You need to split the text box text into an array of strings based on the line separator and then, if you have enough lines, get the line from the array:

    Dim asLines As String()
    Dim wLineToGet As Integer = 2
    asLines = TextBox1.Text.Split(New String() {Environment.NewLine}, StringSplitOptions.None)
    If asLines IsNot Nothing AndAlso asLines.Length >= wLineToGet Then
        MessageBox.Show("Line " & wLineToGet & " = " & asLines(wLineToGet - 1))
    Else
        MessageBox.Show("There are not enough lines in the textbox to retrieve line " & wLineToGet)
    End If
