How to continue insert if one row fails
Dim WrongValuedLinesList As New List(Of String)
Dim ConversionFailedList As New List(Of String)
Dim InsertionFailedList As New List(Of String)
Dim NumberOfInsertedLines As integer = 0

For Each  (CurrentLine in my csv)
  ' 1. line processing
  Try
    ' (process my line : split, convert, check range...)
    If (I know the insertion will fail) Then
      ' (Store information about that wrong line, in List, log, or do nothing)
        WrongValuedLinesList.Add(" This line : " & CurrentLine 
                                              & " has wrong values because... 
        Continue For
    End If
  Catch ex as exception
    ' (here handle the line conversion failed : store in list, or log, or do nothing ...)
    ' for expl :   
       ConversionFailedList.Add(" Conversion failed for line " & CurrentLine 
                                      & " exception details : " & ex.message " )
  End Try
  ' 2. Line insertion
  Try
    '(insert my processed data into database)
     NumberOfInsertedLines +=1
  Catch ex as exception
    ' (here handle the insertion failed exception (expl : primary key might not be unique)
    '                      : store in list, log, do nothing...)
    ' for example :
    InsertionFailedList.Add(" Insertion failed for line " & CurrentLine 
                                      & " exception details : " & ex.message " )
  End Try
 Next
