Integer.

This is an advanced member; it does not show in IntelliSense unless you click the All tab.

Blank lines and comments are not ignored when determining the line number.

This example searches for the name "Jones" in the text file and reports what line(s) it occurs on.

Using FileReader As New Microsoft.VisualBasic.FileIO.TextFieldParser("C:\ParserText.txt")
    FileReader.TextFieldType = Microsoft.VisualBasic.FileIO.FieldType.Delimited
    FileReader.Delimiters = New String() {","}
    Dim currentRow As String()
    While Not FileReader.EndOfData
        Try
            currentRow = FileReader.ReadFields()
            Dim currentField As String
            For Each currentField In currentRow
                If currentField = "Jones" Then
                    MsgBox("The name Jones occurs on line " & _
                    FileReader.LineNumber)
                End If
            Next
        Catch ex As Microsoft.VisualBasic.FileIO.MalformedLineException
            MsgBox("Line " & ex.Message & _
           "is not valid and will be skipped.")
        End Try
    End While
End Using
