Do you catch and re-throw exceptions properly?
A good catch and re-throw will make life easier while debugging, a bad catch and re-throw will ruin the exception's stack trace and make debugging difficult.
catch {}
catch (SomeException) {}
catch { throw; }
catch (SomeException) { throw; } Bad Example - Never use an empty catch block. Do something in the block or remove it.
catch (SomeException ex) { throw ex; }
catch (SomeException ex) { someMethod(); throw ex; } Bad Example - Never re-throw exceptions by passing the original exception object. Wrap the exception or use throw; instead.
catch (SomeException ex)
{
someMethod();
throw;
}
catch (SomeException ex)
{
someMethod();
SomeOtherException wrapperEx = new SomeOtherException("This is a wrapper exception", ex);
throw wrapperEx;
}Good Example - Good code
