Update to the answer
// Get stack trace for the exception with source file information
var st = new StackTrace(ex, true);
// Get the top stack frame
var frame = st.GetFrame(st.FrameCount-1);
// Get the line number from the stack frame
var line = frame.GetFileLineNumber();
I added an extension to Exception which returns the line, column, method, filename and message:
public static class Extensions
{
public static string ExceptionInfo(this Exception exception)
{
StackFrame stackFrame = (new StackTrace(exception, true)).GetFrame(0);
return string.Format("At line {0} column {1} in {2}: {3} {4}{3}{5} ",
stackFrame.GetFileLineNumber(), stackFrame.GetFileColumnNumber(),
stackFrame.GetMethod(), Environment.NewLine, stackFrame.GetFileName(),
exception.Message);
}
}
Check this one
StackTrace st = new StackTrace(ex, true);
//Get the first stack frame
StackFrame frame = st.GetFrame(0);
//Get the file name
string fileName = frame.GetFileName();
//Get the method name
string methodName = frame.GetMethod().Name;
//Get the line number from the stack frame
int line = frame.GetFileLineNumber();
//Get the column number
int col = frame.GetFileColumnNumber();
Working for me:
var st = new StackTrace(e, true);
// Get the bottom stack frame
var frame = st.GetFrame(st.FrameCount - 1);
// Get the line number from the stack frame
var line = frame.GetFileLineNumber();
var method = frame.GetMethod().ReflectedType.FullName;
var path = frame.GetFileName();
In Global.resx file there is an event called Application_Error
it fires whenever an error occurs,,you can easily get any information about the error,and send it to a bug tracking e-mail.
Also i think all u need to do is to compile the global.resx and add its dll's (2 dlls) to your bin folder and it will work!
I tried using the solution By @davy-c but had an Exception "System.FormatException: 'Input string was not in a correct format.'", this was due to there still being text past the line number, I modified the code he posted and came up with:
int line = Convert.ToInt32(objErr.ToString().Substring(objErr.ToString().IndexOf("line")).Substring(0, objErr.ToString().Substring(objErr.ToString().IndexOf("line")).ToString().IndexOf("\r\n")).Replace("line ", ""));
This works for me in VS2017 C#.
If you don't have the .PBO
file:
C#
public int GetLineNumber(Exception ex)
{
var lineNumber = 0;
const string lineSearch = ":line ";
var index = ex.StackTrace.LastIndexOf(lineSearch);
if (index != -1)
{
var lineNumberText = ex.StackTrace.Substring(index + lineSearch.Length);
if (int.TryParse(lineNumberText, out lineNumber))
{
}
}
return lineNumber;
}
Vb.net
Public Function GetLineNumber(ByVal ex As Exception)
Dim lineNumber As Int32 = 0
Const lineSearch As String = ":line "
Dim index = ex.StackTrace.LastIndexOf(lineSearch)
If index <> -1 Then
Dim lineNumberText = ex.StackTrace.Substring(index + lineSearch.Length)
If Int32.TryParse(lineNumberText, lineNumber) Then
End If
End If
Return lineNumber
End Function
Or as an extentions on the Exception class
public static class MyExtensions
{
public static int LineNumber(this Exception ex)
{
var lineNumber = 0;
const string lineSearch = ":line ";
var index = ex.StackTrace.LastIndexOf(lineSearch);
if (index != -1)
{
var lineNumberText = ex.StackTrace.Substring(index + lineSearch.Length);
if (int.TryParse(lineNumberText, out lineNumber))
{
}
}
return lineNumber;
}
}
You could include .PDB
symbol files associated to the assembly which contain metadata information and when an exception is thrown it will contain full information in the stacktrace of where this exception originated. It will contain line numbers of each method in the stack.
Simple way, use the Exception.ToString()
function, it will return the line after the exception description.
You can also check the program debug database as it contains debug info/logs about the whole application.
static class ExceptionHelpers
{
public static int LineNumber(this Exception ex)
{
int n;
int i = ex.StackTrace.LastIndexOf(" ");
if (i > -1)
{
string s = ex.StackTrace.Substring(i + 1);
if (int.TryParse(s, out n))
return n;
}
return -1;
}
}
try
{
throw new Exception("A new error happened");
}
catch (Exception ex)
{
//If error in exception LineNumber() will be -1
System.Diagnostics.Debug.WriteLine("[" + ex.LineNumber() + "] " + ex.Message);
}
