How to Parse a comma delimited txt file?

I'm a noob so I'm not sure how to put this exactly.
I'd like to parse a comma delimited text file into an (array?) and use the contents of the array to fill in a webform.

FIRSTNAME,LASTNAME,ADDRESS,ETC....
Ralph,Malph,123 st, etc....

I've already got the webform portion handled but I've been getting my data from labels I have on my form ie:

Dim FirstName As String
FirstName = lblFirstName.Text
.Document.Frames("Main").document.Forms(0)("app_first_name").Value = FirstName
ETC.

But thats kinda cheating, I'd like to do it without using labels, just pull the data from memory.

How would I go about doing that?

Something like this?...

        Dim fileName As String = "C:\someFile.txt"
        If Not File.Exists(fileName) Then
            MsgBox(fileName, MsgBoxStyle.Critical, "File Not Found")
            Exit Sub
        End If

        Dim sr As StreamReader = New StreamReader(fileName)
        Dim inputLine As String = sr.ReadLine
        sr.Close()
        If Not (inputLine Is Nothing) Then
            Dim values() As String = Split(inputLine, ",")
            .Document.Frames("Main").document.Forms(0)("app_first_name").Value = values(0)
            .Document.Frames("Main").document.Forms(0)("app_last_name").Value = values(1)
            ' etc...
        End If
