");
        }
        catch (Exception ex)
        {
            // I WILL LOG THE EXCEPTION object "EX" here ! but ex.StackTrace is truncated!
            StackTrace st = new StackTrace(true);
            for (int i = 0; i < st.FrameCount; i++)
            {
                // Note that high up the call stack, there is only
                // one stack frame.
                StackFrame sf = st.GetFrame(i);
                Console.WriteLine();
                Console.WriteLine("High up the call stack, Method: {0}",
                                  sf.GetMethod());

                Console.WriteLine("High up the call stack, Line Number: {0}",
                                  sf.GetFileLineNumber());
            }
        }
    }

Hope this helps.

You don't understand how stack trace work. What is included in an exception trace is the "route" short to speak that the exception has traveled to reach the point where you're handling it.

Thus, on your example, it hasn't traveled at all yet, it's still in the "Third" method. If it would bubble up to "Second", then it would have gone across Third, to Second, and you'll be getting that on the stack trace.

I think what you actually want is the CallStack. Is the same concept, but the trace that's included in the exception is actually included "backwards" sort to speak, as the exception travels "up" to the place where it is handled.

Try logging the CallStack where you handle the exception.
