Extract Line Number from Exception

Get the line number from Exception Class. Following code will give you Line number where exception is raised.

         private static int GetLineNum(Exception mexcption)

        {

            // Get stack trace for the exception with source file information

            var trace = new StackTrace(mexcption, true);

            // Get the very first stack frame

            var frame = trace.GetFrame(0);

            // Extract the line no from frame

            var line = frame.GetFileLineNumber();

            return line;

        }

You need to put pdb file along with exe.

You can use it like that

 private void ProceeEachFile()

        {           

            try

            {

               /* Some Code */

                throw new Exception("Some Error");

              /*Some Code */

             

            }

            catch (Exception ex)

            {

                var LineNum = GetLineNum(ex)

                throw new Exception(ex.Message + " Line Num -" + LineNum +"-->");

            }

        }

           In final method 

private void ByWorksheet(object ob)

        {         

           

            try

            {

              ProceeEachFile();

            }

           

            catch (Exception ex)

            {

                var line = GetLineNum(ex);

                String sLogData += ex.Message + " Line Num "+ line +"\n";

                MessageBox.Show(sLogData);

            }

           

        }
