예외 스택 트레이스에서 '중복'메소드 이름을 제거하려면 어떻게해야합니까?

Question

전체 예외 및 스택 추적 부분 만 표시하고 싶습니다. 현재 예외에 대한 ex.ToString()을 호출하고 있지만 stacktrace 항목이 "중복"되었음을 확인했습니다.

내가 생각할 수있는 유일한 점은 라인 #을 무시하고 중복 문자열에 대한 문자열을 구문 분석하는 것입니다. 나는 정규식 패턴을 알아 내야 할 것 같다.

예는 : 스택 트레이스에 "ProcessTeleformFiles.ProcessExpTableRecord이 (..."두 번하지만 서로 다른 라인 #의 's의 나열이

내가 쓰는 거의 모든 단일 C# 4.0의 방법으로 시도의 catch 블록을 사용합니다.. 나는 사용자 지정 오류를 제기하고자 할 때

try 
catch (Exception) 
{ 
    throw; 
} 

그리고는 나는 기본적으로 표시 및/또는과 같이 오류 로그 코드의 루트 레벨에서 다음이

try 
catch (Exception ex) 
{ 
    throw new Exception("my custom message", ex); 
} 

을 수행합니다

try 
catch (Exception ex) 
{ 
    MessageBox.Show("Exception found: " + ex.ToString(); 
} 

스택 트레이스는 다음과 같이 할 수 그러나 :

내가 중복 메시지가하지 않는 오류 메시지를 원하는 반면, 이 같은 더 많은 :

UPDATE : 그래서 돌아 오는 길에 , 내 코드에서 모든 시도 어획량을 제거했다. stacktrace를 수정하는 유일한 상황은 사용자에게 좀 더 사용자 친화적 인 단순화 된 출력을 제공하는 한 곳에서입니다. 내부적으로 항상 전체 스택을 기록합니다. 모두에게 감사드립니다!

Answer 1

스택 추적의 추가 행은 "중복"되지 않으며 실행 흐름을 나타냅니다.이 경우 예외가 발견되어 다시 처리됩니다. 당신이 그 (것)들을 제거하는 경우에 당신은 무슨 일이 일어 났느가에 관하여 귀중한 정보를 제거하고있다. 언젠가는 당신이 오류를 디버그하려고 할 때 자신이 상처를 입히고 일어난 일을 해결할 수 없다.

해결책은 간단합니다. 은 try-catch 블록에 각 방법을 래핑하지 않습니다. 스택 추적을 복잡하게하고, 예외가 발견되어 다시 throw 될 때마다 성능 저하를 초래하고 특정 예외 유형을 잡는 것을 매우 어렵게 만듭니다.

각 메소드에서 예외를 포착하고 재실행하는 데 전혀 이점이 없습니다. 오류 메시지를 표시하여 처리하는 "루트 레벨"에있는 유용한 정보를 얻을 수있을 때이를 catch하면됩니다.

Answer 2

스택 트레이스에서 항목을 제거하면 더 이상 스택 트레이스가 아닙니다! 정확히 어떤 함수가 호출되었는지를 보여 주며, 함수가 스스로를 호출하면 주목할만한 정보입니다!
