Question : paths in vb.net

Sub setstarttimetonow()
        Dim writer As New StreamWriter("c:\\ians\\datafile.txt", True)
        writer.Write(Str(Now.Ticks))
        writer.Flush()
        writer.Close()
        starttime = Now

    End Sub
    Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If File.Exists("C:\\ians\\dataFile.txt") Then
            Dim reader As New StreamReader("C:\\ians\\dataFile.txt")
            starttime = New Date(Long.Parse(reader.ReadLine()))
            reader.Close()
        Else
            File.Create("C:\\ians\\dataFile.txt")
            setstarttimetonow()


paths aren't working in vb.net 2008 express tried c:\ians\datafile.txt and c:\\ians\datafile.txt

whats the correct way
