Count Number of Lines in TextArea (Textbox) With Word Wrap [^] should help you out.

这也可以帮助您阅读所有内容文本文件中的行

this might also help you to read all the lines in a textfile

Dim oRead As System.IO.StreamReader
Dim FirstLine(1499) As String
oRead = IO.File.OpenText(Application.StartupPath & "\test.txt")
        Dim lineNo As Integer = 0
        While Not oRead.EndOfStream
            FirstLine(lineNo) = oRead.ReadLine
            lineNo += 1
        End While
