Hi, Try this way try { // invoke code above } catch ( Exception ex ) { Error.PrintError(FlattenException(ex)); } Get Exception Details public static string FlattenException(Exception exception) { var stringBuilder = new StringBuilder(); while (exception != null ) { stringBuilder.AppendLine(exception.Message); stringBuilder.AppendLine(exception.StackTrace); exception = exception.InnerException; } return stringBuilder.ToString(); } Log Error to Log File public static bool PrintError(string msg) { try { string fullPath = System.AppDomain.CurrentDomain.BaseDirectory.ToString(); string date = DateTime.Now.Year + "-" + DateTime.Now.Month + "-" + DateTime.Now.Day; fullPath = fullPath + "Logs" ; if (!Directory.Exists(fullPath)) { Directory.CreateDirectory(fullPath); } string filePath = fullPath + "\" + date + " _ErrorLog.txt"; if (!File.Exists(filePath)) { TextWriter sw = new StreamWriter(filePath); sw.WriteLine( "Error Message :-" + msg); sw.Close(); } else { string oldLine = File.ReadAllText(filePath); TextWriter tw = new StreamWriter(filePath); tw.WriteLine(oldLine); tw.WriteLine(tw.NewLine); tw.WriteLine( "Error Message :-" + msg); tw.Close(); } } catch (Exception) { return false ; } return true ; } This way, you can capture exception log in file based on date.

Hi, Please try below code. static void Main(string[] args) { try { //your logic } catch (Exception e) { //will fetch method name that caused exception GetCallForExceptionThisMethod(MethodBase.GetCurrentMethod(), e) ; } } private static string GetCallForExceptionThisMethod(MethodBase methodBase, Exception e) { StackTrace trace = new StackTrace(e); StackFrame previousFrame = null; foreach (StackFrame frame in trace.GetFrames()) { if (frame.GetMethod() == methodBase) { break ; } previousFrame = frame; } return previousFrame != null ? previousFrame.GetMethod().Name : null; }
