Hi,
I have this code to read a CVS file. It reads each line, devides each line by delimiter ',' and stored the field values in array 'strline()' .
How do I extract only required fields from the CSV file?
For example if I have a CSV File like
Type,Group,No,Sequence No,Row No,Date (newline) 0,Admin,3,345678,1,26052010 (newline) 1,Staff,5,78654,3,26052010
I Need only the value of columns Group,Sequence No and date.
Thanks in advance for any ideas.
Dim myStream As StreamReader = Nothing
' Hold the Parsed Data
Dim strlines() As String
Dim strline() As String
Try
myStream = File.OpenText(OpenFile.FileName)
If (myStream IsNot Nothing) Then
' Hold the amount of lines already read in a 'counter-variable'
Dim placeholder As Integer = 0
strlines = myStream.ReadToEnd().Split(Environment.NewLine)
Do While strlines.Length <> -1 ' Is -1 when no data exists on the next line of the CSV file
strline = strlines(placeholder).Split(",")
placeholder += 1
Loop
End If
Catch ex As Exception
LogErrorException(ex)
Finally
If (myStream IsNot Nothing) Then
myStream.Close()
End If
End Try
