how to read a specific csv line vb.net - vb.net

Question

ask permission,
I created a bot to input data to the web using vb.net and selenium.
Retrieve data from csv .
How to retrieve data from csv as needed, for example, there are 100 rows, only 30-50 rows are taken, for example. The loop code should not be looped at all.
Dim textFieldParser As TextFieldParser = New TextFieldParser(TextBox1.Text) With
{
.TextFieldType = FieldType.Delimited,
.Delimiters = New String() {","}
}
drv = New ChromeDriver(options)
While Not textFieldParser.EndOfData
Try
Dim strArrays As String() = textFieldParser.ReadFields()
Dim name As String = strArrays(0)
Dim alamat As String = strArrays(1)
Dim notlp As String = strArrays(2)
drv.Navigate().GoToUrl("URL")
Dim Nm = drv.FindElement(By.XPath("/html/body/div[1]/div[3]/form/div[1]/div[1]/div[1]/div/div[2]/input"))
Nm.SendKeys(name)
Threading.Thread.Sleep(3000)
Catch ex As Exception
MsgBox("Line " & ex.Message & "is not valid and will be skipped.")
End Try
End While
Thank you

Here's an example of using TextFieldParser to read one specific line and a specific range of lines. Note that I am using zero-based indexes for the lines. You can adjust as required if you want to use 1-based line numbers.
Public Function GetLine(filePath As String, index As Integer) As String()
Using parser As New TextFieldParser(filePath) With {.Delimiters = {","}}
Dim linesDiscarded = 0
Do Until linesDiscarded = index
parser.ReadLine()
linesDiscarded += 1
Loop
Return parser.ReadFields()
End Using
End Function
Public Function GetLines(filePath As String, startIndex As Integer, count As Integer) As List(Of String())
Using parser As New TextFieldParser(filePath) With {.Delimiters = {","}}
Dim linesDiscarded = 0
Do Until linesDiscarded = startIndex
parser.ReadLine()
linesDiscarded += 1
Loop
Dim lines As New List(Of String())
Do Until lines.Count = count
lines.Add(parser.ReadFields())
Loop
Return lines
End Using
End Function
Simple loops to skip and to take lines.
