advice needed

I have a CSV file that gets sent to my application once a day and once a day it runs an import now each line will always have either 32 or 33 items of data to insert.

This is my CSV file:

1,"1","Sinatra","Frank","The Lodge","Manor Drive","Sandown","Isle of Wight","PO30 998","01983 822008","","","","","",0,0,0,0,"","",0,0,0,0,0,0,0,"","","",""
2,"2","JORDAN","ROSE","52, DODNOR LANE","DODNOR IND EST","NEWPORT","I.O.W.","PO30 5XD","01983 822008","","","","","",0,0,0,1,"","",0,0,0,0,0,0,0,"","","","", ""

Line 1 has 32 columns of data to insert.
Line 2 has 33 columns of data to insert.

Now all I want is the 32 bits of data forgetting anything extra on each line.

How can I achive that in

//This is my insert code
 Dim _strInput As String = GetValueToInsert(_impData)
                If String.IsNullOrEmpty(_strTableColumns) Then Continue For
                Dim _strInsertCmd As String = "INSERT INTO " & _tableName & " (" & _strTableColumns & ") VALUES(" & _strInput & ");"
                Dim _cmdInsert As New SqlCommand(_strInsertCmd, _conn)
//This is how I find out what columns I have
Private Shared Function GetTableColumns(ByVal Connection As SqlConnection) As String
                Dim _strColumns As String = "SELECT Column_Name FROM information_schema.COLUMNS WHERE TABLE_NAME = '" + _tableName + "';"
                Dim _cmdColumns As New SqlCommand(_strColumns, Connection)
                Dim _strColumnNames As String = String.Empty
                Using _reader As SqlDataReader = _cmdColumns.ExecuteReader()
                    If _reader IsNot Nothing AndAlso _reader.HasRows Then
                        While _reader.Read()
                            If _reader("Column_Name").ToString() = "ident" Then
                                Continue While
                            End If
                            _strColumnNames = _strColumnNames & _reader("Column_Name").ToString() & ", "
                        End While
                    End If
                End Using
                Return RemoveLastOccurance(_strColumnNames, ", ")
            Catch ex As Exception
                'log exception and set status flag to false
                Logger.LogImportError(_tableName, ex)
                Return String.Empty
            End Try
        End Function
'I wrap each item of data in ''
        Private Shared Function GetValueToInsert(ByVal input As String) As String
                Dim _arrInput() As String = input.Split(",")
                Dim _output As String = String.Empty
                For i As Integer = 0 To _arrInput.Length - 1
                    _output = _output & "'" & _arrInput(i).Replace("""", String.Empty) & "', "
                Return _output
            Catch ex As Exception
                'log exception and set status flag to false
                Logger.LogImportError(_tableName, ex)
                Return String.Empty
            End Try
        End Function

this code will parse a csv file and return the items in an array

what do you mean by 32 bits.Is it 32 items or what?

yeah 32 items
richard_garAuthor Commented:
I mean I have a table with 32 columns and a CSV file which can be either 32 or 33 items each row but I only want to insert 32 items. How can I tell it to ignore the 33 item.
Split all into an array as you already know.

Then make a for loop to have 32 iterations and add it to other array like this

arrOld is the Parsed CSV items
for i = 0 to 31

arrNew(i) = arrold(i)

How about the following--it will give you back an un-parsed line consisting of 32 elements.
Private Function Get32(ByVal dataLine As String) As String
    Dim splitData() As String = dataLine.Split(","c)
    ReDim Preserve splitData(32)
    Return String.Join(",", splitData)
End Function

Actually, the line should be
ReDim Preserve splitData(31)

found it to be a problem if I had some data like so 'testing, 123' the , within the data was think it was for a new column.
