vb.net中的SQLexception

Answer 2

Try 
     'Do your stuff 
Catch ex as SqlException 
     Dim errors = ex.Errors 
     ' inspect errors to decide if this is the condition you want to catch 
     Dim shouldCatch As Boolean = ... 
     ' Code that acts on the specific error condition 
     If shouldCatch Then 
     Else 
     Throw ' rethrow everything we're not interested in 
     End If 
End Try
