LINQ to SQL에서 SqlException을 catch하는 방법

내 WPF 응용 프로그램에서 LINQ to SQL을 사용하고 있으므로 SubmitChanges()을 호출하면 예외가 발생하지만 catch 할 수 없습니다. 여기 LINQ to SQL에서 SqlException을 catch하는 방법

는 관련 코드 :

try 
{ 
    FeatureDataContext.Features.InsertOnSubmit(newFeature); 
    FeatureDataContext.SubmitChanges(); 
} 
catch (SqlException sqlEx) 
{ 
    System.Windows.MessageBox.Show("CreateNewFeature : " + sqlEx.Message); 
}

그리고 이것은 위가 던지는 예외 :

Exception Info: System.Data.SqlClient.SqlException 
Stack: 
    at System.Data.Linq.DataContext.SubmitChanges(System.Data.Linq.ConflictMode) 
    at System.Data.Linq.DataContext.SubmitChanges() 
    at [....]

어떻게 WPF 응용 프로그램에서 SqlException을 잡으려고?

나는 SubmitChanges()이 예외를 발생시키지 않는 것을 보았습니다. 그러나 예외 지점을 발생시킨 코드는 SubmitChanges()을 호출하는 코드입니다.

예외의 전체 스택 추적을 포함 할 수 있습니까? –

@Pavlo : 완료 ... – Nawaz

당신이 제공하는 시도-catch 블록이 (스택 트레이스보고)를 CreateNewCategory 내부에있는 경우, 방법 및 유형 :

전체 예외가 이것이다 실제로 던져 질 예외의 SqlException, 그때 잡아야한다.

또는 응용 프로그램에서 모든 예외를 catch하려면 UI 스레드에서 예외의 경우 Application.DispatcherUnhandledException 이벤트를 구독하고 다른 스레드에서는 예외의 경우 AppDomain.CurrentDomain.UnhandledException을 구독해야합니다.

Application.DispatcherUnhandledException 및 AppDomain.CurrentDomain.UnhandledException은 오류를 기록하고 정상적으로 응용 프로그램을 충돌 시키도록 사용해야합니다. 이러한 이벤트를 사용하여 예외를 복구하려고 시도하지 마십시오. – Phil
